Maximum and minimum temperature of a day, air pressure, rainfall, wind speed and humidity are called measuring components of weather.
1) Maximum and minimum temperature of a day:
Maximum and minimum tempera-ture of a day are the highest and lowest temperature recorded respectively during a day. Six’s maximum and minimum thermometer is one of the meteorological in-struments used to measure maximum (highest) and minimum (lowest) temperatures of a place in a day.
2) Air pressure:
The force applied by air on any surface in contact is called “air pres-sure”. Air pressure is measured in height of mercury level in centimeters and it is measured with a barometer.
The amount of water falling in rajn within a given time and area is called Rain fall. Rainfall is measured in millimeters by using a rain gauge.
4) Wind speed:
Wind move is caused by difference in the air pressure in two places. The speed of wind can be measured using a device called an anemometer.
The water vapour present in the air is called humidity Hygrometer is used to measure humidity in air and it is expressed in grams per cubic meter.
