An unexpected change in the weather condition due to an upper air cyclonic circulation over northern part of West Bengal and neighbourhood extending up to 0.9 Km above mean sea level’ left the capital city and surrounding areas with sudden fall of mercury by over 2 degree Celsius below expected temperature on Sunday evening.
The Meteorological Department in Ranchi has named it pre-monsoon phenomena, which is expected to cause thunder strike-backed moderate to heavy rain in some parts of State on Monday and onwards.
“This is all due to pre-monsoon phenomena that weather has taken such a turn. Though it is not unusual for us, as pre-monsoon activities start taking place from anytime in March to early April, the temperature is expected to remain on lower side with cold winds prevailing during evenings and nights for some days. This may also cause thunder strikes and moderate to heavy rains in some parts of the State,” said Met Centre Director in Ranchi BK Mandal on Sunday.
He added that such kind of sudden changes in weather behaviour was not so worrisome, as it was not there to last for long hours of the day. “Day hours are going to remain sunny and one can experience a sudden weather change in evening and night hours for mostly around a week. Moreover, moderate rain during second half of March is always welcomed by the farmers as many of their seasonal crops require some water in these days,” said Mandal. The department on Sunday evening has also lowered its temperature forecast for Monday from 29-17 degree Celsius (Upper-lower) to 27-16 degree Celsius for Ranchi and around.
At the same time, private weather forecasting agency Skymet has said that a trough is extending from Northeast India to Odisha across the West Bengal region. “Rains along with squally winds and hailstorm may occur over parts of West Bengal, Odisha and a few areas in Jharkhand along with South Bihar on Monday. In South Bihar and Jharkhand, rainfall activity will take a backseat on Monday onwards,” said Skymet.
