We employ the methods of nonlinear time series analysis on a high resolution daily rainfall gridded data set from 1951 to 2007 for India to understand varying features and mechanisms of monsoonal precipitation over India. We present our result on novel emerging characteristics in the spatio-temporal behaviour of monsoonal precipitation in the warming atmosphere, showing a preference for certain type of rainfall events. We show that the complexity of individual rainfall events has changed over the last decades and how this change has manifested into droughts and rare rainfall events.
