Answer using full sentences, IQIA. Objective: I can understand that weather changes as air masses move Please have on desk: 17.1 RSG

2. Weather Changes As Air Masses Move

3. Air Masses Are Bodies of Air That Move Through The Atmosphere Air Mass – A large volume of air in which temperature and humidity are nearly the same in different locations at the same altitude. An air mass forms when the air over a large region of Earth sits in one place for many days. The air gradually takes on the characteristics of the land or water below it. Earths surface can affect the air on Earth.

4. The Four Types of Air Masses Continental air masses form over land. Air becomes dry as it looses moisture. Maritime air masses form over water. Air becomes moist as it gains water vapor. Tropical air masses form near the equator. Air becomes warm as it gains energy from the warm land or water below. Polar air masses form far from the equator. Air becomes cool as it loses energy from the cold land or water below.

5. How Air Masses Move Air masses can travel away from the regions where they form. They move with the global pattern of winds. When an air mass moves to a new region, it carries along its characteristic moisture and temperature.

6. Cold Front Front – A boundary between air masses. Cold fronts can move into regions quickly. A front is steeper then any other fronts. Cold fronts often produce cumulonimbus clouds, which can cause heavy storms. Cold Front

7. Warm Front Warm fronts move more slowly than cold fronts. Warm air moves up and over a mass of denser and colder air. As a warm front approaches, you may first see high cirrus clouds, then stratus clouds, then lower stratus clouds. Often a warm front brings many hours of steady rain or snow. Warm Front

8. Stationary Front Stationary fronts occur when air masses first meet or when a cold or warm front stops moving. For a while the air masses stay in the same location. If the air pushes up it may produce clouds that cover the sky. Stationary Front

9. Pressure Systems High-pressure system is formed when air moves all the way around a high-pressure center. Generally brings clear skies and calm air or gentle breezes. Low-pressure system is a large weather system that surrounds a center of low pressure. Usually develops between a warm air mass and a cold air mass.
