本研究利用2002年7月至2007年8月的美國NASA Aqua 衛星上所搭載的中解析度成像分光輻射計(Moderate Resolution Imaging Spectroradiometer, MODIS)之衛星葉綠素甲濃度與衛星海表面溫度資料與Quick Scatterometer (QuikSCAT)衛星的海表面風場資料,來研究西太平洋暖池區之葉綠素甲濃度、海表面溫度與海表面風場之長期月平均變化及跨年之季節變化關係。研究結果發現在研究區之北、東、南側之葉綠素甲濃度最高值出現在每年的第一季,而最低值約在第二、三季。在海表面溫度方面,暖池區由年初時向南移動,至三月始向北移動,到了十月又轉而向南移動。至於海表面風場方面,第一、二季時北區風場較強,風向多為東北風,第三、四季時南區風場較強,風向多為東南風,至於位於南北兩區之間的赤道地區則終年吹東風,但風速較前者為弱。除了年度性循環變化之外,聖嬰及反聖嬰現象也是重要的因素之一,當發生聖嬰現象時,在暖池區東側的葉綠素甲濃度會明顯下降,而海表面溫度卻是明顯上升,反聖嬰現象出現時,則葉綠素甲濃度明顯上升,海表面溫度則明顯下降。
The purpose of this study is to discuss the spatial and temporal variations of the chlorophyll-a concentration (Chl-a), sea surface temperature (SST) and sea surface wind (SSW) in the warm pool area of the Western Pacific Ocean by using the data of the Aqua satellite Moderate Resolution Imagining Spectroradiometer (MODIS and Quick Scatterometer (QuikSCAT) satellite SeaWinds during the period from February 2002 to August 2007. The result indicates that the Chl-a in the northern, eastern and southern regions of the study area appears to be the highest during the first quarter of the year, and lowest in second or third quarter. From SST observation, it is found that the warm pool area moves southward in the beginning of the year, then moves toward the North in March, and reverses direction again in October. From SSW observation, we can find that the SSW in the North region is always northeasterly and the strongest in the first and second quarter, while the SSW in the South region is southeasterly with the strongest in the third and fourth quarter. The SSW in the Equator region appears to be weaker and easterly all the year round. Beside the annual cycle of the Chl-a, SST, and SSW in the study area, the El Nino/ Southern Oscillation (ENSO) is also an important factor to influence them. When El Nino occurs, Chl-a in the east side of the study area decreases evidently with SST increasing, the reversing situation happen during the La Nina period.
