What are western disturbances? How do they affect india's climate?

Answer 1

Answer:

western disturbance

The extratropical storm originating in the Mediterranean region that brings sudden winter rain to the north-western parts of the Indian sub-continent is called Western Disturbance. It is a non-monsoonal precipitation pattern driven by the westerlies.

Impact of Western Disturbance on the Indian Sub-continent

Western Disturbance plays important role in bringing moderate to heavy rain in low-lying areas and heavy snow to mountainous areas of the Indian Subcontinent especially in winter. This disturbance is usually associated with cloudy sky, higher night temperatures and unusual rain. This precipitation has great importance in agriculture, particularly for the Rabi crops. Wheat among them is one of the most important crops, which helps to meet India’s food security.
