影响热带气旋结构和运动的两类因子的数值研究

NUMERICAL STUDY ON THE IMPACT OF TWO KINDS OF FACTORS ON TROPICAL CYCLONE’S STRUCTURE AND MOTION OF TYPHOONS

中文关键词:  热带气旋  结构  移动  β效应  涡度平流

英文关键词:Tropical cyclone  Structure  Motion  Beta effect  Vorticity advection

中文摘要:

      利用一个β平面正压准地转模式,实施了4组时间积分大于5d的试验.结果表明:涡度平流和β效应同样重要,它们对热带气旋的结构和移动均具有明显影响.

英文摘要:

      By using a beta-plane quasigeostrophic barotropic model, four numerical expertments whose integration times are larger than five model days are performed.Results show that the vorticity advection term and beta term are two basic factors impacting on the structure and motion of typhoons.
