  1. Eda 20100915 Tide Gauge & AVISO

  2. Mean SSH from Rio et al.2009 Black dots are the locations of the tide gauge stations. Blue contours are the isobaths. Time period of data Keelung: 1980-2009 Ishigaki: 1969-2008 Gangfeng: 1997-2007 Suao: 1999-2005 Lanyu:1992-2009 Dawu:2004-2009

  3. 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)

  4. EOF AVISO SSH: monthly

  5. EOF AVISO SSH: 360d running mean mode1: 67% mode2: 7.3% mode3: 3.9 %

  6. Mean wind stress (Pa) and curl (Pa/m) 1980~2008 Wind filed is dominated by winter monsoon

  7. EOF ECMWF wind stress curl: 720d running mean

  8. EOF ECMWF wind stress: 720d running mean
