Air Mass is a volume of air characterized by temperature and water vapor content and stretched for 100 kilometers.
Classified according to the latitude and the source regions, like cold air mass found in cooler polar regions and warm masses form over the hotter and drier regions of continents and maritime air mass are found at the seas and oceanic masses.
As air mass differs based on there densities they have humid and temperature conditions and can be modified in various ways, an increase or decrease of temperature is also affected by the large scale environmental conditions.
