在冬季风盛行期间,于我国海岸附近常观测到一种波向与海上风向明显不同,由海向岸传播的涌,这种涌仅出现于离岸不远且水深较浅的沿岸一带,而其源地在天气图上并无反缺,故暂名之为近岸涌。过去,在波浪预报工作中,由于它没引起人们的注意,因此,往往造成漏报或“后报”错误。本文根据海上波浪和风场资料分析,说明这种近岸涌的存在及特点,并探讨其成因。 During the prevalence of the winter monsoon, it is often observed near the coast of our country a surge of waves of a different direction from that of the offshore wind that spreads from the sea to the shore. This surge occurs only in the coastal areas not far off the coast and at shallower depths and The source of the weather there is no shortage of maps, so tentatively named nearshore. In the past, in the wave forecasting work, because it did not attract the attention of people, it often resulted in underreporting or “post-reporting” mistakes. Based on the analysis of the wave and wind field data at sea, this paper shows the existence and characteristics of this nearshore inrush, and discusses its causes.
