The Variability of Hydrographic Fields at Kuroshio's Turning on Northeast of Taiwan
臺灣東北角黑潮轉向處之水文場變化性
摘要
橫截臺灣東北角海域黑潮每月所量測的水文時間序列資料以經驗正交函數(EOF)方法分析，前三階即闡述了總變化量的50-70％，所揭示的物理過程有因太陽入射能量及黑潮主軸變動所引發的斜溫層及斜鹽層之季節性週期，有因黑潮地轉流的改變所影響的斜壓性，有因季風正交分量所帶動的中國東海水及太平洋海水間的成鋒過程，還有因洋流的地轉性而非一般所鹹信的大陸坡效應所衍生的湧升現象。

The empirical orthogonal functions analysis is applied to the time series of monthly hydrographic sections across Kuroshio near northeast of Taiwan. The EOF’s of the first three modes account for 50-70% of the total variabilities. Physical processes revealed are cycles of the seasonal thermocline and halodilne due to solar heating and shift of Kuroshio axis, the baroclinicity due to change of Kuroshio geostrophic velocity, the frontogenesis between East China Sea water and Pacific Ocean water due to orthogonal components of monsoon, and the upwelling induced by current geostrophy instead of the continental slope effect.
