Anomaly of wind speed at 850 hPa (m s−1, black contours), ocean evaporation (W m−2, orange contours), and moisture transport (integrated from the surface to 200 hPa, kg m−1 s−1, shading) at a the start of a DI event, ts, b end of a DI event, te, c 1 day after te, and d 5 days after te. Cyan contours represent a 0.01% occurrence frequency contour of Arabian Sea DIs during the corresponding stage in its lifetime. Dashed and solid contours represent negative and positive anomalies, respectively. All the anomaly fields shown are statistically significant (P > 0.05). The black box in d marks the area in the central Indian Ocean (CIO) with maximum ocean evaporation following te.
