Answer 1

A Western Disturbance is an extratropical storm originating in the Mediterranean region that brings sudden winter rain to the northwestern parts of the Indian subcontinent.[1][2] It is a non-monsoonalprecipitation pattern driven by thewesterlies. 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 counterparts where the moisture is carried in the lower atmosphere. In the case of the 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]
