Mid Latitude Cyclones Flashcards
Air mass
A huge mass of air, extending for hundreds of kilometres, with similar temperature and humidity
Backing
Change in the direction of the winds in an anticlockwise direction, for example from northwest to southwest
Cold front
The Boundry zone between a cold air mass and a warm air mass. Wind in the cold sector blow against the cold front.
Cold front occlusion
And inclusion with the overtaking call is colder than the cold air ahead of it
Cold sector
The area on the ground affected by cold air in MLC
Cold snap
A relatively short period of unusually cold weather
Cyclogenesis
The development and strengthening of a cyclone
occlusion
A late stage in the development of a mid-latitude cyclone where the cold air front to the rear catches up with the leading warm front, lifts the warm air off the ground, and meets the cold air ahead of the warm front.
Polar front
A zone where the cold polar air mass and warm subtropical air masses meet
Veering
A change in direction of winds in a clockwise direction, for example from northwest to southwest.
Warm front
The border zone between a warm air mass and a cold air mass. Winds in the warm sector blow against the warm front.
Warm front occlusion
An occlusion where the overtaking cold air is warmer than the cold air ahead of it
Warm sector
The area on the ground affected by warm air in a MLC
