| Abstract: | The distributed equation of the wind field with respect to height in Ekman layer has been deduced from the atmospheric horizontal motion equation. This equation is expressed by a 2-order linear differential equation. Numerical solution of 2-order linear differential equation with boundary condition is given by finite difference method. Computation simulation results are given in this paper. A brief analysis of the vertical distribution of the wind in Ekman layer can be found in the discussion. |
