An air mass is a large body of air with relatively uniform temperature and humidity characteristics. It forms over a source region and can influence weather conditions as it moves.
Air MassAn air mass is a vast volume of air in the atmosphere that has fairly consistent properties of temperature and humidity horizontally. It originates over a particular region known as the source region.Source Regions:- Polar regions can give rise to cold air masses. These air masses are characterized by low temperatures. For example, the Arctic air mass brings frigid conditions during winter to areas it moves over.- Tropical regions are the source of warm air masses. The air in these masses is relatively warm and moist, which can lead to humid and sometimes rainy weather when they move into other areas.Movement and Influence:As air masses move, they carry their temperature and humidity properties with them. When a cold air mass meets a warm air mass, it can cause significant weather changes. This interaction often leads to the formation of fronts, which are boundaries between different air masses. These fronts can bring storms, changes in wind direction, and shifts in temperature and precipitation patterns.
