Description 671-686
A three dimensional hydrodynamic model (COHERENS) has been used to study monthly circulation and water mass properties of the Caspian Sea. Boundary conditions given to the model were river discharge, wind speed, air temperature, relative humidity, cloud cover and precipitation rate. Model simulation showed cyclonic circulation in December and January especially in the south and middle of the Caspian Sea. Moreover, wind velocity and temperature had an important role in the formation and variations of currents in the Caspian Sea. The thermocline that was established in the southern coast of the Caspian Sea according to field data and results of model simulation, showed relatively similar trends, such that the thermocline is created at the depth of 30 to 40 meters in the Anzali port region during autumn and then the thermocline vanishes in winter with the decrease in temperature. In spring the thermocline layer is recreated at a depth of about 10 to 20 meters.
