Answer 2

The temperature ranges between 10°-15°C in the northern plains. The weather is usually marked by clear sky, low temperatures and low humidity and feeble variable winds.

The inflow of the cyclonic disturbances from the west and the northwest is a characteristic feature of the cold weather over the northern plains.

These low- pressure systems originate over the Mediterranean Sea and Western Asia and move into India. They cause winter rains over the plains and snowfall in the mountains.
