Question

What is the impact of depressions or temperate cyclones on the general climate of North India?

Answer 1

Hint:
The temperate cyclone or depression happens in the area where the polar front where the hot westerlies and cold polar winds converge. Winds are incredible in a downturn and the blast spirally inwards in an anticlockwise way in the northern side of the equator.

Complete Answer:
When a regional low-pressure zone evolves around along the front, the front bubbles. It aspects within $30^\circ $ and $50^\circ $ latitude during winter months and rises into enormous spiralling storms which can be 1000 miles broad.
In the first stage, a boundary segregates the warm and cold fronts.
In the second stage, the front ranges into two, which are, the warm front where the warmer and thus brighter westerlies slide over the colder and hence heavier polar winds, and a cold front at the veneer of the polar winds where they undercut and push the lighter westerlies from the rear. The two fronts jointly segregate the air into a hot region where the hot air prevails and a cold area where the cold polar air predominates.
In the third phase, the polar air has attained in entirely hoisting the hot westerlies off the bottom from the bottom, creating the cold air predominating all over at ground level. This final phase of depression is named an occlusion.
Temperate cyclones are moreover named as westerly depressions. These make their origin in the Mediterranean Sea or the Atlantic Ocean which lies in the temperate zone. These cyclones walk east towards India under the effect of the westerly jet stream. These storms arise in rains in the northern states like Punjab and Kashmir in the winter.

Note:
Winds are powerful in a recession and the bang spirally inwards in an anticlockwise path in the northern hemisphere, towards the low pressure in the centre. In the southern hemisphere, they knock in a clockwise direction. It is hot in the warm sector, chill in the cold sector and rainy among both fronts.
