摘　　要：利用秦皇岛、兴城以及葫芦岛3个测站的气象及潮位的连续观测资料,对2007年3月东北及华北部分地区56 a来同期最强的暴风雪强天气过程引起的辽东湾西部特大减水事件进行了分析研究。结果表明,本次天气过程引发的秦皇岛、兴城及葫芦岛三站的最大减水分别达到了-217 cm,-228 cm及-230 cm,接近或超过了百年一遇减水强度,这为辽东湾西部海域的工程分析及风暴潮研究提供了实测参数。范围大、持续时间长、风力较强的离岸风的作用是造成本次辽东湾西岸强减水的主要原因。The low water event in the western Liaodong Bay in March 2007 is analyzed, which is caused by the strongest snowstorm in the recent 56 years in the northeast China and the north China. The data used in this study are the meteorological and tidal data observed at Qinhuang-dao, Xingcheng and Huludao stations. The results show that the lowest water levels respectively observed during the storm at Qinhuangdao, Xingcheng and Huludao tidal gauge stations are 217 era, 228cm and 230 era, being equivevlent to or above the values in the 100 years return low water level caused by storm. This study provides observation parameters for marine engineering design and storm surge research in the western Liaodong Bay. Analyses also indicate that the low water event is mainly caused by the large-scale continuous strong offshore wind in this area.
