What are 2 conditions you need for air mass formation?; What are the 3 required characteristics of air masses?; What are the two moisture properties used for air mass classification?; What are the 4 characteristics of air masses?

Answer :

Air masses form over large surfaces with uniform temperatures and humidity, called source regions

Air Masses: It is defined as a large volume of air in the atmosphere which contains mostly uniform temperature and moisture.

Air masses are classified according to the temperature and moisture characteristics of their source regions.

  • It has nearly uniform conditions of temperature and humidity at any given level of altitude.
  • When winds move air masses, they carry their weather conditions from the source region to a new region.
  • Maritime air masses form over the water and are humid. Continental air masses form over land and are dry.
