AN ANALOG THERMOMETER CONSISTS OF A SEALED GLASS TUBE WITH A METAL TIP.WHEN THE THERMOMETER COMES IN CONTACT WITH THE MATERIAL TO BE TESTED, THE MERCURY TURNS INTO LIQUID AND BEGINS TO RISE UP IN THE TUBE. THE POINT AT WHICH IT STOPS IS WHERE WE CAN TAKE THE TEMPERATURE READING ON THE SCALE. CELSIUS AND FAHRENHEIT ARE THE TWO COMMONLY USED UNITS FOR MEASURING TEMPERATURE. IN CELSIUS, THE FREEZING POINT IS 0 DEGREE CELSIUS AND BOILING POINT IS 100 DEGREE CELSIUS,WHEREAS IN FAHRENHEIT IT IS 32 DEGREE FAHRENHEIT AND 212 DEGREE FAHRENHEIT RESPECTIVELY.]]> 2018-09-02 07:12:18 UTC https://padlet.com/rajshreebhootra/measuringweather/wish/277127473 FORMULA FOR CONVERTING CELSIUS INTO FAHRENHEIT AND VICE-VERSA- rajshreebhootra https://padlet.com/rajshreebhootra/measuringweather/wish/277128227 C TO F: (C*9/5) +32=F

FOR EX.
IF THE TEMPERATURE IN CELSIUS IS 22 DEGREE CELSIUS THEN IT WILL BE :

THE ANEROID BAROMETER IS MORE CONVENIENT TO USE AS IT DOES NOT HAVE ANY LIQUID. IT CONSISTS OF A PARTIALLY VACUUM CHAMBER THAT EXPANDS AND CONTRACTS WITH CHANGING AIR PRESSURE.A BAROGRAPH CONSISTS OF A BAROMETER AND A PEN AT THE END OF THE POINTER,WHICH MOVES ALONG A ROTATING DRUM. BAROGRAPH IS USED IN METEOROLOGICAL OBSERVATORIES,WHILE MOUNTAIN CLIMBERS,SAILORS AND PILOTS USE ANEROID BAROMETER TO MEASURE AIR PRESSURE.MILLIBAR(mb) IS THE UNIT OF MEASUREMENT FOR AIR PRESSURE AND NORMAL AIR PRESSURE AT SEA LEVEL IS 1013.2 mb. THE AVERAGE AIR PRESSURE VARIES BETWEEN 940-1040 mb. JUST LIKE TEMPERATURE,IT VARIES WITH PLACE AND TIME.]]> 2018-09-02 07:54:47 UTC https://padlet.com/rajshreebhootra/measuringweather/wish/277129303 What is temperature and how to measure it? rajshreebhootra https://padlet.com/rajshreebhootra/measuringweather/wish/277218987 https://www.youtube.com/watch?v=J157oziu3zQ ]]> 2018-09-03 03:43:43 UTC https://padlet.com/rajshreebhootra/measuringweather/wish/277218987 THE BAROMETER AND HOW TO USE IT rajshreebhootra https://padlet.com/rajshreebhootra/measuringweather/wish/277219278 https://www.youtube.com/watch?v=EkDhlzA-lwI]]> 2018-09-03 03:47:17 UTC https://padlet.com/rajshreebhootra/measuringweather/wish/277219278 ANEMOMETER, WIND VANE AND WINDSOCK rajshreebhootra https://padlet.com/rajshreebhootra/measuringweather/wish/277219440 AN ANEMOMETER IS USED FOR MEASURING THE SPEED OF THE WIND AND THE WIND VANE IS USED TO MEASURE THE DIRECTION.AN ANEMOMETER CONSISTS OF FOUR CUPS THAT SPIN AROUND A VERTICAL POLE. IT RECORDS THE WIND SPEEDS IN "knots" OR kilometers per hour {km/hr}.
THE WIND VANE IS A MECHANICAL INSTRUMENT COMPRISING A FREELY MOVING ,ARROW SHAPED HORIZONTAL POINTER THAT POINTS TOWARDS THE DIRECTION FROM WHICH THE WIND BLOWS. SOMETIMES,WINDSOCK IS ALSO USED TO ASCERTAIN THE STRENGTH AND THE DIRECTION OF THE WIND. IT IS A CONICAL SHAPED CLOTH WHICH IS OPEN AT ONE END AND ATTACHED TO A POLE. WHEN THERE IS A STRONG CURRENT OF AIR, THE WINDSOCK GETS FILLED WITH AIR AND BILLOWS OUT IN THE DIRECTION OF THE BLOWING WIND. AN ANEMOGRAPH IS USED FOR CONTINUOUS MEASUREMENT AND RECORDING OF WIND SPEED ON A GRAPH PAPER.]]> 2018-09-03 03:48:55 UTC https://padlet.com/rajshreebhootra/measuringweather/wish/277219440 WIND SPEED AND DORECTION rajshreebhootra https://padlet.com/rajshreebhootra/measuringweather/wish/277221764 https://www.youtube.com/watch?v=SqbTrbxWT1o]]> 2018-09-03 04:06:51 UTC https://padlet.com/rajshreebhootra/measuringweather/wish/277221764 WIND VANE rajshreebhootra https://padlet.com/rajshreebhootra/measuringweather/wish/277221816 2018-09-03 04:07:17 UTC https://padlet.com/rajshreebhootra/measuringweather/wish/277221816 WINDSOCK rajshreebhootra https://padlet.com/rajshreebhootra/measuringweather/wish/277221865 2018-09-03 04:07:46 UTC https://padlet.com/rajshreebhootra/measuringweather/wish/277221865 HYGROMETER {PSYCHROMETER} rajshreebhootra https://padlet.com/rajshreebhootra/measuringweather/wish/277221995 HUMIDITY IS MEASURED WITH A HYGROMETER. THE PSYCHROMETER IS A TYPE OF HYGROMETER THAT USES TWO THERMOMETERS.IT HAS ONE WET BULB AND ONE DRY BULB THERMOMETER. IT MEASURES THE HUMIDITY THROUGH EVAPORATION.

THIS DEVICE CAN BE USED BOTH DURING THE DAY AND DURING THE NIGHT. IT THROWS AN INTENSE BEAM OF LIGHT TOWARDS THE CLOUDS . A REFLECTION OF THIS LIGHT FROM THE BASE OF THE CLOUD IS RECEIVED AT THE RECEIVER END, USING A CEILOMETER. WHEN THE REFLECTION IS DETECTED BY THE RECEIVER ,IT MEASURES THE VERTICAL ANGLE TO THE SPOT AND CALCULATES THE CLOUD THICKNESS.]]> 2018-09-03 04:15:33 UTC https://padlet.com/rajshreebhootra/measuringweather/wish/277222820 RAIN GAUGE rajshreebhootra https://padlet.com/rajshreebhootra/measuringweather/wish/277223728 A RAIN GAUGE IS AN INSTRUMENT FOR MEASURING RAINFALL. IT IS MEASURED IN millimeters{mm}. THE INSTRUMENT IS USUALLY INSTALLED IN AN OPEN SPACE AWAY FROM ANY OBSTRUCTION LIKE A TREE OR BUILDING. THE WATER IS COLLECTED IN A MEASURING JAR ANS THE READING IS TAKEN AT A FIXED TIME.
