Stage 3 Research on Cyclone, Drought or Floods by Mrs Sim

Thomas 6N

2021-08-24 22:34:39 UTC

Floods happen when the capacity of the rivers is not enough to carry the water that has entered the river network, and the banks overflow. Floods are caused by prolonged or heavy rainfall. Cyclones bring huge amounts of moisture inland from the ocean and are a major cause of floods, particularly in coastal areas.

The magnitude (or size) of a flood event can be expressed in many ways, but the peak level of the water at a particular location in a waterway is the most unambiguous and easy to measure. This is measured by a river gauging station.

Floods impact on both individuals and communities, and have social, economic, and environmental consequences. The consequences of floods, both negative and positive, vary greatly depending on the location and extent of flooding, and the vulnerability and value of the natural and constructed environments they affect.

Great info on floods. Good research on causes and effects!

When rainfall is less than normal for a period of weeks to years, streamflows decline, water levels in lakes and reservoirs fall, and the depth to water in wells increases. If dry weather persists and water-supply problems develop, the dry period can become a drought.
A perfect definition of the causes of drought, Oscar!

Floods are a natural process that can be caused by a number of factors and affected by human causes floods can occur at irregular times. Any flood the happens will never be the same as the one happens before or after.
Great information Jess. Good job!

Cyclones are large revolving tropical storms caused by winds blowing around a central area of low atmospheric pressure. The energy created from the thunderstorms can then add to the whole system and a tropical cyclone will form. Cyclones rely on the circulation of Earth, so they form away from the equator. Cyclones form with a combination of very warm sea surface temperatures and the right type of outflow. A tropical cyclone needs two main ingredients: a cluster of thunderstorms and a warm body of water – at least 27ºC – from which the storm gathers its energy. The warm, tropical ocean under a developing storm evaporates then condenses to form clouds, releasing heat throughout the process. The main parts of a tropical cyclone are the rainbands, the eye, and the eyewall. Air spirals in toward the center in a counter-clockwise pattern in the northern hemisphere (clockwise in the southern hemisphere), and out the top in the opposite direction.

Good info Keira! Poor man in the picture. I think he is having a bad day!

Tropical Cyclones start as a tropical low a low pressure system forming off land. When the the winds around the center of the tropical low get to 63 km/h it is classified as a cyclone and named. The cyclone's fuel is mostly from warm water and evaporated water in the air so when cyclones go on land they won't go too far before becoming a normal storm again.
Great info and pic on tropical cyclones Levi!

When rainfall is less than normal for a period of weeks to years, streamflows decline, water levels in lakes and reservoirs fall, and the depth to water in wells increases. If dry weather persists and water-supply problems develop, the dry period can become a drought. Examples of drought impacts on society include anxiety or depression about economic losses, conflicts when there is not enough water, reduced incomes, fewer recreational activities, higher incidents of heat stroke, and even loss of human life. Drought conditions can also provide a substantial increase in wildfire risk. Usually the dirt and ground start cracking into different pieces.
Good info on the causes and effects of drought conditions Franklin!

Alex 5B

2021-08-24 23:45:50 UTC

Cyclones form when a cluster of thunderstorms start occurring on warm tropical oceans. If the cluster continues in low pressure, it starts rotating If that cluster persists in an area of low pressure, it will rotate. If the conditions are right, then the cluster will grow and develop into a tropical cyclone.

That you tube clip shows it perfectly! Well done Alex!

A flood is when land that is usually dry is submerged by an overflow of water.
There are five different types of flooding and they are aerial, catastrophic, coastal, riverine and urban flooding.
Aerial flooding is caused by heavy rainfall or snowmelt.
Catastrophic flooding is caused by infrastructure failure, like the failure of a levee or dam.

Excellent info Charlotte! Gee I miss you.Say hi to the family.

Alyssa & Ava 6G

2021-08-24 23:57:00 UTC

A flood is when there is an overflow of water which goes higher than its normal limits, especially over what is normally dry land. the flood almost or does fully submerge things within, it may be buildings, cars animals or even people. Floods can be caused by many things like a dam breaking or a lake overfilling, but when floods comes to our minds, usually rain comes to mind. floods can happen very easily especially when it is raining, this is why its dangerous to be in a flood zone during a storm. if you are in a dangerous area or a flood zone, it will be safer to evacuate the premises.
Well answered you too! The silly bloke in the rubber ducky must not know flood waters carry all sorts of diseases!

