Why temperate cyclones occur in winter?

Where does temperate cyclones occur?

Location: Temperate cyclones exhibts wide variety of characteristics. They are formed between to 35˚ to 65˚ north and south latitudes in the sub-polar frontal zone and this is a result of interaction between cold polar mass and warm tropical air masss in the westerly wind belt.

How does the temperate cyclone influence the winter climate of India?

Temperate cyclone also known as depressions, enter India from the Mediterranean Sea in the cold season. B. These cause winter rains over the Northern plains and snowfall in the mountains.

Where do temperate cyclones occur in India?

They are the cause of the most winter and pre-monsoon season rainfall across North-West India (such as Punjab, Haryana, Delhi and western Uttar Pradesh). Temperate cyclones, specifically the ones in winter, bring moderate to heavy rain in low-lying areas and heavy snow to mountainous areas of the Indian Subcontinent.

How are temperate cyclones formed Upsc?

The warm air climbs over the cold air and a series of clouds appear over the sky ahead of the warm front and cause rainfall. The cold front approaches the warm air from behind and pushes the warm air up. As an outcome, cumulus clouds develop along the cold front.

What is the difference between temperate and tropical cyclone?

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. … Temperate cyclones do not become weak like Tropical cyclones on reaching the land.

What is difference between tropical cyclone 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.

Why do cyclones occur mostly in late summers?

cyclones occur mostly in late summers because : Due to high specific heat of water, and mixing, the ocean waters in northern hemisphere attain maximum temperatures in August (in contrast continents attain maximum temperatures in June-July).

Why do cyclones develop in late summer?

Tropical cyclones in the Atlantic Basin are most numerous during late summer and early autumn because that is the time of year when the two most important ingredients needed for their formation — warm ocean waters (80 degrees or higher) and weak vertical wind shear (little change in wind direction and/or speed with …
