KOLKATA: Twin thunderstorms hit Kolkata on Friday whilst a cloud-mass unfold over a 30km radius and 10km in peak engulfed town sky since overdue morning. The storms, which had a moderate wind pace between 25km/hr and 30km/hr, brought the mercury down by means of almost five°C and Kolkata gained eight.3mm rain throughout the day.
While the first thunderstorm struck shortly after 10am, the second one lashed town around five within the night time. The morning storm used to be led to by means of clouds that shaped within the neighbouring districts and in Bangladesh. The night time one, however, originated across several south Bengal districts and used to be a classical nor’wester, mentioned the Regional Meteorological Centre (RMC).
It used to be the thickness of the afternoon cloud-mass that cut out sunlight almost utterly, leaving town dark. It pressured streetlights to be switched on and bogged down site visitors motion.
“It used to be the thickness of the cloud and the fact that it hardly moved for hours that resulted within the darkness. The cloud hung low over town for greater than 3 hours. Small clouds that had originated in East Burdwan, East Midnapore, North and South 24 Parganas, Hooghly and Howrah merged to shape a large and thick mass that covered Kolkata,” mentioned RMC director G Okay Das.
He added that such localized cloud masses were not unusual within the weeks preceding the coming of monsoon. “Pre Monsoon cloud formations are smaller and extra localized. Since the heating gets reduced within the Jharkhand space – where nor’westers originate – clouds creating within the areas closer to town converge to trigger thunderstorms,” explained Das.
The morning thunderstorm, too, used to be a result of localized clouds and those which had shaped in neighbouring Bangladesh. While it had little impact at the temperature, the afternoon cloud quilt pulled the mercury down by means of about five°C. The temperature dropped to 27°C around 2pm. According to a private climate forecasting service, mercury dropped to 26°C within the night time and the RealFeel temperature used to be 32°C. Friday’s thunderstorms took the tally for the month to 5. The city has gained 3 squalls this month.
Even even though the temperature dropped, the thundershower failed to have an impact at the humidity. The city recorded a maximum relative humidity of 92% while the minimum used to be a steep 72%. A steady incursion of moisture from the sea used to be accountable for the prerequisites. “This assists in keeping the chances of further thunderstorms alive,” mentioned Das.
