| Outline of Final Research Achievements |
Following results on cloud characteristics were obtained through data from active and passive satellite sensors together with numerical meteorological model outpus. To investigate the effect of water temperature change in the East China Sea on the cloud internal structure, clouds over the Kuroshio current (hereafter, On-Kuroshio) and around the Kuroshio current (hereafter, Off-Kuroshio) were compared. Then precipitating clouds were geometrically thicker for On-Kuroshio remarkably. Moreover, rain intensity inside clouds increased from the bottom to middle parts for On-Kuroshio. On the other hand, On-Kuroshio clouds had a heating rate of 2-4K/day in the bottom to middle parts. This values is somewhat low compared to sensible/latent heats, but it was suggested that the heating rate was an important factor to change the temperature.
