What air mass is represented by the letter c?
Air mass classification involves three letters. The first letter describes its moisture properties–“c” represents continental air masses (dry), and “m” represents maritime air masses (moist).
What does T stand for in air mass?
The first letter of the abbreviation (lowercase “m” or “c”) outlines weather the air mass is a dry, continental air mass or a moist, maritime air mass. The second letter in the abbreviation (capital “P”, “T” or “A”) gives an indication of the temperature of the air mass.
What are the 4 types of air masses?
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. Tropical air masses form in low-latitude areas and are moderately warm.
What are the 6 air masses?
This gives us six total types of air masses on Earth: maritime arctic (mA), maritime polar (mP), maritime tropical (mT); and continental arctic (cA), continental polar (cP) and continental tropical (cT).
What do the 4 letters stand for used in air mass classification c’m t p?
Classification of Air Masses
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.
What is polar air mass?
Polar air masses are those that form between latitudes 45°-75° north or south over the areas on which semi-permanent air heights are concentrated throughout the seasons of the year, such as the Siberian air high. The high temperature of the polar air mass that forms at the far north and far south poles.
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 air mass symbols?

| mT | the two-letter symbol used to indicate a warm air mass that formed over water |
| mP | the two-letter symbol used to indicate a cold air mass that formed over water |
| cT | the two-letter symbol used to indicate a warm air mass that formed over land |
What is air mass and its types?
Typically, there are 4 types of air masses:
- Arctic: These air masses form in the Arctic region and are very cold.
- Tropical: These air masses form in low lying latitudes and are warm up to a moderate level.
- Polar: These air masses form in the high-latitude region and are cold.
How many air mass types are there?
4 Types of Air Masses
Air masses can be further categorized based on whether they occur over water or land. The 4 types of air masses that impact North America most commonly are maritime tropical (mT), continental tropical (cT), maritime polar (mP), and continental polar (cP).
What are air masses 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.
What are the 4 fronts?
There are four different types of weather fronts: cold fronts, warm fronts, stationary fronts, and occluded fronts.
What are the symbols for fronts?
Symbols are used on surface weather maps to indicate the characteristics or type of front.
- A stationary front line is indicated by blue triangles on one side of the line alternating with red semi-circles on the opposite side of the line. …
- A cold front is a front that is moving in the direction of the warmer air.
What are air fronts?
A front is a weather system that is the boundary separating two different types of air. One type of air is usually denser than the other, with different temperatures and different levels of humidity. This clashing of air types causes weather: rain, snow, cold days, hot days, and windy days.
What defines 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 is mP air mass?
Maritime polar (mP) air masses are cool, moist, and unstable. Some maritime polar air masses originate as continental polar air masses over Asia and move westward over the Pacific, collecting warmth and moisture from the ocean.
How are air masses classified?
Air masses are commonly classified according to four basic source regions with respect to latitude. These are Polar (cold), Arctic (very cold), Equatorial (warm and very moist), and Tropical (warm).
