  1. 2012 /03 /14 Seasonal shedding of Loop Current eddies The fluctuations and the LC eddy shedding Yu-Lin Eda Chang

  2. 90LP 90LP de-monthly mean

  3. Corr (AVISO, SVD EC) 90LP 80-68w, 11-17n 0lag

  4. Corr 90LP dT/dy & AVISO SVD dT/dy 80-68w 11-17n dT/dy leads for 1~6 mo Monthly corr. is similar to 90LP but not better

  5. Corr 90LP Uw & AVISO SVD EC 80-68w 11-17n Uw leads for 1~6 mo

  6. Corr 360LP AVISO SVD EC 80-68w 11-17n

  7. 90LP

  8. Homogeneous correlation (SVDec, Original) 90LP

  9. Monthly result (no LP), clear biannual signal (E) (A) (B) (F) (C) 2. Pls. redo with “5-year moving” corrletation to get a nice and smooth curve. 3. Pls. replot left figure of this slide#9 (different new *.ps filename) of seasonal_20120314_eda_fluc_svd.pptx with the 3rd panel replaced by the monthly-ensemble plot (top panel of right figure of this slide). 4. Pls. replot left figure of this slide#9 (different new *.ps filename) of seasonal_20120314_eda_fluc_svd.pptx with 360d lowpasseddt/dy (thick red?) and 360d lowpassedUw superimposed also. (D) 1. Does a positive lag means dT/dy lead? To be consistent w/your older plot (MS fig.3), pls. reverse it to show positve when Uw leads. 5. Pls. repeat this extended-domain SVD (left figure of this slide#9) for 360d LP also. Repeat also using longer NCEP dataset so we can see the correlation wiith AMO – see #23 of seasonal_20120305_eda_fluc_svd-lyo.pptx.

  10. Monthly Corr [SVDec(dT/dy), Wind], no LP, Sep2Oct (top), Monthly (low)

  11. Monthly Corr [SVDec(-dT/dy), Wind], no LP, Sep2Oct (top), Monthly (low)

  12. Monthly Corr [SST, Wind], Sep2Oct (top), Monthly (low)

  13. 90LP 90LP de-monthly mean

  14. Corr 360LP AVISO SVD EC 98-65w 5-31n

  15. Eddy shedding time lag between EOF(1+2+3, summer & winter intrusion and shedding), EOF(1+2+3+4, BC included) and Original AVISO