Cyclones are one of the most known natural disasters and are very dangerous due to its heavy winds. They can also drown swimmers. A cyclone can develop in water or land and can live in either. Cyclones are an atmospheric system characterised by rapidswirling air masses around a low-pressure core, which is typically accompanied by stormy and often destructive weather. Cyclones are storms that originate in the Southern Pacific.
I love your illustration to go with your good info, Archie!

Nicholas 6G

2021-08-25 00:05:06 UTC

Cyclones are caused when warm ocean air (26 Degrees Celsius or above) is mixed with strong winds which then might travel to land and cause destruction.

Cyclones are measured in wind speed. A category 1 cyclone can reach speeds of up to 125kmh, a category 2 cyclone can get as fast as 164kmh, a category 3 cyclone can hit top speeds of 224kmh, a category 4 cyclone can reach speeds of up to 279kmh and a category 4 cyclone reaches its top speed at 279 or more.

P.S A cyclone is also a sports team.
Great info, what do the Cyclones play? Soccer, NFL?

A tropical Cyclone is formed when a huge part of non-frontal creates pressure over a body of water. This force is very strong as the particles grabbed from the water bounce on top of themselves.

Droughts occur when there is a period of below-average rainfall in a particular area. This can cause top soil to dry out, groundwater to sink and streams and rivers to dry up. Living organisms need water to survive. Because of this, droughts are one of the worst natural disasters that can occur. Prolonged drought can cause plants and animals to die. This can lead to famine for the human population. If you want a more detailed explanation about droughts, floods and climate change, watch the documentary. It is very good.
Good on you Sean!

Drought is defined as a period in which a region has a deficit in its water supply. Drought is a normal feature of climate which happens in all climate zones from time to time.

Usually, drought is talked about in one of two perspectives- meteorological and hydrological.
You are the STUDENT of THE DAY, three great posts. Well done!

hayanaif1 — 2021-08-25 00:38:47 UTC

A cyclone is a system of winds rotating inward to an area of low barometric pressure ,with an anticlockwise or clockwise circulation. The destructive winds associated with cyclones can cause extensive property damage and turn flying debris into potentially lethal weapons. Trees can be flattened, buildings and roads destroyed and other infrastructure such as signs and powerlines can also be torn down by excessive wind .

it is definitely deadly and I'm sure all of us wouldn't like this roaring into your house on a normal day like so.
You are right Haya, my mum still remembers being in a cyclone in Townsville with me when I was a baby. Top picture too!

Ellie 6N

A cyclone is a violent tropical storm with very strong winds and heavy rain that can cause extensive property damage and injuries to people. The eye or center of the cyclone is an area made up of lights winds and often clear skies.
Good on you, Ellie. Love how the GIF shows the way cyclones move.

A cyclone is a powerful spinning storm that contains strong winds and rains. It can cause massive damage to property and can lead to loss of life. The 'eye' of a cyclone is the center and there are less powerful winds in there. A cyclone is constantly spinning anticlockwise in the northern hemisphere and clockwise is the southern hemisphere.

cyclones are wind storms over a certain body of water. Accompanied with heavy rainfall the winds of an cyclone is measured in a certain unit anemometers. their is also the Dvorak Technique it is used to measure a cyclones intensity based on infra-red visible cloud patterns. Powerful waves generated during cyclones can seriously damage habitats and landforms, particularly coral reefs and shorelines. Cyclonic winds can also cause substantial changes in the shape of islands and coastlines, affect ocean currents. Good info, Roshan. Not sure why it isn't showing properly but you can read it when you click on it!

Ellie 6N

2021-08-25 00:49:22 UTC

Flooding occurs most commonly from heavy rainfall when natural watercourses do not have the capacity to carry excess water. However, floods are not always caused by heavy rainfall. In coastal areas, water inundation can be caused by a storm surge as a result of a tropical cyclone, a tsunami or a high tide coinciding with higher than normal river levels. If a dam fails, triggered for example by an earthquake, the downstream area will flood, even in dry weather conditions.
Poor Pooh, his honey will wash away!

