Plain Language Summary: This study investigated the influence of sea surface temperature (SST) on the September 2015 Kanto-Tohoku heavy rainfall event using a regional air-sea strongly coupled data assimilation system. The air-sea coupled system improved the analysis of SST, air-sea latent heat fluxes, lower-atmospheric components and the stationary linear convective system including local torrential rain occurred around 37°N in the Tochigi prefecture.
