夏季副热带中—中间尺度系统发展的一种机制

A Mechanism of Development of Meso - Medium Scale System over the Subtropical Belt in Summer

本文研究了夏季副热带中—中间尺度天气系统的发展问题,结果表明,在潮湿不稳定大气中,扰动与凝结释热之间的正反馈过程是系统初期发展的一种机制,非线性作用将抑制系统的无限发展,使之发展到一定强度后即处于稳定状态。

In this paper, the development of meso - medium scale systems over the subtropical belt in summer is studied. Results show that: in a wet unstable atmosphere, the positive feedback between disturbance and condensation latent heat is the mechanism resulting in the development of this system. Nonlinear actions suppress the unlimited development of the systems.