Mouksha 6N

2021-08-25 00:55:08 UTC

What causes a cyclone?
A cyclone is formed when warm, moist air over the ocean rises upward from the surface of the ocean. As this air moves up and away from the ocean's surface, it leaves less air near the surface. So as the warm air rises, it causes an area of lower air pressure below it and higher pressure air from above flows down into the eye.
Excellent post Mouksha. I miss you Miss M!

Maeve Fisher 6G - Floods

2021-08-25 01:07:44 UTC

A flood may be a extraordinary flowing or flooding of water onto land that's not usually covered by water. A flood happens when a lot of rain falls, brought by storms and strong winds.
Well done Maeve, great post! Both Kinder and Stage 1 are using your story next week. Thank you!

Riley 6N

2021-08-25 01:09:33 UTC

Floods are caused by prolonged and heavy rainfall or the melting of snow and ice. We will see that floods will become more common as rising temperatures melt icecaps and put more water in the oceans and eventually end up on land.

Great post, great pic, miss you!

Paige 6N

2021-08-25 01:12:18 UTC

A drought is when there is significantly less rain than there usually is over a long period of time (months to years). Stream flows decrease and water levels in lakes and rivers go down. If the dry weather continues and water-supply drops, the dry period can become a drought. The top 5 most drought prone countries in the world are Ethiopia, Sudan, Eritrea, Afghanistan and China.
Great post Paige! Have you thought about recording reading a story for Kinder. You would be SO good at it! Pop into the debating GC and have a look. Think it over, no pressure!

A flood is when there is heavy rainfall and then the water has no where to go. Floods come from all over the world and can reach depths of 9.144m! Floods are very dangerous and can force roads to close and people to evacuate there homes. Some floods are so dangerous they can even kill people. A flood is actually the most common natural disaster. The worst flood in history happened in 1931 in Yangzi river in China.

Droughts consists of dry land when rain is much less than its normal habitat. Usually, It is called a "drought" when it hasn't shown rain in months or even possibly years. Water levels decrease, which means some people start to follow simple saving water rules. Some causes of drought is unusual air circulations, heat ( heat is most common), and less soil moisture.
Great information Heliya and a great hunt!

Cyclones are a heavy rain fall and wind that can reach up to 150 kilometers per hour. It can cause heavy destruction to properties and lives. The formation of a cyclone is a process that is termed as tropical cyclone genesis. These cyclones are formed all over places in the oceans near the equator. They sometimes go on land as well. The biggest cyclone ever was in Cuba at 1924 and it reached up to 275 kilometers per hour!
I'm glad I wasn't in CUBA in 1924! Love your GIF!

Drought - Natalie 5B

2021-08-25 01:55:44 UTC

Droughts are a long period of time with low rainfall which leads to shortages of water. Droughts affect crops, animals and land. some farmers who are in drought, have to buy hay and hand feed their animals. Between 1979-11983, almost all eastern Australia was affected by a major drought. In 2011, Adelaide installed a stage 1 of the Desalination plant and in 2012 they completed stage 2. But in 2013 it was officially on the 26th of March.
Brilliant Aussie information about drought Natalie. That will help everyone with their projects in Week 8 and 9!

Chloe 6G

2021-08-25 02:09:01 UTC

Drought is a period of time when a particular area or region receives below normal precipitation. Because of this, it can cause reduced soil moisture or groundwater, diminished stream flow, crop damage and general water shortage. Droughts are the second-most costly weather crisis.
Unlike sudden weather events like thunderstorms, hurricanes and tornados, droughts are very difficult to pinpoint when it has started or when it has ended. The initial effects of a drought are difficult to identify right away, so it may take weeks, months or even years to determine if a drought has started. The end of a drought goes the same way. A drought can last for a long time. Sometimes droughts can last for a decade or more in a region. The longer a drought lasts, the more harmful it can be to people.
Droughts can affect people in several ways. Clean water may not be accessible when a drought happens in that area. Without the presence of water, people have to bring water from elsewhere to survive. Water is also essential for crops to grow. When not enough precipitation happens to naturally water them, the crops need to be watered by people. That can only happen when there is enough water from nearby streams and rivers. But during a drought this may not even happen as these water sources would be dried up, preventing crops to be watered and causing them to die off.
Sorry Chloe, I missed reading yours earlier! It as great post! Well done!

