Question

How is the winter rainfall of the northwest part of India different from the winter rainfall of the southeast part of India?

Answer 1

HintThe winter rainfall in northwestern India is cyclonic in nature. When two masses of air of different temperatures, humidity, and density meet, cyclones are formed.

Complete step –by - step – solutionWinter precipitation in the north-western piece of India is caused because of western disturbance. It is useful for wheat crops in Punjab and Haryana.
In southeast India, the colder winter precipitation happens because of the withdrawing monsoon for example the Northeast monsoons. While moving over the Bay of Bengal, the breezes convey moisture and precipitate in the coastal areas of southeast India.

Additional information North east monsoon begins in mid-October caused by inversion of exchange winds. Exchange twists blow from the Siberian high while ignoring North Bay of Bengal, gets dampness and dumps as precipitation over the southern states like Tamil Nadu, Kerala, Andhra Pradesh, and Karnataka. Because of the upset climate movement over the Bay of Bengal, low-pressure systems generate and develop into cyclones which give most of the rainfall.
In North west India, post-monsoon, dry climate settles down predominantly. On occasion, a low-pressure system over the Mediterranean ocean in the west crosses east. At the point when this weather system reaches Northwest India; it rains as winter precipitation. Western slopes of the Himalayas get the majority of the precipitation out of this.

Note Western disturbance, explicitly the ones in winter, get moderate to hefty downpour in low-lying regions and weighty snow to hilly zones of the Indian Subcontinent. They are the reason for most winter and pre-monsoon season precipitation across northwest India.
