In the table above the figures in the bracket with the year is the SW Monsoon rainfall of those respective years. Here we can see that even though the highest rainfall in these six years was in 2020 at 956.7 mm, the highest number of Very High and Extremely Rainfall and their total have all been the highest for 2024 when the SW Monsoon rainfall at 934.8 mm was lower than that in 2020. This is possibly an indication of increasing intensification of rainfall pattern with changing climate.
The figures of Very High and Extremely High Rainfall frequency in SW Monsoon are several times higher than those of 100-200 mm and 200+ mm rainfall in our district wise rainfall figures since the former figures are station wise whereas the latter are the average of all stations in any district.
