| Research Abstract |
In order to investigate features of small and medium scale disturbances in the Martian atmosphere, which would play important roles to lift dust, numerical simulations of Martian atmosphere with quite high resolutions are performed. The horizontal grid sizes of simulations ranges from about 90 to 11 km. Simulation results show many kinds of atmospheric disturbances with various horizontal scales. Further, the results show that such small scale disturbances contribute dust lifting significantly. These results imply that the understanding of features of such disturbances is necessary to consider maintenance mechanisms of current Martian climate.
