前言海雾是低层大气水汽凝结的产物。海雾的分布、多少及其变化对海上交通运输、海上施工以及舰艇训练都有一定影响,如果能提前几个月、半年甚至更长的时间知道某海区、某个岛屿海雾日的多少,便可对有关物资、人员及其舰船进行更合理的调配。因此国内一些部门尤其是海军早已把海雾长期预报提到日程上来。但是目前从事海雾预报及研究工作者注意短 Foreword Sea fog is the product of low-level atmospheric condensation. The distribution of the sea fog, how much and its changes have an impact on maritime transport, offshore construction and naval training. If we can know the sea fog days of a sea area and an island months or months ahead of time, It will be possible to allocate the relevant materials, personnel and their vessels more rationally. Therefore, some domestic departments, especially the Navy, have long put the long-term forecast of sea fog on the agenda. However, currently engaged in sea fog forecasting and research workers pay attention to short
