The paper describes the objective classification procedure of climates of the atmospheric boundary layer and climatic regionalization performed using the area of Western Siberia as an example. Four homogeneous areas were revealed for winter period and four areas were revealed for summer period. For each area the local statistical models were constructed. These models include the model profiles of altitude distribution of mean values, root-mean-square deviations, and matrices of interlevel correlation of temperature, mass part of vapor, zonal and meridian wind.
