The tantrums of the maverick weather continued on Monday, with minimum temperatures rising in most parts of the state and the maximum readings taking a dip.
Weathermen attributed the freak streak to clouds and moisture incursion into the atmosphere in the wake of a weak low-pressure trough over the Gangetic Bengal.
They said a western disturbance hovering over northern India was also affecting climate in Jharkhand. But, the effect would be short-lived. A brief and moderate cold phase is expected to make a comeback after 72 hours, they added.
Night readings on Monday rose by three degrees in Jamshedpur and its adjoining areas. The local weather observatory recorded 10.4°C against 7.4°C a day before. The temperature was three notches below the average normal.
The maximum, on the other hand, took a tumble because of morning haze and clouds. The city recorded 23.1°C against 25.3°C a day ago.
Capital Ranchi’s minimum of 7.6°C on Monday was also higher than 6.4°C some 24 hours ago. The day reading plummeted to 21.5°C from 23°C.
The minimum in Koderma, Hazaribagh, Simdega, Dhanbad and Santhal Pargana districts increased by a few degrees too. Cloudy conditions dragged down the maximum in all such places.
In contrast, Bokaro saw a drop in its minimum reading — from 10.2°C to 6.7°C. Weather officials blamed it on a local high-pressure gradient.
A.K. Sen, the director of Patna Meteorological Office, said there would be no significant changes in maximum and minimum readings in the next two days. “But, the mercury will see a rising trend.”
Sen ruled out the possibility of rain, but hinted at dipping night readings after 72 hours. “Incursion of moisture into the atmosphere has resulted in clouds. Foggy conditions also prevail at higher altitudes. It is an indication of change of season,” he explained.
A weather analyst at the Regional Meteorological Centre in Calcutta said winter was likely to wave goodbye in the third week of February.
