Humidity

•   Humidity is the measure of how wet the air is, i.e. amount of water present in the air. 
•   More the amount of water in the air, the higher will be humidity, less water Low humidity
•   Humidity is measured using Hygrometer.

 Humidity can be expressed in various forms, like Absolute Humidity, Relative Humidity, and Specific Humidity.

1.   Absolute Humidity = Mass of water vapor per volume (or mass) of moist air.
2.   Relative Humidity (%) = (water vapor present in air/maximum possible water which air can hold) × 100
3.   Specific Humidity = Mass(Volume) of water vapor present per unit Mass(Volume) of air.

•   We usually talk about relative humidity as it is a more practical measure of atmospheric moisture. 
•   Air containing moisture to its full capacity at a given temperature is said to be Saturated.
•   Humidity near an ocean or coastal region can be high due to its proximity to water bodies.
•   With Height (altitude) the capacity of air to hold water decreases.
•   Temperature and humidity share an inverse relationship.  

•   Humidity changes with time in a day, It’s high in the morning, then keep decreasing till noon, and then increases again.  
•   Humidity is affected by Temperature, water body, and air movement.

Here we are going to discuss “Humidity and Precipitation”. It is a part of environmental studies of the General Awareness section of many competitive exams. Kindly bookmark this article for future reference.
