Abstract

Cyclones with characteristics similar to tropical cyclones, although smaller in size,are sometimes observed in the Mediterranean Sea. Several studies have analyzedtheir genesis, evolution, and decay, shedding some light on the mechanismsresponsible for their development. However, some of these cyclones were notproperly reproduced in terms of track and intensity by neither real-time simulationsnor hindcasts, emphasizing the delicate role of small-scale upper level features inthe development of these cyclones.Also, the cyclone intensity is very sensitive to the intense fluxes between the oceanand atmosphere in the high-wind core. The importance to reproduce properly theair-sea interaction has been recently investigated by means of a coupledatmosphere-wave-ocean model (COAWST), which exchanges consistently the seasurface fluxes between the atmospheric model (WRF) and the ocean circulationmodel (ROMS), including also the effect of waves (SWAN).Finally, considering the importance of sea spray droplets in the air-sea exchange,an integrated numerical study has been undertaken, using the wave model SWANtwo-way coupled with WRF-CHEM (the WRF model integrated with the chemistrypackage). A new sea spray generation function under severe wind condition isproposed in WRF-CHEM, in particular in the GOCART aerosol module, whichexplicitly considers the emission and transport of sea spray aerosol.
