Question

name the winds that bring rain to North Western India in winter.

Answer 1

North East Monsoon does that. South West Monsoon passes by & it only rains in some areas scantily.

Answer 2

A Western Disturbance is an extratropical storm originating in the Mediterranean regionthat brings sudden winter rain to the northwestern parts of the Pakistan’s western parts.[1][2] It is a non-monsoonal precipitation pattern driven by the westerlies. The moisture in these storms usually originates over the Mediterranean Sea and the Atlantic Ocean.[3]Extratropical storms are a global phenomena with moisture usually carried in the upper atmosphere, unlike their tropical counterpartswhere the moisture is carried in the lower atmosphere. In the case of the Indian subcontinent, moisture is sometimes shed as rain when the storm system encounters the Himalayas.

Western Disturbances are important for the development of the Rabi crop, which includes the locally important staple wheat.[4][5]
