After a delay of a week, monsoon hit the Kerala coast on Saturday, marking the official commencement of the four-month rainfall season in the country.
“Monsoon has made an onset over Kerala today (June 8),” said India Meteorological Department’s Director General-designate Mrutyunjay Mohapatra.
Several parts of Kerala have started receiving a good amount of rainfall.
The news will augur well for the country as large parts have been witnessing agriculture distress and water levels in reservoirs in west and south India have dipped to low levels.
Most of rural India depends on the four-month monsoon season, which accounts for 75 per cent of the annual rainfall, due to a lack of adequate alternative source of irrigation. A good monsoon has a direct impact on the economy as agriculture remains the major contributor to India’s GDP.
The north Indian plains, central India and parts of south India have been recording temperatures over 45 degrees Celsius. Mercury has soared to over 50 degrees in parts of Rajasthan.
On Thursday, IMD said the arrival of monsoon in Delhi is likely to be delayed by two-three days from its usual onset on June 29. However, Skymet said it may take at least a week longer.
The city is likely to receive normal monsoon. Northwest India, too, is likely to have normal monsoon.
The IMD declares the onset of monsoon over Kerala if after May 10, sixty per cent of the available 14 stations Minicoy, Amini, Thiruvananthapuram, Punalur, Kollam, Allapuzha, Kottayam, Kochi, Thrissur, Kozhikode, Thalassery, Kannur, Kudulu and Mangalore report rainfall of 2.5 millimetres or more for two consecutive days.
This is one of the important parameters to declare the onset of monsoon. The other two factors are speed of the westerlies and long-wave radiation.
In 2016, the monsoon arrived on the same day.
