本文根据1968～1981年台风期间的水位观测资料,对长涂岛的台风暴潮特性及影响因子作了统计研究。结果表明,1、长涂岛的台风暴潮主要发生在7～9月间,大于100cm的最大增水较少发生;2、台风过程最大增水与台风路径的关系密切,较大的台风暴潮发生在台风接近时;3、台风过程增水与岱山气象站(相距15km)的气压有较好的负相关。而与风速有较好的正相关;4、台风过程最大增水与天文潮高潮相遇并非罕见。
Based on the observation data of water level during the typhoon period from 1968 to 1981, this paper made a statistical study on the characteristics and influencing factors of typhoon surge over the island of Chang Tu Island. The results show that: 1. The typhoon surge in Chang Tu Island mainly occurs between July and September, and the maximum water gain greater than 100 cm occurs less frequently. 2. The maximum typhoon water increase is closely related to the typhoon path. The larger typhoon storm The tide occurred when the typhoon approached; 3. The typhoon process water had a better negative correlation with the pressure of the Daishan weather station (15 km apart). But with a good positive correlation with the wind speed; 4, the largest typhoon process of increasing water and astronomical tide encounter is not uncommon.
