Venusian sulfuric acid cloud deck exists in the altitude of 50km-70km. It is considered that this cloud affects atmospheric general circulation by reflecting and absorbing solar radiation and emitting heat. It is known that this cloud varies temporaly and spatially. I study the production/extinction system and distributions of  sulfuric acid clouds on general circulation of Venus’ atmosphere using Venus General Circulation Model (VGCM). Presently, I try to reproduce variations of sulfric acid vapor, and I want to reproduce radiation from sulfuric acid cloud and reveal the effect eventually.