Cohen Winley 6n. Floods

2021-08-25 02:13:59 UTC

In terms of lives lost and property damaged, floods are just behind tornadoes as the top natural disaster. In the United States, flood damages totaled $8.41 billion in 2011. There were 113 flood-related deaths. Floods can affect any area to some degree; wherever rain falls, flooding can occur.

As water falls to the Earth in the form of rain or snow, it seeps into the ground. But if the ground is frozen or the surface impervious (asphalt or concrete are two contenders) or the soil is already saturated and cannot absorb the water faster than it falls from the sky, problems arise.
Hey Cohen, l really like the picture with your post. Wouldn't it be horrible to have that happen to your home!

Matilda 5B-Drought

matildagrant5 — 2021-08-25 02:17:18 UTC

Droughts are long periods of time with little or no rain.
I chose drought, because my Aunty Joanne lives in Tamworth, and for a while, she was in drought and she had to buy lots of hay for her horses, instead of them also eating grass, which costs a lot of money for the 3 of them. Also, all her paddocks, front and back yard and gardens were tan-colored, and completely dry.
When we visited, we could only have minute long showers, with on and off hot and cold water. For the dishwasher, the tap and the shower, and other water-using items in the house had rain water coming out, because we couldn't waste fresh drinking water.
All water to be drank was from bottled water, and it also costs money.
This absolutely fascinated me Matilda! You have shown the personal side of drought. And drought in sign language. You never cease to amaze me superkid!

What causes floods?

The main causes for the occurrence of floods include: Rainwater that is essential to sustain life, is often the very cause of mass destruction. Incessant heavy rains cause water-logging in the streets and also contribute to an increase in the water level in the water bodies.
Well done Hayley! I love the word incessant, didn't we have some incessant rain yesterday!

Droughts by Hayley 6G

2021-08-25 02:26:54 UTC

What causes droughts?

Droughts can be caused by a number of things. The most important drought cause is related to how much water vapor is in the atmosphere because water vapor in the atmosphere is what causes precipitation. When there are moist, low pressure systems, precipitation, such as rain, hail, sleet, and snow can occur.
This post is great too! Well done Hayley! You always go above and beyond!

Floods can be very catastrophic like in this picture.
They can be caused by large rainfall in mountains and such flooding into the lower area. They can also be caused by lots of rainfall for weeks like the floods this year.
Flash floods are extremely dangerous as they come without warning.

Cyclones are caused when moist air over the ocean rises upward from near the surface. Cyclones are measured between 1 - 5 meaning 1 is not so dangerous and 5 is extremely dangerous. Cyclone Mahina was the deadliest cyclone Australia has ever experienced. This cyclone was recorded category 5 meaning that it spread a lot of destruction. The effect of a cyclone is destructed habitats and landforms, coral reefs and shortlines and ca change the shape of islands.

Youssef 56A Flood

2021-08-25 02:33:15 UTC

Flood water is an enormous amount of overflow of water that submerges on land. Floods are caused by atmospheric conditions that cause heavy rain.

River Flood

River floods usually occur when there is a tropical storm, continuing thunderstorm and excessive amount of rainfall.

Costal Floods

Coastal flooding is usually caused by Storms and Tropical Cyclones. This usually results in high tide levels, high winds and Tsunami.

Flooding Damages

Flooding can cause loss of human life and wild life. It also causes major damages to buildings, environmental damages such as tress and crops.
This information is really good and it will be helpful for the science Project in weeks 8 and 9.

Cyclones by Campbell

Cyclones are large revolving tropical storms caused by winds blowing around a central area of low atmospheric pressure Cyclones develop over warm waters in the tropical regions of the oceans where areas of very low pressure are created by air being heated by the sun.

The "Dvorak Technique" has been used to measure cyclone intensity, based on infra-red and visible cloud patterns, which are then matched to wind speed

The effects of tropical cyclones include heavy rain, strong wind, large storm surges near landfall.
Very interesting info on the "DVORAK technique" You taught me something today!

A Cyclone is a huge storm that usually forms near ocean. The center of a cyclone is called the eye which is the calmest part, the eye wall surrounds the eye where the most damaging winds are found. It can range anywhere from 5 to 30 miles!
then comes the rain bands which surround the eye wall. These bands are a series of dense clouds that give a pin wheel appearance to the cyclone, which range from 50 to 300 miles!
Cyclones are divided into 5 categories depending on the speed of their wind. Categories 3, 4 and 5 are the most dangerous part of the Cyclone.
A huge cyclone can release energy equivalent to 10 atomic bombs per second. did you know that any cyclones in the pacific ocean is called typhoons?

