| 摘要: |
| 珠江是我国三条最大的河流之一，由三大支流——东江、北江和西江组成。珠江口是三角洲网河区型的河口,无数水道彼此交织,方向各异。大小不一,地形十分复杂。每当台风侵袭本区时,强制波夹带盛潮进入河口向内推移,与洪水相遇时,则相互拥高,水位暴涨,严重威胁着珠江三角洲地区人民的生命财产。
统计表明(见图1),1949-1970年间,侵袭广东沿岸地区的台风共有149次;平均每年7次，八、九月份出现最多,约占58%，五月和十一月份最少,占8%。可以认为,珠江河口区是我国风暴潮的多发区。
近几年来,关于珠江河口区台风暴潮的研究和预报已有论述,获得了一些有益的成果。本文仅对珠江口(伶仃洋)台风暴潮的一些特性从理论和实相结合的角度予以讨论。 |

| Abstract: |
| The general characteristics of typhoon surges at the mouth of the Zhujiang River (Pearl River ) are analyzed in this paper.The fundamental mechanisms of storn surge such as 1) the change of storm surge in relation to the typhoon track and wind; 2) the relations between surges and velocity of the river flows; 3) the seiche and wave are also discussed according to theoretical model. |
