Answer 1

Answer:

Jet streams are the air currents found in the highest part of the atmosphere. 1. The jet streams impact the onset of monsoon which depends upon the upper air circulation dominated by SubTropical Jet Streams (STJ). The south west monsoon in India is directly related to the tropical easterly stream.

Answer 2

• It is believed that the southern branch of the jet stream in northern hemisphere exercises an important influence on the winter weather in 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.

• The Sub-Tropical Jet stream plays a significant role in both hindering the monsoon winds as well as in quick onset of Indian monsoons.

The burst of monsoons depends upon the upper air circulation which is dominated by Sub Tropical Jet Streams (STJ).
