摘要
2014年登陆广东省湛江市徐闻县的台风"海鸥"与"威马逊"均先在海南文昌翁田镇登陆后并穿过琼州海峡,台风路径相似。"威马逊"是1973年以来登陆华南的最强台风,中心气压910 h Pa,最大风力17级(60 m/s),"海鸥"中心气压960 h Pa,附近最大风力则为13级(40 m/s)。从台风强度来说,应该是"威马逊"增水比"海鸥"要大,然而事实却是"海鸥"实际出现的风暴增水远比"威马逊"严重。为更好地理解风暴潮机理及现象,有必要深入地分析造成这种差异现象的原因。
In 2014, typhoon Kalmaegi and Rammasun made landfall over Xuwen County , Guangdong Province with the same path , both of which landed over Wengtian Town of Hainan Province and passed through Qiongzhou Strait in advance .Rammasun was the strongest typhoon landed in South China since 1973 with central pressure 910 hPa and maximum wind 17 (60 m/s), while Kalmaegi were 910 hPa and 13 ( 40 m/s ) comparatively .It seems that the storm surge of Rammasun should be stronger than Kalmaegi , actually it is the other way around .To better understanding this phenomenon , the reasons and mechanism were discuss in this assay .
