Direct Reading air Mass Flashcards
The region along where receives more solar energy in the polar regions do?
Equator
Heated equatorial Air rises and creates a center of?
Low pressure
Cold Air near the poles sink in create centers of?
High pressure
Air moves from?
Areas of high-pressure to areas of low pressure
There is a general worldwide movement of air from?
Poles towards the equator
What happens to the air when the air pressure differences are small
The Air remains stationary. If the air remains stationary or moves slowly over a uniform region, it takes on the characteristic temperature and humidity of that region.
What is an Air mass?
A large body of air throughout which temperature and moisture content are similar
What are the characteristics of air masses that form over polar regions
They are very cold and dry
What are the Characteristics of air masses that form over tropical oceans
They are warm and moist
Differences are caused by equal unheating of earths surface is by what?
Air pressure
