Winter season is experienced in India from December to February. India experiences winter season when the sun is in the southern hemisphere. North India experiences severe cold during this time. This is because temperature decreases from south to north. During this season, days are generally warm and nights are severely cold in North India. Snowfall is a common phenomenon in hill stations like Manali and Shimla.
The phenomenon of western disturbance is another feature of the cold season; Cyclones originating in the Mediterranean Sea in winter travel eastwards and enter India. This causes winter rainfall in North Indian plains, especially in Punjab region. This is known as western disturbance. This rainfall is very beneficial for rabi crops. Jet streams bring western disturbance to India.
