Abstract
Waves critically modulate the air-sea fluxes, and upper-ocean thermodynamics in a Tropical Cyclone (TC) system. This study improves the modeling of TC intensification by incorporating non-breaking wave-induced turbulence and sea spray from breaking waves into an atmosphere-ocean-wave coupled model. Notably, wind forecast error decreased by around 10% prior to TCs' peak intensity. The positive feedback of sea spray along with compensatory negative feedback from non-breaking waves, overall enhanced TCs' intensity. These breaking and non-breaking wave-coupled processes consistently cool sea surface temperature, resulting in improvement of the modeled SST. Observed improvements in full-year TC c..
