Abstract We examined atmospheric responses to 35,000+ oceanic eddies in the Kuroshio Extension region during period of 2006–2009. Using satellite data, we showed that cold (warm) cause surface winds decelerate (accelerate) and reduce (increase) latent sensible heat fluxes, cloud liquid water, water vapor content, rain rate; all these changes are quantified. Both linear correlation between wind divergence downwind sea temperature (SST) gradient correspondence vorticity crosswind SST support vertical momentum mixing mechanism, which indicates perturbations modify by changing turbulent marine boundary layer (MABL). High‐resolution National Centers for Environmental Prediction Climate Forecast System Reanalysis (CFSR) data can reproduce MABL albeit with some differences intensity. In addition, CFSR reveal not confined MABL. deepens (shoals) over warm (cold) eddies; enhanced (reduced) transport transient zonal occurs from about 850 hPa level; velocity anomalies penetrate beyond into free atmosphere; there exists a positive correlated relationship convective rate anomalies, indicative ocean eddies' impact on troposphere. However, composites different results based data.