Surviving Cyclones ~ Ruby Cuelho 6G

2021-08-25 03:02:53 UTC

Cyclones can be one of the most dangerous natural disasters out there. They are catastrophic, and merciless, so first lets get some facts.
Cyclones are created when some tropical storms form over oceans. If that storm has an area of low pressure, it will start spinning. And worse, if the temperature and pressure is correct, then it can sustain itself for long enough to travel. It will also grow in size.
But how can we survive them?
Well, this would be no easy thing. First, you need to keep track and listen to people and websites, like this:
http://www.bom.gov.au/cyclone/
If this website tells you that a cyclone may be coming, you need to prepare.
But how?
First of all, you need to turn off all electricity, gas, and water, and unplug all appliances.
Then, clear your property of loose small items, and tie down or secure large items, otherwise they could go flying in the pressure and wind of the tropical cyclone.
Close blinds, shutters and curtains, and use strong tape so that any broken glass doesn't come off and injure someone.
Also, wear strong shoes, and tough clothing for protection. Definitely don't wear thongs, shorts and a t-shirt. lock doors and windows.
It also helps to have an evacuation emergency kit, so that is you have to leave your home, you have what you need. This could include a first aid kit, a water bottle, warm clothing, and maybe something small important to you that you would not want to loose.
Now you no how to stay safe in a tropical cyclone... hopefully you will not have to need to use this information though.
Now that's a post Ruby! Well done! That was very interesting to investigate how to survive a cyclone. Great info.

Drought is a dry period in the natural climate cycle that can occur anywhere in the world. It is a slow disaster that is caused by the lack of precipitation, resulting in a water. shortage. They are caused by drier than normal conditions that can eventually lead to really hot temperatures and can make a drought worse by evaporating moisture from the soil. Droughts don't just happen in hot and dry places.
Great info, Zarah. That picture says it all...so dry!

floods by hamilton

2021-08-25 03:16:33 UTC

Floods can have both positive and negative impacts. They can bring welcome relief for people and ecosystems suffering from prolonged drought, but also are estimated to be the costliest natural disaster in Australia.

Standing flood waters can also spread infectious diseases, contain chemical hazards, and cause injuries. Each year, flooding causes more deaths than any other hazard related to thunderstorms. The most common flood deaths occur when a vehicle is driven into hazardous flood waters.

Flooding occurs most commonly from heavy rainfall when natural waterways cannot cope with the excess water. They can also be a result of a tropical cyclone, a tsunami, or a high tide coinciding with higher-than-normal river levels. Another way could be if a dam failed for example by an earthquake, the downstream area would flood, even if the weather condition is dry.

Dam failures are potentially the worst flood events. A dam failure is usually the result of neglect, poor design, or structural damage caused by a major event such as an earthquake. When a dam fails, a gigantic quantity of water is suddenly let loose downstream, destroying anything in its path.

This information is so accurate Hamilton. In Australia we can go from drought to flood in the blink of an eye!

Yes HAMILTON this is great work!!!!!!Mrs Sim

Floods are created by different things such as a broken dam and too much rainfall. They impact the society by forcing families out of their houses and maybe sometimes on their roof!

cyclones by Patrick 5B

2021-08-25 03:31:48 UTC

Cyclones can be most intense storms on earth. A cyclone is a system of winds rotating counterclockwise in the northern hemisphere around a low presser center. The swirling air rises and cools, creating clouds and precipitation.

their are two types of cyclones : middle latitude (mid-latitude) cyclones and tropical cyclones.

mid-latitude

mid-latitude cyclones sometimes called extratropical cyclones, form at the polar front when the temperature difference is between two air masses.

tropical cyclones

tropical cyclones are low presser systems that form over warm tropical waters. they typically form when the sea surface temperature is above 26.5 degrees.
Good research, Patrick. That picture really shows the eye of the storm.

Cyclones - Elyane 5/6A

2021-08-25 03:38:26 UTC

Cyclone's are caused when warm moist air that is covering the ocean rise's up from the nearest surface causing it to create a deadly cyclone. An anemometer is usually used to measure wind speed or wind stream speed, though people used a technique called the Dvorak technique to measure a Cyclone's intensity using the anemometer.

