增强显示红外卫星云图在热带气旋分析中的应用

THE APPLICATION OF ENHANCED INFRARED IMAGERY TO THE TROPICAL CYCLONE ANALYSIS

摘要: 本文给出了用增强显示红外卫星云图确定热带气旋中心位置的方法.通过对1983年我国编号台风定位的检验,表明这个方法可用于台风预报业务.文中还对VernonF.Dvorak估计热带气旋强度方法作了简化和改进,给出了热带气旋强度T指数与风速和气压的对应关系,同时还举例说明了如何应用这个方法及其效果.

Abstract: This paper proposes a method of locating tropical cyclone center with enhanced infrared imagery.This method was tested against the 312 locations of the 21 typhoons in 1983 has been proved usable in operation.The paper also simplifies and improves the method of Vernon F.Dvorak,for estemating tropical cyclone intensity.
