The effects of Atmospheric parameters on the sea level fluctuation in the east coasts of Caspian Sea(Mazandaran province)

Investigating of Caspian sea water fluctuation as the biggest lake in the world is necessary for all its neighbours.In this research,a comprehensive study has been done effects of atomosphric parameters in the sea level fluctuation from the East coasts of Mazandaran province.After studying the validity, altimetry field data were averaged monthly, and barometric pressure, Evaporation effect and precipitation effect on sea level have been investigated using meteorological data.The above steps have been done using satellite data as well. The result of this research has shown that sea surface temperature and The result of this research has shown that sea surface temperature and air temperature have an increase trend in the east coast of south Caspian sea. A high correlation is shown between air temperature and mean sea level.(0.51 in Nowshar and 0.77 in Neka) and the increases of sea surface temperature have inverse effect and increases of air temperature have direct effect on the sea level change.so the effect of air pressure on the sea level change is higher than the evaporation and precipitaion has been recognized. The effects of the independent variable and their correlations have been studied, using step by step regression method.The best model was selected for sea level variations from three independent variables(climat).
