一、前言冬季,袭击我国的强冷空气频繁南下,致使我国海区经常出现偏北大风,并拌有汹涌的海浪,严重地威胁着海上作业和航行的安全。本文利用国际、国内船舶报资料,分别针对四个海区形成巨浪时的天气形势(依其等压线的走向分为N、NE和NW三种类型),根据不同类型摘取两站间的气压差和海上相应的浪高或浪级资料,分别建立了各海区海浪的经验关系式。 I. INTRODUCTION In the winter, the strong cold air that hit our country frequently went south, causing northerly winds and frequent sea surges in our country’s sea areas. This posed a serious threat to the safety of offshore operations and navigation. According to the data of international and domestic vessels, the paper analyzes the weather conditions of the four sea areas (divided into N, NE and NW according to the trend of their isobars) The pressure difference and the corresponding wave height or wave data at sea, respectively established the empirical relationship between sea waves in each sea area.
