Synoptice Analysis Impact Sea surface Temperature at Precipitaition in the province Mazandaran

In this research application Sea surface temperature, sea surface pressure and precipitation in the province Mazendaran was studied. Mean monthly sea surface temperature data in 30-year period has been from NOAA. 30-year average monthly precipitation data is taken from meteorological office for stations Babolsar, Qrakhyl, Noshahr and is Ramsrgrfth. The correlation between sea surface temperature with rainfall in different months in the province has been calculated. In each month and the third degree regression line was used for statistical estimation.In the present study is shown that there is the negative correlation whit 95 percent confidence interval between sea surface temperature Caspian Sea against precipitation and standardized precipitation index in the in Mazandaran province. Can be deduced., decreasing sea surface temperature in the years Precipitation will increase and rising Sea surface temperature Can be reduced rainfall.
