Observed changes in extreme wet and dry spells during the South Asian summer monsoon season
@article{Singh2014ObservedCI, title={Observed changes in extreme wet and dry spells during the South Asian summer monsoon season}, author={Deepti Singh and Michael Tsiang and Bala Rajaratnam and Noah S. Diffenbaugh}, journal={Nature Climate Change}, year={2014}, volume={4}, pages={456-461} }
The South Asian summer monsoon has an impact on over one billion people. This study applies statistical techniques to precipitation observations (over the period 1951–2011) and finds significant increases in daily precipitation variability, the frequency of dry spells and the intensity of wet spells, whereas dry spell intensity decreases.
