摘要:
|
| 采用福建沿海4個(gè)站點(diǎn)(包括浮標(biāo))2016年的實(shí)測(cè)水文氣象數(shù)據(jù),初步分析了不同天氣系統(tǒng)影響情況下海表溫度的變化特征。研究結(jié)果表明:福建沿海月均海溫日變化和氣溫日變化有一定關(guān)系,二者都有明顯的日變化周期,海溫的日變化的峰值略滯后于氣溫日變化的峰值;無明顯天氣系統(tǒng)影響時(shí),海溫和氣溫的變化趨勢(shì)比較一致,有冷空氣或臺(tái)風(fēng)系統(tǒng)影響時(shí)海溫和氣溫的變化趨勢(shì)不再一致;冷空氣系統(tǒng)影響時(shí)氣溫下降的時(shí)間從北到南依次滯后,而海溫的下降從北到南延遲不明顯;7月上升流的作用使得古雷浮標(biāo)附近海表溫度降低,并且周期發(fā)生明顯改變。 |
| 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. |
