Temperature is one of the fundamental parameters in physical oceanography and study of marine processes. The variation of Spatial and local of Sea Surface Temperature have an important role on climate change , life of fish, ocean currents, amount of salinity and the other carectistics of seas and lakes. The purpose of this research has predicted of sea surface temperature in the Caspian Sea. So the data on the Caspian Sea surface temperature (SST) that have been measured with Aqua satellite from MODIS sensor have been collected from 2003 to 2007 .This data analyzed by Fourier series method. Using Fourier analysis calculated Fourier coefficients and temperature predict for future year. Also average of sea surface temperature in three portion of Caspian Sea by 24 selected stations has been calculated. The pattern of sea surface temperature in different times of whole Caspian Sea during 2003-2007 was identified. The result of spectral time series is shown that temperature variation in different times have a same pattern. So in all stations spectral frequency have a 12 month periodic pattern.
