Fig. 5: Potential driver and predictive signals of onset, withdrawal, and LRS of summer monsoon over NEI.
From: Present and future of the South Asian summer monsoon’s rainy season over Northeast India
The potential drivers from simultaneous correlations of detrended anomalous time series of a onset days, b withdrawal days and, c LRS days, with spatial detrended anomalous time series map of JJA (0) sea surface temperature (SST). The stippled regions indicate correlations significant at 95% level. And the potential predictive signals of LRS is checked through lead-lag correlation of its detrended time series with monthly box averaged SST (detrended) indices d interdecadal ENSO index (170°E, 280°E, 10°S, 10°N) minus (130°E, 200°E, 20°N, 50°N), e Atlantic Niño (320°E, 20°E, 10°S, 10°N), and f Niño3.4 (190°E, 240°E, 5°S, 5°N).
