【摘要】 采用NCEP/NCAR全球对流层1°×1°再分析格点资料和实况观测资料,选取2001～2008年导致青岛暴雨的6个登陆台风个例,从路径、结构、强度等方面对其特征进行分析。结果表明:台风沿西北-北-东北路径移向中高纬时,会给青岛带来暴雨天气,台风东移入海,再次登陆山东半岛且登陆点离青岛越近,暴雨越强、范围越广;台风影响青岛时,已处于生命史中的衰亡阶段,低层暖心结构已经破坏,但中高层暖心结构仍较明显,强度仍会维持一段时间;台风低压与高空冷空气结合导致青岛的暴雨天气更为强烈。更多还原

【Abstract】 The NCEP/NCAR globally tropospheric 1°×1°reanalysis and obveratary data have been employed to select six landfall typhoon cases in order to diagnose characters of typhoon by path,structure and intensity etal.Results show that heavy rain will occur in qingdao when typhoon goes toward mid-high latitude by the path of northwest-north-northeast,and when typhoon goes east to sea,the smaller the distance between landfall point and qingdao;Typhoon has been weaken and the structure of warm-center in low level has gone away when it affects qingdao,but the structure of warm-center in mid-high level is still clear and the intensity will go on for a time;The heavy rain in qingdao will be more strong when cold air in high level goes into the typhoon low.更多还原
