Fig. 9: Schematic summary of the anomalies following cross-equatorial DI events that reach the Arabian Sea.
From: Enhancement of Indian summer monsoon rainfall by cross-equatorial dry intrusions
Progress and position, horizontally and vertically, of the dry intrusions are shown in a. Line contours present the horizontal progress of DIs relative to the initiation time of descent, i.e., 0 (green), 48 (orange), and 120 (cyan) hours respectively. The shaded trajectory represents the vertical position along a schematic example of a DI event for 120 h. The mean anomalies of ocean evaporation (orange arrows), wind speed at 850 hPa (red arrows), and precipitation (blue drops over India) during the days following DIs are shown in (b). The horizontal blue line marks the equator.
