一、绪言海上大风与渔业生产、海上运输,部队作战以及海上空间作业等都有很大影响。作者大致概括了日本当前定量预报海上大风的现状,介绍了实用的适于业务上计算的风预报方法,同时对实测风和计算风速之间的关系进行了天气学和统计学讨论。风的定量预报,首先要预报气压梯度及其变化,但现在的气压形势预报,要使精度和时间间隔都十分满意还不行。即使气压形势的预报很准,风随地区和时间的变化仍很大。因
I. INTRODUCTION The gale at sea has great influence on fishery production, maritime transportation, combat operations of troops and operations in the sea space. The author generalizes the present situation of Japan’s current quantitative forecast of wind gust at sea, introduces a practical wind forecast method suitable for business calculation, and conducts a synoptic and statistical discussion on the relationship between measured wind and calculated wind speed. The quantitative forecast of the wind, we must first forecast the pressure gradient and its changes, but the current pressure situation forecast, to make the accuracy and time interval are not satisfied with the full. Even if the prediction of the atmospheric pressure situation is accurate, the change of the wind with the region and time is still very large. because
