| Outline of Final Research Achievements |
By serving as cloud condensation nuclei, aerosols affect cloud microphysics, and as a consequence, they can affect cloud albedo, cloud amount, and precipitation. In this study we show using satellite-derived cloud data that cloud droplet number concentration increases over the East China sea where the Kuroshio ocean current with high sea surface temperature (SST) is located especially when cold air outbreak takes place. We also show using aircraft data that aerosol number concentration and vertical structure of cloud liquid water content are very different in precipitating clouds as compared with those in non-precipitating clouds. Using improved numerical models, we show that these observed features of influences of aerosols and SST on clouds and precipitation can be successfully reproduced.
