| 摘 要： | 采用福建沿海4个站点(包括浮标)2016年的实测水文气象数据,初步分析了不同天气系统影响情况下海表温度的变化特征。研究结果表明:福建沿海月均海温日变化和气温日变化有一定关系,二者都有明显的日变化周期,海温的日变化的峰值略滞后于气温日变化的峰值;无明显天气系统影响时,海温和气温的变化趋势比较一致,有冷空气或台风系统影响时海温和气温的变化趋势不再一致;冷空气系统影响时气温下降的时间从北到南依次滞后,而海温的下降从北到南延迟不明显;7月上升流的作用使得古雷浮标附近海表温度降低,并且周期发生明显改变。

| Abstract: | This study preliminarily analyzes observed hydro-meteorological data of four sites(including buoys)along Fujian coastal waters in 2016 to reveal the variation characteristics of sea surface temperature(SST)under the influence of different weather systems.The results show evident diurnal cycle of both monthly-averaged SST and air temperature,in which the peak of SST lags that of air temperature.The variation trends of SST and air temperature exhibits distinct consistence without influence of significant weather system.However,the consistence vanishes with influence of cold air or typhoon.Air temperature starts to decrease from the north to the south under the influence of cold air system,whereas the decrease of SST doesn't show evident lag between the north and south.The SST near Gulei buoy decreases attributed to the upwelling in July with significant variation of its cycle. |
