A recent regional finer grained climate model from researchers at Purdue University confirms what global climate models have been telling us for some time. That monsoon patterns will change both in the timing of the advent of rains and in the amount of precipitation. The map below shows the across-country expected changes in both these parameters. The basic lessons from these studies are that: 1) the country will get hotter 2) rainfall pattern will be more unpredictable 3) rains will be concentrated in shorter more intense bursts 4) periods of drought will last longer 5) overall, regions which experience less rainfall can expect even less rainfall, those that experience a lot of rain can expect little change or an increase in rain.
