No 'Excess' Monsoon In 21st Century So Far, Seasonal Rainfall Lowers Consistently
Seasonal rainfall during southwest monsoon mostly hangs around 'Below Normal', 'Normal' and 'Above Normal'. The other 2 categories of 'Drought' and 'Excess' get outnumbered by large margins. 'Drought' or Deficient' monsoon is announced when the seasonal rainfall drops below 90% of long period average (LPA). Similarly, 'Excess' monsoon is declared when the rainfall climbs to > 110% of LPA.
