Model WRF and its application for regional climate modelling in high resolution
Karlický, Jan ; Halenka, Tomáš (advisor) ; Belda, Michal (referee)
This work is dealing with regional climate models. Firstly, their principle and use of them is described, including advantages and disadvantages of this approach. Further, the application of WRF numerical weather prediction model in climate mode is described and differences in use of CLWRF modification and its advantages for getting results are discussed. Possibilities of this implementation and testing runs for finding appropriate settings are presented. Finally, the results of one ten-year and four five-year simulations of model with different settings are compared with observed values. Some chapters are dedicated to possibilities of processing and graphics outputs of model results and discussion.

Numerical weather prediction with WRF model
Kotků, Jirka ; Belda, Michal (advisor) ; Huszár, Peter (referee)
This bachelor's thesis deals with the comparison of the simulation results using different vertical coordinate systems, namely the terrain following system and the hybrid vertical coordinate system. We begin with the brief introduction of numerical prediction models in general and then the introduction of the WRF model used in this thesis. The attention is paid to the description of vertical coordinate systems as well as to the presentation of its components and the process of starting a simulation. The next section describes the setting of the WRF model used in this thesis. It is followed by the graphical output of the simulations with the comparison of the results. Comparison of the vertical temperature and wind speed profile was made with real data from the soundings performed in Prague-Libuš by the Czech Hydrometeorological Institute.

Turbulence modeling with WRF model
Peštová, Zuzana ; Belda, Michal (advisor) ; Halenka, Tomáš (referee)
This bachelor's thesis deals with the comparison of WRF simulation results using the Large Eddy Simulation (LES) and physical parametrization at lower resolution. The first part is dedicated to the turbulent flow and Navier-Stokes equations. This part also contains basic information on the methods by which we can model the turbulent flow. These methods are DNS, RANS and LES. In the next part, atmospheric numerical models are presented and the WRF model is described in more detail, including a description of its execution. The main part of the thesis deals with the description of the performed simulations and the comparison of the results. The results obtained are compared first with real data and then for individual simulations with different parameterizations. 1
