Local Air?Sea Interactions at Ocean Mesoscale and Submesoscale in a Western Boundary Current

We present results from a new, global, high-resolution (?3-km for ocean and ?6-km atmosphere) realistic earth system simulation. This simulation allows us to examine aspects of small-scale air-sea interaction beyond what previous studies have reported. Our study focuses on recurring intermittent wind events in the Gulf Stream region. These induce local heat fluxes above Sea Surface Temperature (SST) anomalies with horizontal scales smaller than 500-km. In particular, strong latent bursts warm SST are observed during these events. show that such associated secondary circulation acts fuel by transferring dry air momentum down surface. The intensity this is related strength fronts border anomalies. phenomena requires both atmospheric oceanic components model.
