We provide three tests analytically and numerically in terms of the 3- dimensional simulation model of local wind. These tests are to examine a) two differential methods for linear terms. b) four differential methods and two time marching methods for the advection term and c) five turbulent models for the vertical transportation in the basic equations of atmosphere motion. From these testa we conclude that a) the 4th order central difference method can be the most suitable for calculating linear terms, b) the Matsuno scheme, which is a kind of implicit method, and the 4th order central differential method can be the most suitable for calculating the advection term and c) the level 2.5 model combined with the transfer equation of the q<SUP>2</SUP>l can be the most suitable for the meso γA scale problem under consideration.
