海风发展对模式初始场依赖的敏感性试验

本文建立了一个二维的中尺度静力模式，考虑了长短波辐射，湿凝结和土壤等物理因子，用六种典型的初始风场对海风发展作了敏感性试验，发现至少有一部分中尺度系统发生发展的结构与性质可以不依赖于初始场的中尺度特征，而是由局地中尺度强迫作用决定的。但是，中尺度系统的强度与位置仍然受初始场的影响。

NUMERICAL SENSITIVITY EXPERIMENTS OF SEABREEZE DEVELOPMENT DEPENDING ON THE INITIAL WIND FIELDS

A two dimensional static model is develoed in the present paper, taking into account the physical processes such as the longwave and shortwave radiations, wet condensation and the soil layers. The six canonical initial fields are used to investigate the sensitivity effect on the seabreeze. The constructure and characteristics of some mesocale systems, except the strength and position, are not dependent on the initial mesocale characteristics, they are determined by local forces.
