outline • EOF (AVISO SSH, ECMWF wind stress, curl) • Mean wind stress and curl • Correlation Coef. , regression and time series of: North Taiwan (tide gauge & AVISO) South Taiwan East Luzon • AVISO SSHA Latitude-Time plot (eddy propagation)
EOF AVISO SSH: 360d running mean mode1: 67% mode2: 7.3% mode3: 3.9 %
Mean wind stress (Pa) and curl (Pa/m) 1980~2008 Wind filed is dominated by winter monsoon
