Comparison of the Mean Wind Speed Fields Computed by Three Models over the Area of the Czech Republic

Three different mathematical models were used to calculate the local average wind speed over the complex terrain of the Czech republic. The models are based on different methodology: a statistical model with 3D interpolation, a microscale model with interpolation, and a dynamical model. The models were supplied with meteorological, terrain and roughness digital data. The results were compared and obtained differences are displayed in the attached figures. Over most of the country the results were very close. Greater differences revealed areas not suitable for use of a particular model, which was, besides the assessment itself, also the main purpose of the project.
