Question

define the monsoon and jet stream

Answer 1

The ridge of the jet lies over north-western India and is associated with strong divergence of winds and creates a high pressure region (sub-tropical high pressure belt) over entire north India. [ This is how the mechanism of jet streams influence Indian Monsoons in winter season]

Answer 2

→→→ The mechanism affecting the monsoon is that the westerly jet causes high pressure over northern parts of the subcontinent during the winter. This results in the north-to-south flow of the winds in the form of the northeast monsoon.

→→→ A jet stream is defined as a current of rapidly moving air that is usually several thousand miles long and wide but is relatively thin. They are found in the upper levels of Earth's atmosphere at the tropopause - the boundary between the troposphere and stratosphere (see atmospheric layers).

→→→ the seasonal wind of the Indian Ocean and southern Asia, blowing from the southwest in summer and from the northeast in winter. (in India and nearby lands) the season during which the southwest monsoon blows, commonly marked by heavy rains; rainy season.
