Analysis of the Influence of Water Level Change in Guangxi Nearshore Caused by Typhoon Landed in the North of Beibu Gulf
摘要
Abstract
The influence of water level change in Guangxi nearshore caused by typhoon landed in the north of Beibu Gulf was analyzed according to the continuous current profile data measured at Station S1 in the south water of Bailong Peninsula,the tidal data measured at Station F1 during typhoon Nesat landed in Guangxi nearshore and the tidal data measured at Station F2 in Tieshan Port during typhoon Durian landing.The results showed that the maximum measured current speed and residual current speed of surface layer were 40 cm/s and 20 cm/s,respective﹣ly,at Station S1 during non-typhoon.But during the strong typhoon,the maximum current speed at the surface layer reached 103.7 cm/s,and the residual current speed was 39.7 cm/s, which was about 2 times during non-typhoon. With increasing water depth,the speed of tidal current and residual current were gradually re﹣duced.The water level at Stations F1 and F2 dropped to the minimum before typhoon land﹣ing,whereas the water level increased to the maximum after typhoon landing.Increasing or reducing of water level associated with the typhoon process.Meanwhile the change of water level rising or falling in Guangxi nearshore was closely related to the resonant interaction gen﹣erated by wind,harbor terrain and atmospheric gravity waves during typhoon landing.关键词
