摘　　要：本文利用唐山三岛海洋站2018-2020年的水文气象要素实测数据,对其气温、气压、降水、表层水温和盐度的年平均、月平均和年际变化进行统计分析,结果表明气温、气压、降水、表层水温和盐度具有明显的季节性变化特征。气温、表层水温夏季最高,冬季最低;气压与气温要素月均值曲线走势相反,夏季气压最低,冬季最高;降水主要集中在夏季;表层盐度春季、冬季高,夏季最低。Based on the measured data of Hydrometeorological elements of Tangshan Sandao ocean station from 2018 to 2020,this paper makes a statistical analysis on the annual,monthly and interannual changes of air temperature,air pressure,precipitation,surface seawater temperature and salinity.The results show that air temperature,air pressure,precipitation,surface water temperature and salinity have obvious seasonal variation characteristics.The temperature and surface water temperature are the highest in summer and the lowest in winter;The trend of the monthly mean curve of air pressure and temperature elements is opposite,the air pressure is the lowest in summer and the highest in winter;Precipitation is mainly concentrated in summer;The surface salinity is high in spring and winter,and the lowest in summer.
