Regression coefficient of rainfall and wind for the summer monsoon season. The regression coefficient (objective variable is precipitation) between interannual variation of rainfall and the wind field at 850 hPa (m s−1) (vector) for each cluster (a)–(e), and the distribution of the climatological values (averaged for 1958–2013) of seasonal precipitation and wind vectors at 850 hPa, as in Fig. 6b (f). Colored (red) vector shows significance over the 2% level based on the Student t-test
