Why Delhi Drenched: On the morning of 28 June, Delhi-NCR received such heavy rainfall that all records were broken. The Meteorological Department said that after 88 years, so much rainfall was recorded in a single day. After this, claims started being made that perhaps a cloud burst in Delhi, that is why there was so much rain. Some political parties and government departments also tried to escape from this. But now the Meteorological Department has told the truth. Told why there was so much rain in Delhi-NCR at the same time?

IMD chief Mrityunjay Mahapatra clarified that the torrential rain in Delhi last week was not caused by cloudburst. Mahapatra said, these incidents cannot be called cloudburst, but it was similar to a cloudburst. Behind this incident is a strange change in the weather, which is known as Mesoscale Convective Activity.
What is this Mesoscale Connective Activity?
You can think of Mesoscale Connective Activity as a small storm. When a large-scale monsoon weather system creates a pressure area, which leads to strong storms and heavy rains. You can call it a cyclonic vortex of a storm. Sometimes it can last for 12 hours. Similar conditions were created in Delhi-NCR that day, and due to this there was a strong storm and rain in the morning. Usually, big storms are born from such conditions. Such conditions are created in tropical cyclones.
Three times more than the average rainfall
The IMD chief said that on that day, 91 mm rainfall was recorded in Safdarjung between 5 am and 6 am. The Lodhi Road weather station recorded 64 mm rainfall from 5 am to 6 am and 89 mm rainfall from 6 am to 7 am. In Safdarjung, 228.1 mm rainfall was recorded in just 24 hours, which is three times more than the average rainfall of June.
Then the forecast will be more accurate
Usually, on an average, only 74.1 mm of rain falls in June. This is the first time since 1936 that so much rain has been recorded. According to the IMD, rainfall between 124.5 to 244.4 mm in a day is called very heavy rainfall. Mahapatra also said that Delhi-NCR will get three more radars in the next two years, which will make the weather forecast more accurate. We are also working on a flood warning system for the capital.
