How temperate cyclones are formed?

Temperate cyclones form when two opposing air masses collide, such as light tropical air masses and thick polar air masses. Temperate cyclones are also known as Extra-tropical cyclones.

What is structure of temperate cyclone?

The temperate cyclones are asymmetrical and shaped like an inverted ‘V’. They stretch over 500 to 600 km. They may spread over 2500 km over North America (Polar Vortex). They have a height of 8 to 11 km.

What are the main characteristics of temperate cyclones?

Characteristics of Temperate Cyclone

  •  The temperate cyclone moves counter clockwise in northern hemisphere and clockwise in southern hemisphere.
  •  It may be 1600km wide, thus a single cyclone may cover the whole Europe.
  •  The isobars are elliptical in shape.
  •  The cold air mass moves faster than the warm air mass.

What are the temperate cyclones?

Temperate Cyclone (Extratropical Cyclones) [NCERT Notes For Geography UPSC] Temperate cyclones are also known as Extra-tropical cyclones where the term “Extra-tropical” signifies that this type of cyclone generally occurs outside the tropics with a latitude range between 30° and 60°.

What is the difference between tropical cyclones and temperate cyclone?

Temperate cyclones are cold cored, and winds increase with height. Tropical cyclones have much more intense rainfall that temperate cyclones, since deep convection is their source of energy. Temperate cyclones tend to have more moderate rainfall, although in extreme cases still enough to cause destructive flooding.

How many types of temperate cyclones are there?

A temperate cyclone is referred as mid-latitude depressions, extra-tropical cyclones, frontal depressions and wave cyclones. Temperate cyclones are active above mid-latitudinal region between 35o to 65o latitudes in both hemispheres.

What is the difference between tropical and temperate cyclones?

Tropical cyclone develops in the Inter tropical convergent zone. They are formed due to the differential heating of land & Sea. Temperate cyclones are formed along a front, where hot and cold air masses meet. They often cause heavy loss of life and property on the coasts and become weak after reaching the land masses.

How cyclones are formed?

The cyclone is formed when the warm, moist air rises upward over the ocean. As this air moves up, there is a formation of a low-pressure area below. Now the low-pressure area is filled with the high-pressure air from the surroundings. Again, the next batch of cool air gets warm and moist over the ocean moving upward.

What is the major difference between tropical and temperate cyclone in terms of their heat characteristics?

Why do temperate cyclones move from west to east?

Temperate cyclones form along the polar front. The Temperate cyclones are under high influence of permanent winds called westerlies in the middle latitude between 30 and 60 degrees latitude, due to these winds temperate cyclones move from west to east with these westerlies.

What is cyclone formation?

Cyclone is system of winds rotating inwards at a high speed with the area of low pressure in the middle. Tropical cyclones are formed only over warm ocean waters near the equator. When warm, moist air over the ocean rises upward from near the surface, a cyclone is formed.
