摘　　要：热带洋面上的中小尺度天气系统能够产生强烈的大风、阵雨和大浪天气,他们的形成、发展和移向对航行船舶有很大的影响.本文针对船舶在中小尺度天气系统影响下,对其环境条件、结构和不稳定性进行动力诊断分析和理论研究,它在云图上和雷达回波上产生典型暴雨、雷暴、对流云、中尺度物理量场等带状分布,提出客观的、人为的安全性指标,重点解决对航行安全影响大的问题.The meso-and micro-scale systems in tropical sea can produce strong winds, showers and waves, whose formation,development and shift have a great impact on the vessels underway. This paper,aiming at the ships in the meso-and micro-scale systems, carries out a dynamic diagnosis analysis and theoretical research on the environmental conditions, structures and instability. It generates zonal distributions such as typical storms, thunderstorms, convective clouds, mesoscale physical quantity fields on the cloud chart and radar echo and puts forward objective, artificial safety indicators to solve the major problems affecting navigation safety.
