Climate Network Based Index Discovery for Prediction of Indian Monsoon

Identification of climatic indices are vital in essence of their ability to characterize different climatic events. We focus on discovery of climatic indices important for Indian summer monsoon from climatic parameters surface pressure and zonal wind velocity. We use climatic network based community detection approach for discovery of climatic indices. New indices depict better correlation with monsoon than existing indices. Regression and non-linear models are designed using newly discovered climatic indices for prediction of Indian summer monsoon. Models show superior accuracy to existing state of art models.
