What are the properties of an air mass?

Air masses have fairly uniform temperature and moisture content in horizontal direction (but not uniform in vertical). Air masses are characterized by their temperature and humidity properties.

What type of air mass will be created if a batch of air sits over the equatorial Pacific Ocean for a few days?

The type of air mass that is created when a batch of air sits over the ocean in the equatorial region is called “Maritime Equatorial”. The symbol for this type of air mass is “mE”, where m stands for Maritime while E indicates the zone (Equatorial).

What happens to air masses as they travel?

Moving air masses cause the weather to change when they contact different conditions. For example, a warm air mass moving over cold ground may cause an inversion. Cold air masses tend to move toward the Equator. Warm air masses tend to move toward the poles.

What does an air front often cause 2 things?

Many fronts cause weather events such as rain, thunderstorms, gusty winds, and tornadoes. Usually the skies clear once the front has passed. A weather front is a border between two different air masses at the Earth’s surface. Each air mass has its own characteristics such as temperature and humidity.

What direction do occluded fronts move?

This forms an occluded front, which is the boundary that separates the new cold air mass (to the west) from the older cool air mass already in place north of the warm front. Symbolically, an occluded front is represented by a solid line with alternating triangles and circles pointing the direction the front is moving.

How does the occlusion of a polar front depression occur?

If a fast-moving cold air mass overtakes a slower-moving warm front and then continues advancing and catches another cold front, an occluded front forms. Weather associated with the occluded front is similar to the weather associated with a cold front.

What is a surface depression?

In geology, a depression is a landform sunken or depressed below the surrounding area. Depressions form by various mechanisms. River valley: a depression carved by fluvial erosion by a river. Area of subsidence caused by the collapse of an underlying structure such as sinkholes in karst terrain.
