Recently the IMD (Indian Meteorological Department) has predicted that India will likely have a normal monsoon in 2020, with a chance of ‘above normal’ rain in August and September.
It has also officially redefined the definition of what constitutes ‘normal’ rainfall and reduced it by 1 cm to 88 cm from 89 cm.
The June-September rainfall accounts for 75% of the country’s annual rainfall.
The IMD issues a two-stage forecast: the first in April, followed by a more detailed one in the last week of May, which will also illustrate how the monsoon will spread over the country.
IMD relies on supercomputers, mathematically simulating the physics of the ocean and the atmosphere.
