The relationship between tropical cyclone frequence and air circulation, polar ice, SST and some kinds of circulation index is analyzed by using NCAR/NCEP reanalysis dataset including 500 hPa geopotential height, SST, and polar ice.

• 采用NCEP/NCAR再分析的500hPa高度场、海温场(SST)、极冰资料,分析讨论了登陆广东省热带气旋活动异常与大气环流、极冰、SST、各种环流指数等影响因子之间的关系,得到登陆广东省热带气旋(TC)偏多、偏少年对应的大气环流、极冰、SST、各种环流指数的概念模型。
