Analysis of coupled ocean‐atmosphere numerical simulations revealed a widespread oscillation of Sea Surface Temperature (SST) and surface wind anomalies with a cyclic nature characterized by a period of three to six days. Similar oscillations were also found in buoy data at different locations around the globe and in an atmospheric reanalysis, albeit the oscillations were noisier and stronger in the observations and they were weaker and longer‐period in the atmospheric reanalysis. These oscillations did not, however, develop in an atmosphere‐only simulation, suggesting the importance of ocean‐atmosphere coupling for simulating this phenomenon. We propose a mechanism for this interaction involving a feedback between SST and surface wind.
