摘    要:利用常规观测资料、我国数值预报t213模式的实况资料和卫星反演资料,从天气学、能量学等方面对0906号西行台风和0908号转向台风进行分析,结果表明,中纬度环流平直,副高呈带状分布并加强西伸,同时大陆高压稳定维持的形势有利于台风西行;而副高东退并转为块状结构,大陆高压偏西的形势,则有利于台风向北转向;无论是西行还是向北转向台风的未来移动路径都将沿着最近前方的负散度中心或最大上升运动中心方向移动;另外,对流层底层以下大气高能区轴线方向对台风未来移动方向也有一定的指示意义.

关 键 词:典型台风  环流形势  内部特征  能量场  西行台风  转向台风

Abstract:This paper analyzes and compares the No.0906 and No.0908 typhoon from the synoptic meteorology,energy,etc.The research uses the conventional observation data and t213 data.The result indicated that mid-latitude circulation was flat,the subtropical was zonal distribution and strengthened to the westward extension simultaneously.Westward typhoon benefited from the stability of continental high-pressure.As well as,the subtropical zone went west and turned to the block.The west trend of continental high-pressure helped typhoon go north.However,the typhoon would turn to the center of the negative divergence of its nearest front(or the center of maximum upward motion).Additionally,the thesis also has the implications to the research about the future direction of movement of typhoon,which is in the axis of the high-energy zone under the lower stratosphere.
Keywords:typical typhoon  circulation situation  internal features  energy field  westward typhoon  turning typhoon
