Figure 6. Spatial structure and northward propagation of MISO. Lead-lag regression of TRMM precipitation (shaded) with respect to a reference time series of rainfall anomaly averaged over central India (average over 72oE to 82oE and 18oN to 28oN). Regression averaged over 70oE–90oE as a function of lead-lag and latitude in the bottom right panel indicates the evolution and northward propagation of the MISO.
