Determining the temperature of Caspian sea surface using the numerical, computational model

摘要

The time and relocation of the water surface play an important role in the activities of atmospheric system, marine life, sea flows, salinity and the other characteristics of seas or lakes. This research offers a numerical model for prognostication and determination of spatial and epochal distribution of the surface temperature of the southern part of Caspian Sea and the results were discussed in comparison with the observations. The above-mentioned numerical model is based on the equations dominantover the temperature and flow distribution and finite difference method has been used in order to solve the equations numerically and expand the equations. In this regard, the two-step Lakes-Wandrof semi sketches were used for advective items and Dofourt-Frankel patterns were used for distributive items. In this research which is used for environmental networking, the Arcaway "C" network is adjusted and is used in the earth spherical system with vertical sigma arrays. In order to solve the equations numerically, a computational program was provided and the used language was c++ and the output of this program is sketched by drawing programs such Surfer, Tecplot and Arcview. The results obtained from the numerical solution of the temperature equation have been compared with the information obtained from the field observations which indicate rather acceptable correspondence of the model with the observations.
