Classification of Air Masses
• Air masses are
classified according to the temperature and moisture characteristics of their
source regions.
• Bases on moisture
content: continental (dry) and maritime (moist)
• Based on
temperature: tropical (warm), polar (cold), arctic (extremely cold).
• Naming convention
for air masses: A small letter (c, m) indicates the moist content followed by
a capital letter (T, P,
A) to represent temperature.
