Monsoon season has finally come to an end after three months of torrential rains. With the last day of September, the rainfall figures have come to a conclusion. The data and figures are now out there.
And to everyone’s dismay, an unusual trend has been observed in the Monsoon performance this year. The Monsoon season has ended with a countrywide excess rain of 10%. This ‘excess’ rainfall has happened after a gap of 25 years. The last excess rainfall was seen in 1994.
Monsoon performance can be mainly categorized into five namely ‘Drought’, ‘Below Normal’, ‘Normal’, ‘Above Normal’ and ‘Excess’.
Monsoon is expected to remain somewhere close to ‘Normal’ ‘Above’ or ‘Below Normal’ categories. Statistical records suggest that extremes are rather rare.
However, looking back at the data for the last 70 years from 1950 to 2019, we see that Monsoon has not always performed in the Normal range. The Monsoon performance for the last 50 years differs from ‘Normal’ category.
In the last 20 years, from 2000 we have seen Monsoon end ‘Below Normal’ or in a ‘Drought’ category. Whereas in the last 50 years, excess rainfall category years have been more. Moreover, the 50s have been the rainiest years in history with more than 10% rains. The list comprises of the years 1953, 1955, 1956, 1958 and 1959. It will not be wrong to call the last 50 years the rainiest on an average. Also, 1961 has been the only year with above excess rain of 22%.
