Abstract :
Interaction between sea and air is an important factor in controlling seasonal climatological variations in each environment. In this research, relationship between Sea Surface Temperature (SST) and wind speed over coastal area of Hormozgan province has been studied. Initially the SST data of the area were collected using AVHRR sensor of NOAA satellite and the wind speed data were collected from QuikSCAT satellite. After analyzing the satellite data for the SST and wind speed, monthly, seasonal and annual variations of these data were studied. The significance of their variations were evaluated during years 1985-2008, using a long term study group of each variable as a control and then comparison was made using Duncan test. As the increasing trend of mean annual surface temperature and the decreasing trend in wind speed was significant, correlation coefficient between SST and wind speed was obtained. After plotting the time against surface temperature during the study period, it was observed that the minimum temperature was 21.11 ˚C in 2008 and the maximum was 33.12 ˚C in 2002. It was shown that there was 4.2 ˚C temperature difference between western and eastern region of the sea coast in summer and the temperature gradient reaches 3 ˚C in winter. It can be concluded that for summer 75% and for winter 33% increase (decrease) of the mean sea surface temperature takes place and the deviation of mean wind speed will be increase (decrease).
