Fronts are associated with cyclones, or areas of low pressure, and occur when cold air masses meet warm ones (1). The circulation of the Earth's atmosphere causes the cold air to move eastwards and equatorwards (2) and the warm air to move eastwards and polewards in a wedge shape called the warm sector (3). This movement causes the front to buckle (4), with a warm front to the east, where the leading edge of the warm sector is replacing cold air, and a cold front to the west (5). Because cold air moves faster than warm air, the warm sector is gradually squeezed and the front occludes and decays (6).

Describe the conditions along a stationary front?
The weather associated with a stationary front is similar to that produced by a warm front. And a warm front generally brings drizzly precipitation. :)
Describe the weather before and after an occluded front?
The weather before an occluded front is usually warm and humid. After an occluded front, the air is typically drier and cooler.
Would you describe warm air mass?
no you would not describe a warm air mass cause you don't know where the warm air mass is and whether or not it is warm and if you can describe it.
Where does precipitation that is associated with a warm front typically arrive?
It arrives in front of the warm front
What happens when a warm front moves into a cold front?
warm front rises on top of the cold front.
What is the formation and type of clouds along a warm front?
It Cools as it is pushed upward.

Describe weather associated with a warm front?
It's cold?
A word to describe a mixed front of warm and cold air?
Occluded
How would you describe the cloud formation?
Clouds form when warm, humid air rises and cools to it's dew point.
What are the stages in the formation of an occluded front?
1. a cold front moves toward a warm front, forcing warm air aloft. 2. a cold front merges with the warm front to form an occluded front that drops heavy rains 3.because occluded fronts often move slowly, light precipitation can fall for several days
Describe the weather before and after an occluded front?
The weather before an occluded front is usually warm and humid. After an occluded front, the air is typically drier and cooler.
What is the term used to describe warm and cold air mass that meet but don't move?
Stationary front.
Named four types of fronts and describe the type of weather each bring?
The four types of fronts change the weather on Earth. A warm front brings warm, humid air and a cold front brings dry, cool air. A stationary front does not move and have winds parallel to the front. An occluded front occurs when cold air overtakes warm air.
What front is it called when a cold air mass catches up to a warm air mass?
When a cold air mass catches up to a warm air mass, it is called a cold front. At a cold front, the cold air replaces the warm air, creating a boundary between the two air masses. This can result in the formation of clouds, precipitation, and potentially severe weather.
Describe the four major types of fronts?
1) Warm front - warm air mass replacing a cold air mass at ground level. Typically shifts wind southeasterly to southwesterly. 2) Cold front - Cold air replacing warm air at ground level. Tyoically shifts southwesterly to northwesterly 3) Stationary front - Equal amount of energy between warm and cold air masses creating a "stalemate".
Would you describe warm air mass?
no you would not describe a warm air mass cause you don't know where the warm air mass is and whether or not it is warm and if you can describe it.
