Abstract
Estimation and observation of SST by NOAA/AVHRR were carried out in the Ariake-kai bay and the Shimabara bay that are located in the west of Kyushu island to understand the heat movement. Local coefficients of estimation equation (MCSST) for SST in the Ariake-kai bay were calculated. The Fourier analysis of SST from NOAA/AVHRR was done to obtain the spatial distribution of annual variation of SST. Results show meteorological and geographical effects on heat environment of shallow and closed bay. A calculation of heat exchange using heat balance model gave us the results. which express the interesting movement of heat.
