摘要
根据天气系统的定义和实际业务中的天气图分析规范,总结出了500、700、850hPa3层高空天气图上特征等高线、特征等温线、槽线(含切变线)、高(低)中心、冷(暖)中心以及热带气旋的识别方法及其判别式,并给出了实现计算机自动识别的程序设计步骤。
Based on synoptic systems' definations and meteorogram analysing standard, methods and formulas, to distinguish typical equiscalar line, trouth-line, high center, low center, cold center, warm center and tropical cyclone are summed up,and the distinguishing procedure with computer is given.
