Question

what causes rainfall during winter in north-western part of India.

Answer 1

Answer:

Western disturbances cause rainfall during winter in the north western part 

Answer 2

Answer:

During the winter season, north-east trade winds prevail over India. They blow from land to sea and hence, for most part of the country, it is a dry season. These cause winter rains over the plains and snowfall in the mountains. It is because in this region these winds blow from sea to land, thereby carrying moisture along with them.
