Consider the following statements about the Jet streams in India :1. W...
Jet streams are fast-flowing, narrow meandering air currents in the atmosphere of the Earth. Jet streams are narrow belts of high altitude (above 12,000 m) westerly winds in the troposphere. Their speed varies from 110 km/h in summer to 184 km/h in winter. Tibetan highlands act as a barrier in the path of Western jet stream. As a result, jet streams get bifurcated. One of its branches blows to the north of the Tibetan highlands, while the southern branch blows eastward, south of the Himalayas. So, Statements 1 and 2 are correct.
An easterly jet stream flows over the southern part of the Peninsula in June and has a maximum speed of 90 km per hour. In August, it is confined to 15 degrees N latitude, and in September, up to 22 degrees N latitude. The easterlies normally do not extend north of 30 degrees N latitude in the upper atmosphere. The easterly jet stream steers the tropical depressions into India. These depressions play a significant role in the distribution of monsoon rainfall over the Indian subcontinent. These depressions' tracks are the areas with the highest rainfall in India. The frequency at which these depressions visit India, their direction, and their intensity all go a long way in determining the rainfall pattern during the southwest monsoon period. Westerly Jetstream brings the western cyclonic disturbances (originating over the Mediterranean Sea) that enter the Indian subcontinent from the west and the northwest during the winter months. An increase in the prevailing night temperature generally indicates an advance in the arrival of these cyclones' disturbances. Therefore, the jet streams impact monsoon onset, depending on the upper air circulation dominated by Sub Tropical Jet Streams (STJ). The southwest monsoon in India is directly related to the tropical easterly stream. So, Statement 3 is correct.

Western and Eastern Jet Streams in India
The jet streams are fast-flowing narrow air currents found in the atmosphere. In the context of India, both Western and Eastern jet streams play a significant role in influencing the weather patterns.
Western Jet Stream
- The Western jet stream flows from west to east in the upper troposphere.
- It is bifurcated by the Tibetan highlands, with one branch flowing north of the Himalayas and the other to the south.
Eastern Jet Stream
- The Eastern jet stream is located at a lower altitude compared to the Western jet stream.
- It flows from east to west.
Jet Streams in India
- India comes under the influence of both the Western and Eastern jet streams.
- The southern branch of the bifurcated Western jet stream plays a crucial role in determining the weather conditions in India.
- The Eastern jet stream also influences weather patterns in the region, albeit at a lower altitude compared to the Western jet stream.
Therefore, all the statements mentioned in the question are correct. India is impacted by the bifurcated Western jet stream, with the southern branch playing a significant role, as well as the Eastern jet stream, which influences weather patterns in the region.
