Which of the following reasons may be attributed to excessive cold in ...
There are three main reasons for the excessive cold in north India during the winter season :
  • Continentality- States like Punjab, Haryana and Rajasthan being far away from the moderating influence of sea experience continental Climate.
  • The snowfall in the nearby Himalayan ranges creates a cold wave situation.
  • Around February, the cold winds coming from the Caspian Sea and Turkmenistan bring cold wave along with frost and fog over the northwestern parts of India.
  • The easterly jet stream sets in along 15°N latitude only after the western jet stream has withdrawn itself from the region,i.e.around June. This easterly jet stream is held responsible for the burst of the monsoon in India. It does not play a role in an extremely cold climate in North India during the winter season.
Hence, all the options are correct.

Reasons for Excessive Cold in North India During Winter Season:

1. Continentality of the North Indian Region:
The North Indian region is landlocked and far away from the moderating influence of the sea. This results in a large diurnal temperature range, with temperatures dropping rapidly at night due to lack of moisture in the air.

2. Snowfall in the Himalayan Ranges:
The Himalayan ranges receive heavy snowfall during the winter season, which contributes to the cold weather in the region.

3. Cold Winds Coming from the Caspian Sea:
During winter, cold winds blow from the Caspian Sea towards North India, which further lowers the temperature in the region.

4. Early-Onset of Easterly Jet Streams:
The easterly jet streams are strong winds that blow from east to west in the upper troposphere. During the winter season, these jet streams tend to shift southwards earlier than usual, resulting in colder temperatures in North India.

Conclusion:
All of the above reasons contribute to the excessive cold in North India during the winter season. The combination of these factors makes the region one of the coldest in the country.
