Land Surface Schemes (LSMs) are among the most important components used in climate predictions, numerical weather prediction and hydrology. Their most important task is the solution of energy and water budget in land surface. MM5 model is the fifth- generation NCAR / Penn State mesoscale model used in studying of air pollution, numerical weather prediction and hydrology. This model contains of land surface parameterization schemes, radiation, convection, boundary layer and rainfall schemes, which are connected directly to each other. The Land surface parameterization scheme in this mesoscale model contains of Bucket, Force-Restore, five- layer soil, OSU and PX schemes. In this paper, according to the importance of the land surface schemes, it has been tried to study the physics details of these land surface schemes used in mesoscale model of MM5 in detail.
