一、前 言 国内不少海洋学者对西北太平洋及我国近海波浪场进行了分析研究,并获得了许多成果[1][2],但至今还没有人对北大西洋波浪场进行分析研究,国外这方面的论述也较少。近年来随着远洋航行、远洋捕捞和援外港工建设的发展,研究探讨世界其他各大洋的海洋环境已成为急待解决的问题之一。本文用1980年11月至1982年11月二年的天气图、波浪资料,将气旋波浪场分为强、中、弱三种类型进行探讨,结果表明:强气旋波浪场是造成北大西洋海难事故的主要天气系统,而北美冷高和极地高压是形成强气旋的主要因素,从而北美冷高和极地高压的变化则是预报这种灾害性天气和造成恶劣海况的最重要的指标。
I. INTRODUCTION Many oceanographers in China have carried out an analysis and research on the northwestern Pacific Ocean and the offshore wave field in China and have obtained many achievements [1] [2]. But so far no one has done any research on the North Atlantic wave field. The discussion is less. In recent years, with the development of ocean-going navigation, offshore fishing and the construction of foreign aid to Hong Kong, studying and studying the marine environment in other oceans of the world has become an urgent issue to be solved. This paper uses the weather charts and wave data from November 1980 to November 1982 to divide the cyclone wave field into three types: strong, medium and weak. The results show that the strong cyclone wave field is caused by the North Atlantic shipwreck Of the major weather systems, while cold and polar high in North America are the major contributors to strong cyclones. Changes in the cold and polar high in North America are therefore the most important indicators of this catastrophic weather and adverse sea conditions.
