     the atmosphere and the underlying ocean are closely coupled. the ocean plays an important role in establishing and changing the earth’s climate. both the ocean and the atmosphere transport energy and exchange it with each other and their dynamics are coupled through exchange processes at their common interface. the main goal of this paper is to investigate the air-sea interactions on interannual and decadal time scale in the persian gulf. 34 years of data (1967-200) are used to investigate air-sea interaction in the persian gulf. an empirical orthogonal function (eof) and singular value decomposition (svd) analysis are applied to determine the coupled modes of variability of monthly sea surface temperature (sst) and sea level pressure (slp). we find that the the four leading eof patterns of sst are found. these modes together account for 99.8% of the total monthly sst variance. individually they explain 90, 9%, 7, 5%, 1% and 0, 4% of the variance. according to the north el al. (1982), the difference between the forth and fifth eigenvalue is comparable to the magnitude of the sampling errors, which means that the error in the eofs is comparable to the size of the eofs themselves. the temporal variability of each eof, obtained by the expansion coefficient of spatial patterns .
