Bhubaneswar, Jul 21:
The El Nino effect on the south-west monsoon has resulted in Odisha receiving five percent less rainfall till July 20, the Indian Meteorological Department (IMD) has said.
“As against the average monsoon rainfall of 426 mm by July 20, the state has received 405 mm rainfall so far this year, an IMD release said.
“Generally 5-6 low pressures are formed in the Bay of Bengal in July. However, there has been no low pressure in the Bay of Bengal this year. The only low pressure formed was on the land on July 9. Since the cloud mass created by low pressure in the Bay of Bengal usually results in normal rainfall in the coastal region, there has been less than normal rainfall this year due to absence of ocean based low pressure under the influence of El Nino in the Pacific Ocean,” said Dr Sarat Chandra Sahu, director, Regional Meteorological Centre, Bhubaneswar, today.
As per official reports, there has been less than average rainfall in Odisha in July. While Boudh has recorded 40.1 percent less rainfall, Gajapati has 37.4 followed by Jagatsinghpur (30.1), Kandhamal (49), Keonjhar (41.5), Khordha (34.9), Koraput (63.6), Malkangiri (60.5), Nabarangpur (42.7), Nayagarh (39.5), Puri (43.7), Rayagada (32.1) and Sonepur (29.7).
Sahu said though there is an indication of a low pressure along the Odisha coast in the last week of July.
“Though there would be average rainfall in the state with comparatively more rainfall in the north and interior Odisha till July 23, the rainfall will increase from July 24 onwards, Initially, there would be heavy rainfall in the north and interior Odisha which will subsequently extend to the coastal region up to the south,” he added.
