| Outline of Final Research Achievements |
This study investigated cumulous clouds and atmospheric turbidity in urban area using stereo camera images. Totally, 12 cameras were installed at 4 locations (3 directions of photos at 1 location) around Tokyo-Bay to monitor the visible atmospheric condition above the center of Tokyo. The major outcomes of research are as follows:
(1) Development of a cumulonimbus was monitored at two locations. Based on the stereo-image analysis, temporal evolution of the height of this cumulonimbus was quantitatively estimated from its initial stage to just before starting the heavily rain. (2) Summer in Tokyo near the coastal area, atmospheric boundary layer is often stratified to 2 or 3 layers judged from the direction of clouds movement. There is a considerable correlation between rainfall and the southern wind at the lowest layer. (3) Boundary layer height is estimated from the color in the sky. This results that the atmospheric boundary layer height develops about 1.5 km in summer.
