This energy fuels the Earth's weather system.
How much incoming solar radiation is received by the Earth is controlled by four factors :
1. The solar constant (energy released by the sun)
2. The distance of the Earth from the sun
3. Altitude of the Sun
4. Length of Night and Day]]> 2016-08-02 11:44:07 UTC https://padlet.com/bryanhariadi/ewolakro2kni/wish/117366259 Reflected Solar Radiation (Albedo) bryanhariadi https://padlet.com/bryanhariadi/ewolakro2kni/wish/117367663 As the radiation from the Sun passes through the atmosphere, some is absorbed by liquids, gases and solids. Some is reflected and scattered, especially by the tops of clouds. The amount of energy that is reflected by a surface is determines by the reflectivity of that surface, called the albedo.

Albedo is expressed as a percentage. A high albedo means the surface reflects the majority of the radiation that hits it and absorbs the rest. A low albedo means a surface reflects a small amount of the incoming radiation and absorbs the rest.

Example: Fresh snow reflects up to 95% of the incoming radiation.

  • The atmosphere has an energy budget.
  • It receives energy from the sun and the earth (inputs)
  • It looses energy to space (outputs)
  • If it looses more energy than it gains the atmosphere cools down
  • If it gain more energy than it looses it heats up

  • Energy received by the earth is converted into heat energy when it reaches the surface. As the ground warms, some is re-radiated as long wave radiation.
  • 8% of this re-radiated energy is lost to space
  • Evaporation and condensation account for a loss of 25 % of the heat energy from the earth as heat energy is used up when liquid is turned into vapour (this is called latent heat transfer)
  • 7% of this re-radiated energy is absorbed by clouds, water vapour and CO2

  • Energy arriving at the surface has the potential to heat that surface, as heat is absorbed by it.
  • The nature of the surface has an effect, e.g. If the surface can conduct heat rapidly   into the lower layers of the soil its temperature will be low. If the heat is not carried away quickly it will be concentrated at the surface & result in high temperatures there.

  • This is emitted by the surface, and passes into the atmosphere, and eventually into space.
  • There is also a downward-directed stream of long-wave radiation from particles in the atmosphere
  • The difference between the 2 streams is known as the net radiation balance.
  • During the day, since the outgoing stream is greater than the incoming one, there is a net loss of energy from the surface.

    e.g. Advection Fog: As warm, moist air passes over a cold surface it is chilled, and condensation takes place as the temperature of the air is reduced and therefore it reaches dew (saturation) point)

    e.g. Radiation Fog: Occurs when the ground loses heat at night by long wave radiation and therefore the air above it is cooled causing condensation and fog.

    2) More water vapour must have been added to the atmosphere close to the ground.

The land is heated quicker than the sea and so the air above the land is warmer than the air above the sea during the day.

    As air above the land surface is heated by radiation from the Sun, it expands and begins to rise, being lighter than the surrounding air. To replace the rising air, cooler air is drawn in from above the surface of the sea. This is the sea breeze, and can offer a pleasant cooling influence on hot summer afternoons.

This creates a situation which is the opposite to day time – where the air above the sea is actually warmer at night than the air above the land. In this case, it is air above the warmer surface water that is heated and rises, pulling in air from the cooler land surface.

This is an example of a sensible heat transfer. Sensible heat is the energy required to change the temperature of a substance with no phase change. The temperature change can come from the absorption of sunlight by the soil or the air itself. Or it can come in contact with the warmer air caused by release of latent heat (by direct conduction)

When heat is taken from the atmosphere to help with this process it will result in the atmosphere being cooled.

    When the process of evaporation is reversed, for example when water vapour is changed to water by condensation, heat energy is released into the atmosphere which will heat up as a result. The main processes that do this type of transfer are radiation, conduction, and convection.

    During the night, there is no incoming solar radiation, which means that only source of energy is the radiation that is being held/retained within the atmosphere. This main energy flow is therefore a new loss of heat from the land, which cools the air from the surface upwards.

    The amount of energy absorbed by the surface and sub-surface during daylight hours can be affected by a variety of factors, such as the presence of a large bodies of water and snow cover. These can have high albedo and reflect as much as 80-90% of the incoming radiation.

A light-coloured soil or rock, like chalk, is a poor conductor so heating will be confined to the surface; this explains the high temperatures of 50-60 centigrade recorded on hot deserts in daytime. In contrast, a dark volcanic soil or dark rocks like basalt and slate, with low albedos of 5-10 percent, will absorb heat well.
