三维中-β尺度模式研究：一次气旋暖区锋生活动的中尺度结构的数值模拟试验

A STUDY OF MESO-βSCALE MODEL:THE EXPERIMENTAL SIMULATION OF THE MESO-SCALE STRUCTURES GENERATING IN FRONTOGENESIS

摘要: 设计了一个中-β尺度数值模式,并用来试验模拟一次京津地区暖区锋生降水过程。其结果不仅给出了暖锋式锋面垂直环流(热力直接环流),而且还给出了叠加在其上的次级中尺度环流结构。这说明该模式具有研究中-β特征运动的能力。

Abstract: A meso-β cale model hasbeen designed through which a simulation test has been done for a frontogenesis.The frontal vertical circulation(thermal direct circulation)has been demostrated and on which several subscale cells have suPerimposed.These characteristic motions are of meso-scale.
