With reference to the mechanism of weather in the winter season in Ind...
- In winter months, the weather conditions over India are generally influenced by the distribution of pressure in Central and Western Asia. Hence statement 1 is correct.
- A high pressure centre in the region lying to the north of the Himalayas develops during winter.
- This centre of high pressure gives rise to the flow of air at the low level from the north towards the Indian subcontinent, south of the mountain range.
- The surface winds blowing out of the high pressure centre over Central Asia reach India in the form of a dry continental air mass.
- These continental winds come in contact with trade winds over northwestern India.
- The western cyclonic disturbances which enter the Indian subcontinent from the west and the northwest during the winter months, originate over the Mediterranean Sea and are brought into India by the westerly jet stream. Hence statement 2 is correct.
- All of Western and Central Asia remains under the influence of westerly winds along the altitude of 9-13 km from west to east. These winds blow across the Asian continent at latitudes north of the Himalayas roughly parallel to the Tibetan highlands. These are known as jet streams.
- Tibetan highlands act as a barrier in the path of these jet streams.
- As a result, jet streams get bifurcated and One of its branches blows to the north of the Tibetan highlands, while the southern branch blows in an eastward direction, south of the Himalayas. It has its mean position at 25°N in February at 200-300 mb level. Hence statement 3 is not correct.
- It is believed that this southern branch of the jet stream exercises an important influence on the winter weather in India

With reference to the mechanism of weather in the winter season in Ind...
The correct answer is option 'A' - 1 and 2 only.
Explanation:
Pressure Distribution in Central and Western Asia:
- The weather conditions over India are indeed influenced by the distribution of pressure in Central and Western Asia.
- The movement of air masses from these areas affects the weather patterns in India, especially during the winter season.
Western Cyclonic Disturbances:
- Western cyclonic disturbances play a significant role in bringing winter rains to India.
- These disturbances originate in the Mediterranean region and move eastwards towards the Indian subcontinent.
- They bring rainfall to various parts of North India during the winter months.
Jet Stream Interaction:
- The statement that the jet stream flowing south of the Himalayas merges with the one flowing north of the Tibetan highlands is incorrect. The jet stream actually flows from west to east.
- However, the jet stream does play a crucial role in influencing the winter weather in India.
- It helps in the formation and movement of weather systems, including western disturbances, which bring winter rains to the country.
In conclusion, statements 1 and 2 are correct as they accurately describe the mechanisms that influence the winter weather in India.
