What are characteristics of air masses?
- Air Mass is an extremely large body of air whose properties of temperature and moisture content (humidity), at any given altitude, are fairly similar in any horizontal direction.
- Source Regions are simply geographic areas where an air mass originates.
- cP continental polar cold, dry, stable.
What are the four air mass types and what are their major characteristics?
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. Polar air masses take shape in high-latitude regions and are cold.
How do warm and cold fronts differ?
A cold weather front is defined as the changeover region where a cold air mass is replacing a warmer air mass. A warm weather front is defined as the changeover region where a warm air mass is replacing a cold air mass.
What are two characteristics are used to classify air masses?
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 characteristics give warm fronts and cold fronts their names?
There are four types of fronts, three moving and one stationary. With cold fronts and warm fronts, the air mass at the leading edge of the front gives the front its name. In other words, a cold front is right at the leading edge of moving cold air and a warm front marks the leading edge of moving warm air.
What are the 3 characteristics of air?
The properties of air are:
- Air takes up space.
- Air has mass.
- Air is affected by heat.
- Air exerts pressure.
- Air can be compressed.
- Air is affected by altitude.
What are three characteristics of air mass?
Continental air masses are characterized by dry air near the surface while maritime air masses are moist. Polar air masses are characterized by cold air near the surface while tropical air masses are warm or hot. Arctic air masses are extremely cold.
