Delhi temperature drops by more than 5°C after brief rain, more showers predicted on weekend
According to MeT department, more such showers that would hit the national capital over the weekend would keep the day temperatures well below 40°C.delhi Updated: Jun 01, 2017 11:04 IST
A short shower that lasted for less than five minutes on Friday afternoon helped the mercury level dip from around 38.6°C to around 33°C — a drop of more than five degrees in less than an hour.
The city received just around 0.2 mm of rain. According to officials from the MeT department, it was the cool moist winds which accompanied the rain that helped the temperature to drop drastically.
Met officials said that more such showers are expected to hit the national capital region over the weekend, which in turn would help to keep the day temperatures well below 40°C.
“One or two spells of thunderstorms or dust storms accompanied by squally winds reaching 55 kmph or more could hit a few places across Delhi and NCR over the weekend,” said a senior official of the Regional Weather Forecasting Centre.
MeT officials explained that a western disturbance is approaching the Indian boarder from Afghanistan, as a result of which moisture-laden winds are gushing into the mainland.
As it approaches, the western disturbance is helping another wind system — a circulation — to form over Punjab and Haryana. “With winds from the Arabian sea bringing in loads of moisture, these two systems together would help churn out rain in the northwestern states. This is a typical phenomenon which we usually get during this time of the year,” said the official.
And it won’t just be Delhi-NCR alone to get relief from the rising mercury. MeT officials expect almost all states in north-west India including Jammu and Kashmir, Himachal Pradesh, Uttarakhand, Punjab, Haryana, Delhi, Uttar Pradesh and Rajasthan to receive rain.
The hilly regions of Jammu and Kashmir, Himachal Pradesh and Uttarakhand would receive fairly widespread rain, while Delhi, along with others states in the plains, would receive scattered and isolated rain.
“But rain or no rain, the thunderstorm and squally winds would be enough to arrest the rising mercury level at least for a brief period. We expect the day temperature to come down to around 38°C over the weekend. This would plummet further once rain lashes the city,” said the official.
The thunderstorm would cool down the air in the high altitudes and because of the convection current, this colder air mass would come down to lower levels.
The mercury had shot up to more than 42°C earlier this month resulting in heat waves.
