  We performed observational and numerical studies on the Venus atmospheric dynamics, and succeeded in finding topographic waves and thermal tides. We reproduced these waves in a general circulation model to elucidate their temporal and spatial structures and their effects on the general circulation and material transports in the Venus atmosphere. We found that streak features observed by an infrared camera onboard Akatsuki were generated by a front associated with baroclinic instability waves. We also obtained some results on the thermally stratified structures and the generation mechanism of the atmospheric superrotation.

  For gas absorption process, MstrnX was not simulated well in case of the quadruple CO2 condensation because it is assumed the doubling CO2 condensation in the previous version. In this study, we revise this model to correspond the quadruple CO2 condensation with the update of database. For particle scattering process, ice crystal habits was assumed sphere, so we modify it can be adopted the hexagonal column and aggregate particle. Moreover, large particle scattering are introduced, that is able to calculate the radiation effects of fog, rain, and snow particles that could not be calculated using the conventional method.
