How do we characterize an air mass that forms over the ocean?
Air masses that form over the ocean, called maritime air masses, are more humid than those that form over land, called continental air masses. For example, if an air mass forms over a tropical ocean, it is called maritime tropical. If an air mass forms over land in the far north it is called continental polar.
What are the air mass symbols?
With two terms for the humidity and four terms for the temperature, eight names are possible. These are: mE, mT, mP, mA, cE, cT, cP, cA (maritime equatorial, maritime tropical, maritime polar, maritime arctic, continental equatorial, continental tropical, continental polar, continental arctic).
What are the five air masses what are their characteristics?
Five air masses affect the United States during the course of a typical year: continental polar, continental arctic, continental tropical, maritime polar, and maritime tropical. Continental air masses are characterized by dry air near the surface while maritime air masses are moist.
What is the purpose of an air mass?
An air mass forms whenever the atmosphere remains in contact with a large, relatively uniform land or sea surface for a time sufficiently long to acquire the temperature and moisture properties of that surface. The Earth’s major air masses originate in polar or subtropical latitudes.
What are the 2 most important properties of an air mass?
An air mass is a large body of air whose properties are similar. The most important properties are temperature and amount of water vapor.
How does air mass affect weather?
Air masses are usually classified according to their temperature and humidity. There are cold and warm air masses and humid and dry air masses. In the Spring and Summer, it is important to study these air masses because it is the clashing of these air masses that cause such turbulent weather during this season.
What is air Mass example?
Each of the air mass types produce different weather and can affect the earth’s climate for days or months.

What happens when 2 air masses collide?
When two different air masses come into contact, they don’t mix. They push against each other along a line called a front. When a warm air mass meets a cold air mass, the warm air rises since it is lighter. As air masses move, pushed by winds, they directly influence the weather in the regions over which they pass.
What are the major air masses that influence the weather?
Four major types of air masses influence the weather in North America: Maritime Tropical (mT) Maritime Polar (mP) Continental Tropical (cT)
What is the relationship of air masses to a front?
An air mass is a body of air with a relatively constant temperature and moisture content over a significant altitude. Air masses typically cover hundreds, thousands, or millions of square kilometers. A front is the boundary at which two air masses of different temperature and moisture content meet.
What three types of air masses are needed to form a tornado?
Most tornadoes form from thunderstorms. You need warm, moist air from the Gulf of Mexico and cool, dry air from Canada. When these two air masses meet, they create instability in the atmosphere. PLEASE MAKE BRAINLIEST!