Cyclone's can do great damage to various things, such as buildings, animal habitat's, landform's and usually even precious coral reef's underwater. Cyclone's can also last around 3-7 days but the really large Cyclone's can last weeks! The longest Cyclone ever recording was back in 1994 and lasted 4 weeks and 2 days! (30 days)

A cyclone's speed is is around 90km, but the most severe cyclone's speed is usually 280km.Cyclone's also usually form in the south pacific and Indian ocean.

Floods

What Causes Them?
Floods are caused by overflowing lakes, rivers, by heavy rainfall or when snow melts. They can also occur when damns break.

How Are They Measured?
Floods are measured by stream gauges that are installed in and near bodies of water located near populated areas.

What Effects Do They Have?
Flooding can cause water damage to buildings, even destroying them if the current is strong enough. The flooding can also ruin plants, such as trees or crops on farm land. When flooding occurs, some people have to leave their homes and possessions behind to find high ground. Other people can't escape quick enough and get stuck. Sometimes animals may be harmed and might have to leave their habitats to get to safety.
Fantastic information Bryce! Those poor people in the photo with the water up to the roof of the house!

Cyclones are intense, spinning storm systems, with low pressure centers that can be vast in size. They form over warm oceans and can wreak havoc when they approach the shore. As the name suggests, tropical cyclones and hurricanes occur in the tropics. The center of a cyclone is called the eye and the wind spinning around it is called the eye wall an d sometimes if big enough the eye can be seen from satelites. Did you know that cyclones are sometimes named after men and women like cyclone Trevor and cyclone Veronica and pets!. cyclones are strong on the water but as they get onto the shore they grow weaker.
Good information, Jack! Can you find a picture to add.

Cyclones are large revolving tropical storms caused by winds blowing around a central area of low atmospheric pressure. Cyclones develop over warm waters in the tropical regions of the oceans where areas of very low pressure are created by air being heated by the sun.
Love the satellite photo. You can see why they call it the eye of the storm.

Floods are hydrological natural disaster. This means they are caused by the amount of water on the earth’s surface. Drought is another example of a natural disaster. Floods can happen suddenley or take days occur and can dissapear just as fast or slow. Storms, heavy rains and melting snow and ice are usually the reasons why floods occur. You should always avoid flood waters, even if they are only minor they are still very dangerous.
Good info Lachlan! I wouldn't want to be on that rubber ducky. You never know what's in flood water!

A drought is caused by drier than normal conditions that can eventually lead to water supply problems. Really hot temperatures can make a drought worse by evaporating moisture from the soil.

Types. People tend to define droughts in three main ways: Meteorological drought occurs when there is a prolonged time with less than average precipitation. Meteorological drought usually precedes the other kinds of drought. Agricultural droughts affect crop production or the ecology of the range.

There are four out of the many things that can cause a drought such as: 1)Land and water temperatures. 2) Air circulation and weather patterns. 3) Soil moisture levels. 4) Drought can also be a supply and demand of water issue.

How can we prevent droughts from happening: 1) Check your well pump periodically. 2) Plant native and/or drought-tolerant grasses, ground covers, shrubs, and trees, or small plants. 3) Install irrigation devices that are the most water efficient for each use, such as micro and drip irrigation, and soaker hoses. 4) Use mulch to retain moisture in the soil.

Droughts are a natural disaster that nobody can stop from coming, but we can prepare for the effects of this natural disaster to make it less difficult. There are many human and natural system impacts that this force of nature costs that we should be aware of.
What a lot of good information Lara! Good job!

Floods are caused by heavy rainfall, overflowing lakes, dams and rivers. If you are ever caught in a flood get to higher ground. Floods are a hydrological natural disaster. Never try to cross a flooded bridge or road even if it looks shallow there can be dangerous currents or debris that you cannot see.
Good info with lots of great technical words. Funny gif, poor guy!

Floods are the most frequent type of natural disaster and occur when an overflow of water submerges land that is usually dry. Floods are often caused by heavy rainfall, rapid snowmelt or a storm surge from a tropical cyclone or tsunami in coastal areas.
Good info Svend! I'll find a picture for you.
