Western Disturbance causes rain and snowfall in Northeast India, but what actually is the phenomenon?
The winds from the Sea: During the winter season, Western Disturbance brings cold winds from the Mediterranean Sea due to a low-pressure area over the water.
Travels west to east: From there they move from west to east, stopping to cause snowfall and rain due to the height of the Himalayas.
The swirling cyclone winds: An anticyclonic circulation of winds is formed which changes the wind direction from west to East, causing temp. increase in plains.
A chilling and dramatic exit: The disturbance stops changing the wind direction from east to west, chilling the plains again.
In simple terms, Western Disturbance is a storm that occurs during the winter season in the northern areas of the Indian subcontinent.
