詳細な雲の微物理過程を導入した二次元積雲の数値実験

Abstract

Cloud development was studied numerically in a deep, two-dimensional cloud model with detailed microphysics to examine role of ice. It was found that ice enhanced the precipitation particle production more greatly than when it precipitated in sole warm rain process. In addition, there are some indications thnt an ice phnse contributes greatly not only to precipitation but also to storm dynamics. In the model, a very long-lasting heavy rainfall was calculated in continental ice cloud.Wind shear effect on precipitation was also examined as a part of this study. As has been noted in many other papers, cloud with wind shear lasted much longer than in situations with no wind.
