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 hPa,最大风力17级(60 m/s),“海鸥”中心气压960 hPa,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。
2014年登陸廣東省湛江市徐聞縣的檯風“海鷗”與“威馬遜”均先在海南文昌翁田鎮登陸後併穿過瓊州海峽,檯風路徑相似。“威馬遜”是1973年以來登陸華南的最彊檯風,中心氣壓910 hPa,最大風力17級(60 m/s),“海鷗”中心氣壓960 hPa,附近最大風力則為13級(40 m/s)。從檯風彊度來說,應該是“威馬遜”增水比“海鷗”要大,然而事實卻是“海鷗”實際齣現的風暴增水遠比“威馬遜”嚴重。為更好地理解風暴潮機理及現象,有必要深入地分析造成這種差異現象的原因。
2014년등륙광동성담강시서문현적태풍“해구”여“위마손”균선재해남문창옹전진등륙후병천과경주해협,태풍로경상사。“위마손”시1973년이래등륙화남적최강태풍,중심기압910 hPa,최대풍력17급(60 m/s),“해구”중심기압960 hPa,부근최대풍력칙위13급(40 m/s)。종태풍강도래설,응해시“위마손”증수비“해구”요대,연이사실각시“해구”실제출현적풍폭증수원비“위마손”엄중。위경호지리해풍폭조궤리급현상,유필요심입지분석조성저충차이현상적원인。
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 .
