This type of variation in rainfall can be useful to many researchers, agricultural scientists, program managers and even tourists visiting the state.
An analysis of the active monsoon conditions of the past week recorded at the city’s rain gauge station by meteorologist and retired National Institute of Oceanography (NIO) scientist MR Ramesh Kumar revealed this pattern in the maximum amount of rainfall, its timing and trend.
Kumar told TOI, “Most of the rainfall occurred from midnight to 12 am to 8.30 am. Barring a few exceptions, rainfall was minimal from 8.30 am to 2.30 pm. Also from 2.30 pm to 12 midnight, an increase in rainfall was observed in most cases.”
The occurrence of night time maximum rainfall over the coastal region can be attributed to the feedback of solar influence on the formation of rainfall over the coastal regions, he added.
“Much can be done using the available database of India Meteorological Department (IMD)imd), like the present study of diurnal variation of rainfall,” Kumar said.
Goa has been witnessing an increase in Monsoon activity since last week. The IMD has explained the reason; A monsoon trough at mean sea level, a cyclonic circulation over the middle Madhya Pradesh And a cyclonic circulation lies over South Odisha & neighborhood. A low pressure area is also likely to form over west-central and adjoining northwest Bay of Bengal.
All rain gauge stations have been closed as a result of increased rainfall activity. Goa – Leaving Mormugao and Dabolim Crossing the 2,000 mm mark in seasonal total rainfall.
