470大規模風場推定における気象衛星雲画像からの雲移動ベクトルの利用可能性の検討

Abstract

Now, the acid rain has become one of the environmental problems of global scales. In many cases, the cause substances of the acid rain are transported through a long distance. Therefore, the acid rain is not considered as domestic problems only. The long distance transportation model has been developed as one technique for solving the long distance transportation problems of the cause substances of such acidifying. In this model, presumption of a wind field is the most important factor.In order to apply this model to the East Asia area, we tried the presumption of the wind field using the cloud picture obtained from the GMS (Geostational Meteorological Satellite, Himawari by name.) We verified the accuracy of this wind field presumption technique by comparing mutually between the presumed technique of this wind field, the wind vector obtained by the Meteorological Agency Japan, upper-layers weather data, and the GPV (Grid Point Value) data.
