Abstract :

In this study, the drag coefficient in Persian Gulf is computed by the Bulk Model and then the rate of evaporation and moisture flux has been computed in the Bushehr station for two dry and rainy years.   After some studies it has been realized that the amount of evaporation is more in summer than winter. The most evaporation has been hold in July.                 The rate of evaporation and moisture flux has been studied experimentally but it wasn’t successful. So it has been reviewed again because the experimental relation didn’t give the exact information. So the correct coefficient and new experimental relation obtained. The rate of evaporation and moisture flux has been calculated by the use of it, similar to the Bulk Model, the rate of evaporation is more in summer than winter .For more accurate study of the marine information, two months of a year (May and December) has been used as a sample. This study proved the results but there is a little difference between the evaporation in warm and cold months for high accuracy of the marine information. The evaporation has a direct relation with wind speed and temperature. It has been approved in the warm months. The wind speed and temperature is high but in cold months as the wind speed is high but temperature is lower than warm months for higher evaporation in warm months
