摘要
对１９８７～１９９２年在汕头以北登陆的全部台风个例分析表明：登陆台风陆上活动类型和远距离暴雨特，点与台风在近海的活动方式有关；登陆台风远距离暴雨的发生与台风登陆前后大气低层东南气流里是否存在中尺度暖区有关，落区与中尺度暖区在台风、副高系统中的相对位置有关，最后，建立了台风远距离暴雨预报的天气学模式。
Case study is made of 1987～1992 typhoons landing north of Shantou,South China,indicating thati)categories of the onland activity and rainstorms far away from the storms bearrelation to modes of activity offshore and ii) such rainfall depends on the presence of a mesoscalewarm sector in the low-level southeasterly around the landing,with the fallout band associatedwith the relative position of the warm sector to the typhcon′s and the subtropical high′s centerswhereupon a synoptical model is constructed for distant typhoon-rainstorm。
