Date: 22 May 2021 Tags: Miscellaneous

Issue

National capital Delhi has witnessed a record rainfall in the past few days. It has been attributed to convergence of Western Disturbance and Cyclone.

 

Background

India has seen emergence of a high intensity Cyclone few days back, that has travelled up to the northern plains including Delhi.

 

Details

  • The Western disturbance, a non-monsoon weather pattern was moving towards Delhi from the Western Himalayas.

  • The convergence of this with the Cyclonic weather caused the rains to lash out at the Capital. This led to various weather related problems.

 

Rains in Delhi

  • Delhi receives rainfall during monsoon. Its intensity varies but is mostly moderate. It also sometimes receives pre-monsoon showers.

  • The cyclone arriving at the same time during western disturbance is very rare. This phenomenon took place and led to the record rains.
