摘　　要：根据1950～1995年共46a的北印度洋气象船舶资料,按5°×5°网格统计单元,绘制了历年各月风向频率、平均风速、6级和8级大风、能见度(≥10km和≤4km)、雾和雷暴等气象要素分布图。较为详细地分析了北印度洋风、能见度、雾、雷暴、热带气旋等海洋气象要素的分布特点及其年变化规律。该区是世界著名的季风气候区,夏季的西南季风比冬季东北季风强盛,与我国南海海区的季风特点正好相反。The meteorological data for shipping in the North Indian Ocean during 1950-1995 are analyzed taking 5°×5° latitude and longitude as statistical girds. Meteorology elements distribution charts such as wind direction frequency, average wind speed, strong breeze, gale and visibility (≥10km and ≤4km), frog and thunderstorm etc are drawn for every month. This area is the world-famous monsoon area. The southwest monsoon in summer is stronger than the northeast monsoon in winter. In this article, the authors analyze and describe in details the characteristics and changing laws of the wind, visibility, fog, thunderstorm in the North Indian ocean.
