What is an air mass quizlet?
Air Mass. An air mass is a huge body of air in the lower atmosphere that has similar temperature,humidity, and air pressure at given height.
How are air masses classified quizlet?
Air masses are classified by temperature (polar or tropical) and the surface (continental or maritime) over which they form.
How does air mass form quizlet?
Air masses are formed by uneven heating and cooling of the Earth by the sun. This causes pressure differences in different areas of the globe. The movement of air masses is just the flow of high pressure air masses to low pressure areas.
On what basis is an air mass classified?
Air masses are classified according to the temperature and moisture characteristics of their source regions. Based on temperature: tropical (warm), polar (cold), arctic (extremely cold).
What is the definition for an air mass?
An air mass is a large volume of air in the atmosphere that is mostly uniform in temperature and moisture. Air masses can extend thousands of kilometers in any direction, and can reach from ground level to the stratosphere—16 kilometers (10 miles) into the atmosphere.
What are the 5 types of air masses?
The air masses in and around North America include the continental arctic (cA), maritime polar (mP), maritime tropical (mT), continental tropical (cT), and continental polar (cP) air masses.
What are the 4 types of air mass?
Meteorologists identify air masses according to where they form over the Earth. There are four categories for air masses: arctic, tropical, polar and equatorial. Arctic air masses form in the Arctic region and are very cold.
What are air masses answer?
What is an air mass answer? An air mass is a large volume of air in the atmosphere that is mostly uniform in temperature and moisture. Air masses can extend thousands of kilometers in any direction and can reach from ground level to the stratosphere—16 kilometers (10 miles) into the atmosphere.
Is an air mass?
An air mass is a large body of air with generally uniform temperature and humidity. The area over which an air mass originates is what provides its characteristics. The longer the air mass stays over its source region, the more likely it will acquire the properties of the surface below.
What are the 4 types of air masses?
When the air mass reaches a new region, it might clash with another air mass that has a different temperature and humidity. This can create a severe storm. Meteorologists identify air masses according to where they form over the Earth. There are four categories for air masses: arctic, tropical, polar and equatorial.
What are the 5 air masses?
The air masses in and around North America include the continental arctic (cA), maritime polar (mP), maritime tropical (mT), continental tropical (cT), and continental polar (cP) air masses.
What are examples of air mass?
In North America, for example, cold and dry air covering thousands of miles flows south from the Arctic, especially in winter, and warm moist air flows north from the Gulf of Mexico. These different types air are called air masses. An air mass is like a team whose players are all wearing the same uniform.

What are the 6 types of air masses?
On Earth, air masses form in different regions over land and water. The six main air masses are continental arctic, continental polar, maritime arctic, maritime polar, continental tropical, and maritime tropical.
What are the 5 types of air mass?
These are Polar (cold), Arctic (very cold), Equatorial (warm and very moist), and Tropical (warm). In the United States the major air mass types are typically continental Polar, maritime Polar, continental Tropical, and maritime Tropical.
