台风环境场特征相似预报方法

The Typhoon Forecasting System Build on Similar Characters of Synoptic Situation

摘要: 通过多种场相似计算方法的试验比较,提出环境场特征的场相似分析方法,建立台风相似预报系统。利用1950—2006年NCEP再分析资料,计算关键区域的物理量场特征值;设计图形识别程序,获取每个台风过程的天气形势场各种特征值;建立环境场

Abstract: Based on studying several similar methods,the environmental character fields similar analysis method is given and typhoon forecasting system is build on it.With the NCEP/NCAR reanalysis data from 1950 to 2008,the
