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. 

3) Rainfall: 

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. 

5) Humidity: 

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.
