摘　　要：收集了～年间的国际气象船舶报资料,以中国台湾周边海区为中心,范围自 19601990 31 a 20°～°,°～°,划分为°×°网格单位,对风向、风速、浪向、浪高、周期等要素N28N116.5E124E11进行累年逐月统计和作图。通过分析研究,我们发现了该区的风浪特点和分布规律:冬季风浪以台湾海峡中部为最大,尤其是澎湖列岛北部地区(风速大于,浪高大于,但在台湾西南部沿岸以高 20 m/s 3.0 m )雄为中心,风浪最小;夏季风浪以台湾海峡南口为最大(风速大于,浪高大于,台湾海 13.0 m/s 2.0 m )峡风浪最小(风速小于,浪高小于。这些新的特点,在以往的°×°或°×°的大 1.0 m/s 1.5 m ) 22 55网格分析研究中是显示不出来的。The international meteorological data for shipping in the sea area of Taiwan from 20～°°～°—°×°28N and 116.5124E during 19601990 are analyzed taking 11latitude and longitude as statistical grids. The characteristics of the direction and velocity of wind, the height and direction of wave and the period of wave are stated by month and constructed. Through the study, we have found the laws governing the wind and wave in this area. That is, in winter the wind and wave are the highest in the middle of the Taiwan Straits, especially to the north of Penghu Islands, ( the velocity of wind is above 20 m/s and the height of wave is above 3.0 m ), while they are the lowest centring around Gaoxiong along the southwest coast. And in summer the wind and wave are the highest at the southern entrance of the Taiwan Straits, ( the velocity of wind is above 13.0 m/s and the height of wave is above 2.0 m), while they are the lowest in the Taiwan Straits, (the velocity of wind is under 1.0 m/s and the height of wave is under 1.5 m ). All these are °×°×°°submerged in the big grids of 22and 55latitude and longitude.
