Downscaling precipitation to river basin in India for IPCC SRES scenarios using support vector machine.

The article presents a discussion on the use of a Support Vector Machine (SVM) in downscaling precipitation to river basin in India. It describes a methodology which uses predictor variables from the National Center for Environmental Protection (NCEP) and from the third Canadian general circulation model (CGCM3) for special report of emission scenarios (SRES). The data includes thermodynamic parameters related with precipitation. NCEP and CGCM3 data were used to study seasonal stratification. Using the model the study found that precipitation is expected to increase in several emission scenarios. An overview of the study is provided.
