| 摘 要： | 针对台风登陆预报业务及防台减灾工作中的“登陆”和近年来广为使用的“擦边”等的模糊表征问题，本文从登陆和擦边的基本词义出发，结合台风特殊的水平结构，分析了台风在近岸区域移动时台风与海岸线间的相对位置特征，给出了“登陆”和“擦边”的具体判别办法，以避免实际业务中可能出现的用词用语的混乱现象。

| Abstract: | Based on the basic meaning of these words related to the typhoon movement and the special horizontal structure of typhoon, we focused on the ambiguous statements of landfall, touch and graze typhoon, and analyzed the location relationship between coastline and the position of typhoon when it moves along or close to the coastline, thus obtained a specific method to identify the landfall and touch typhoon, so as to avoid the possible confusion of wording in operational forecasting. |
