Thunderstorm helps lower Delhi’s rainfall deficit

With rain and a thunderstorm breaking long and mostly dry, the temperature in Delhi – NCR fell on Monday. The maximum temperature on Monday was 31.5 degrees Celsius, which is eight degrees below normal for this time of year.

And the lowest temperature in the early hours of Monday morning was 17.2 degrees Celsius, nine degrees lower than the normal, and the lowest level for the month of May since 2004, when the minimum temperature was recorded 16.7 degrees in May. The lowest minimum temperature was recorded in May 2021, 18 degrees Celsius, while it was 20 degrees in May 2020. The temperature began to drop on Monday morning, dropping from 29 degrees to 18 degrees between 5.40 am and 7 am. Strong winds of around 80 kmph were recorded over Delhi-NCR Monday morning.

According to IMD scientists, this was the first “moderate intensity” storm of the season. The Safdarjung Weather Observatory, which provides representative figures for the city, recorded 12.3 mm of rain between 5.30 am and 8.30 am on Monday. This helped cut the season’s deficit, said RK Jenamani, Scientist, Indian Meteorological Service (IMD). From February 25 to May 20, the weather station in Safdarjung recorded only 1.7 mm of rain, the lowest level for this period since 1945, according to Janamani. He added that in 1945 the same period did not record any rainfall at all.

The normal amount of precipitation for the season in Safdarjung is 41.6 mm. So far, the city has registered 15.6 mm, which is a shortfall of about 63%. From March to May, the normal occurrence of thunderstorms in Delhi is around 12 to 14 days, but this season only recorded four to five such days as of Monday, and most of them were dry, said Jinamani.

The maximum temperature at Gurgaon Weather Observatory dropped below 30°C and stabilized at 29.4°C. The minimum temperature was also low in Gurgaon, stabilizing at 16.5 degrees Celsius on Monday. Jinamani said southern Haryana, particularly Faridabad and Gurgaon, recorded heavy rains on Monday. Gurgaon recorded about 73.4 mm of rain. In Delhi, Aya Nagar meteorological station recorded the highest amount of 52.2 mm on Monday, while Palam recorded 27.6 mm.

The downpour was caused by an active western disturbance that began affecting parts of Punjab on Sunday night, then clouds moved towards Haryana and Delhi, before turning east to Uttar Pradesh, Jinamani said. The height of the thunderstorm and precipitation activity was seen on Monday morning, but the cloudy weather will continue until Monday evening or Tuesday morning, according to Janmani. He added that the effect of the thunderstorm could mean heat wave conditions are likely to remain subdued until May 29 or 30.

A bulletin from the International Institute for Democracy (IMD), released on Monday evening, stated that western disturbances are located in northern Pakistan. The bulletin said that the intensity of rainfall caused by western disturbances over parts of northwest India will peak on Monday and decrease from Tuesday onwards. While there is unlikely to be a significant change in the extreme temperatures over northwest and central India over the next couple of days, they could rise by two to four degrees after that.

Forecasts indicate that the maximum temperature in Delhi is likely to remain below 40 degrees Celsius until May 26. Overcast skies and light rain expected for Tuesday as well, when the maximum temperature could stabilize at 34 degrees Celsius. While the maximum temperature is likely to reach 40 degrees again on May 27, it may rise further to 41 degrees Celsius on May 28 and 29.
