Previous studies indicated a relationship between deep convection and sea surface wind patterns; however, it remains difficult to remotely observe a deep Convective System (CS) and its dynamics above the ocean due to the lack of data at the mid atmospheric levels. To collect the details of the CS dynamics, some nearly simultaneous data of three CS features, that is, cloud brightness temperature, vertical wind at the midlevels, and horizontal wind at the sea surface, can be now obtained by a combination of sensors from a geostationary (Meteosat) and two polar‐orbiting satellites (Sentinel‐1 and Aeolus), having corresponding acquisition time and orbit track matching. This work thus illustrates a nearly three‐dimensional view of the CS atmospheric dynamics over the sea, including deep convective clouds observed by Meteosat, intense downdrafts measured by Aeolus, and strong surface winds estimated by Sentinel‐1.
