| Description |
In the backdrop of a changing climate, we investigate whether the Indian summer monsoon is changing either in
terms of duration or spatial coverage. Such an analysis specifically for the continental Indian region has both
conceptual and societal implications, and has been lacking. We show here, based on an analysis of daily gridded
observed rainfall data for the period 1951–2003, that there are decreasing trends in both early and late monsoon
rainfall and number of rainy days, implying a shorter monsoon over India. Similarly, there is a sharp decrease in the
area that receives a certain amount of rainfall and number of rainy days during the season. These trends are
consistent with other variables like OLR and rainfall from independent data sets; in particular, the land-ocean
temperature contrast has a decreasing trend, consistent with a weakening monsoon. The results emphasize need for
careful regional analysis in drawing conclusions regarding agro-ecological sustainability in a changing climate.
