A cyclonic circulation over North Bay of Bengal has led to moist winds converging over Bangladesh, West Bengal and Jharkhand due to which good amounts of rain are being observed in the region. The system however, has decreased the rainfall activity over Northeast India by sucking away all the moisture from the area.
Due to the cyclonic circulation, fairly widespread rain over Gangetic West Bengal and Jharkhand in the last few days has pushed up the rainfall figures in the region. For instance, rainfall in Jharkhand was 7% deficient by the end of June. But till July 19 it has recorded a surplus of 13%. Similarly, Gangetic West Bengal was deficient by 4% but good rainfall activity has made the region surplus. From June 1 to July 19, rainfall in Gangetic West Bengal is excess by 23%.
According to rainfall data available with Skymet Meteorology Division in India, Bankura in West Bengal has received 69 mm of rain in a span of 24 hours from 8:30 am on Sunday. The state capital Kolkata has witnessed 40 mm of rain. While Jamshedpur and Ranchi in Jharkhand have recorded 14 mm of rain each.
The cyclonic circulation which is giving rain in the region has now moved inland and is stationed over Jharkhand and adjoining Gangetic West Bengal. Due to the system, both the sub-divisions will continue receiving moderate to heavy rain for next 48 hours. This spell of rain is expected to push the rainfall amounts in the region even further.
Daltonganj in Jharkhand has received exceptionally heavy rain from the period July 16 to July 17. According to the data available with Skymet, the city has altogether recorded a whopping 490 mm of rain.
