Cyclonic circulation leads to widespread rain in Jamshedpur


Jamshedpur, March 18: A cyclonic circulation with a low pressure trough resulted in thunderstorms and rain across the city.

An east-west trough  from cyclonic circulation over southwest Rajasthan and adjoining Kutch to Bangladesh across Madhya Pradesh, north Chhattisgarh, Jharkhand and Gangetic West Bengal at 1.5 Km above the mean sea level, led to change in weather conditions.

” Thunderstorm with gusty winds reaching a maximum speed of 40 Kmph are very likely at  isolated places especially in central and north eastern parts of the state during the next two days, ” said a senior official at the Ranchi Met Centre.

The weatherman said that apart from the cyclonic circulation, a trough running from north Madhya Pradesh across northern parts of West Bengal extending upto 0.9 Km above the mean sea level is impacting Jharkhand’s weather. The cyclonic circulation was extending 1.5 Km above the mean sea level.

Meanwhile, winds moving at a speed of around 30 Kmph swept across various parts of the state this evening including Kolhan region, Simdega, Gumla, Ramgarh and Khunti. The Met department had issued an alert of thunderstorm in all such places three hours in advance.  

A duty officer at the Ranchi Met office said that cells of thunder clouds ( usually referred to as convective clouds) formed over Chhotanagpur plateau region due to heavy moisture incursion into the atmosphere. He said an abundance of moisture caused by the combination of  the two  weather systems, especially the cyclonic circulation, led to formation of convective clouds.  

Around 5 pm today, it had become so dark in Jamshedpur and its neighbouring places that cars had to switch on their head lamps. The day temperature hovered around 35 degree Celsius in Kolhan region, three notches below normal. Light rain was also reported from a few isolated pockets.
