The Impact of Air-Sea Interactions on Typhoon Structure

Abstract:

In this work, the results of a coupled experiment and an uncoupled experiment conducted in one of our former works are used to analyze the impact of air-sea interactions on the structure of typhoons. Results reveal that typhoon-induced SST decreases to reduce the latent heat fluxes transporting from the ocean to the atmosphere and cause the flux of sensible heat to transfer downward from the atmosphere to the ocean. Such SST reduction also has remarkable impacts on the typhoon structure by making the typhoon more axisymmetric, especially in the middle and high levels. This study also analyzes the basic characteristics of symmetric typhoon structure.
