摘要
利用海岛站和陆地站的实测水文气象数据,初步分析了海水表层温度和气温的变化特征,同时分析了不同天气系统影响下两站点海水表层温度的变化规律。结果表明:两站点水温和气温月变化趋势一致,二者相关性较好,水温变化略滞后于气温且水温变化幅度较气温偏小;水温和气温的月均日变化呈现相同趋势,具有明显的日变化周期;冷空气影响下,气温下降开始时间呈现先北后南的规律,但水温下降时间陆地站早于海岛站;台风影响下,陆地站水温变化相对平缓,而海岛站水温波动明显。
Using measured hydrometeorological data from island and land stations,this study preliminarily analyzes the variation characteristics of sea surface temperature(SST)and air temperature,and examines the changes in SST at the two stations under the influence of different weather systems.The results show that the monthly variation trends of SST and air temperature at both stations are consistent,with a good correlation between the two.The change in SST lags slightly behind that of air temperature,and the amplitude of SST changes is smaller than that of air temperature.Both the monthly average and daily variations of SST and air temperature exhibit similar trends and show a clear daily variation cycle.Under the influence of cold air,the start time of air temperature drop follows a pattern from north to south,but the SST decreases earlier at the land station than at the island station.Under the influence of typhoons,SST changes at the land station are relatively stable,while at the island station,SST fluctuations are more pronounced.
