Areas containing water reservoirs or lakes have big impact on the weather formation. It is known that inland water bodies, such as lakes and reservoirs, represent a special type of underlying surface when interacting with the atmosphere. In this work, various approaches to modeling the state of the atmosphere and, in particular, the wind speed over the territory containing an inland reservoir are applied within WRF atmosphere model. The calculations are performed for three (cell spatial resolution of 1.11 km), four (cell spatial resolution of 370.37 m) and five nested domains (cell size of the fifth domain is 111 m) for different types of underlying surface. The use of specialized parameterization of the gray zone is considered. The possibility of using LES at different spatial resolutions, with a different number of nested domains is studied and its advantage is shown. Field measurements data is used to verify the results.
