多地突发海水倒灌 是何原因？专家解读→

Core Viewpoint - Recent coastal flooding incidents in cities such as Panjin, Yingkou, Dalian, Jinzhou, and Huludao in Liaoning Province, as well as Tangshan in Hebei, were caused by a combination of tidal phenomena and weather conditions, specifically storm surges and their residual effects [1] Group 1: Causes of Coastal Flooding - The flooding was attributed to the natural tidal phenomenon, which is influenced by celestial bodies like the sun and moon, causing sea levels to rise and fall one to two times daily [1] - Weather conditions, including wind and atmospheric pressure changes, significantly impact sea level fluctuations, leading to storm surges that can elevate sea levels [1] - The phenomenon known as "storm surge residual" occurs when the effects of a strong weather event continue to influence sea levels even after the weather event has ended [1] Group 2: Expert Insights - According to Jiang Wensheng, Dean of the School of Environmental Science and Engineering at Ocean University of China, if weather-induced sea level rises coincide with high tide, it can result in exceptionally high water levels [1] - The recent flooding incidents were a result of storm surge residuals coinciding with high tide, leading to the observed coastal inundation [1]
