چکیده
The interaction between sea and atmosphere has profound effects on the regions climate. Meanwhile, the sea surface temperature is considered as one of the most effective components of water bodies, and the controller of many atmospheric behaviors. Because of the importance of sea surface temperatures effects on atmospheric elements and also given the role of global warming on land and sea surface temperature rise, in this study, using water temperature data from AHVRR sensor of NOAA weather satellite, the climatic data bank was prepared for 718 sites across the Caspian Sea for a period of 30 years. Then, the trend of sea surface temperature change was studied for four points in Caspian Sea. The results showed that the temperature has changed because of the short-term climate fluctuations type and has a trend that can be seen in some monthly and yearly series. It was concluded from studying the behavior of U and U' components changes related to the average temperatures of four points on an annual basis, a significant mutation with a positive trend was seen and confluence point of the two sequences from 1995 to 2000 is considered as the change point. In conclusion of studying the trend of Caspian SST, it can be said that some parts of this sea is going through the trend of temperature rise and partial warming, that it is consistent with the results of many studies in which the findings are consistent with warming and changes in sea surface temperatures of aqueous areas.
