A cold air mass originates over water or land that is colder than the air temperature at the time. Cold air masses usually originate in the northwest and travel eastward. A warm air mass is formed from warm water or ground temperature that is warmer than the air at the time. Warm air masses usually originate in the southwest and travel east or northeast.

Why is the US not a great place for air masses to form?

The US is not a great place for air masses to form because it is surrounded by oceans on three sides, which limits the development of continental air masses. In addition, the complex topography and variability of the climate in the US make it difficult for stable air masses to form and persist over large areas.

Is it true that Air masses that form near the equator are tropical air masses?

Yes, air masses that form near the equator are termed tropical air masses due to their warm and humid characteristics. They are typically stable and bring warm weather to many regions.


How are air masses that form land different from air masses that form over water?

These air masses are different due to their temperatures. Air masses over water tend to be bigger because of faster evaporation and faster condensation. I hope I helped! I'm covering this subject in science.


Scientists classify air masses according to?

In addition to their overall temperature air masses are classified according to the surface over which they form. continental air masses form over land, and are likely to be dry. Maritime air masses form over water and are humid. Polar air masses form at high altitudes and are cold. Tropical air masses form at low latitudes and are warm
