Definition of Air Mass An air mass is a huge body of air having homogeneous temperature and moisture (humidity) condition over a large area. The properties of an air mass convey the climatic condition of its source region. There are different types of air masses based on source region. Source regions of air masses are … Read more
There is primarily three types of rainfall based on the means of condensation of moisture in the air. The rising hot air cools at dry adiabatic and wet adiabatic lapse rate which leads to condensation of water vapor present in rising air at high altitude. Subsequently, the condensed water droplets coalesce to form larger water … Read more
We need to understand different types of lapse rates to satisfy a curious person who might ask for the reason of rainfall. “Why does it rain?” To answer this simple question, we must understand that the temperature of air declines as it rises from the earth surface towards higher altitude. The curious mind will again ask, … Read more
What is Adiabatic change of temperature? The change in temperature of any parcel of air due to change in pressure is called adiabatic change in temperature. This change in temperature happens without exchange of heat of a given parcel of rising air with the surrounding air. Let’s disaggregate this concept First, Earth surface gets heated … Read more
