  2. Outline • Part 1: MAB • Part 2: GOM

  3. Part 1: MAB • Period: 1993 to 1999

  4. Mean V at bottom level • K=kb-1, kb-2 • Monthly • Whole

  5. month #2 Kb-1 Kb-2

  6. month #5 Kb-1 Kb-2

  7. month #8 Kb-1 Kb-2

  8. month #11 Kb-1 Kb-2

  9. whole Kb-1 Kb-2

  10. Mean SSH and V(k=13) • K=13 is about sigma=0.5 (mid level)

  11. month #2 SSH T(k=13)

  12. month #5 SSH T(k=13)

  13. month #8 SSH T(k=13)

  14. month #11 SSH T(k=13)

  15. whole SSH T(k=13)

  16. T at -50m and -500m • interpolation

  17. month #2 T(-50m) T(-500m)

  18. month #5 T(-50m) T(-500m)

  19. month #8 T(-50m) T(-500m)

  20. month #11 T(-50m) T(-500m)

  21. whole T(-50m) T(-500m)

  22. Section Volume transport (U) from shelf to isobaths • 60m • 100m • 200m

  23. Fine Grid Domain

  24. 1993 to 1999

  25. winter summer spring autumn

  26. Volume transport at sections (Savidge) AN A B C

  27. Part 2: GOM assimilation using Kathy’s SSHa observations • 6 cases: (1 day assimilation time interval) • Case A: Assimssh • Case B: Assimssh + Kathy’s obs (immediately) • Case C: Assimssh + Kathy’s obs (0.5 day later) • Case D: AssimEnoi • Case E: AssimEnoi + Kathy’s obs (immediately) • Case F: AssimEnoi + Kathy’s obs (0.5 day later)

  28. Domain and obs time coverage • 2003-4-9 to 2004-3-26

  29. Case B Spatial CC Temporal CC

  30. Compare Satellite and Kathy’s obs • Exclude data point where spatial CC < 0.7

  31. Case B Before exclude After exclude

  32. Case A Before exclude After exclude

  33. Case C Before exclude After exclude

  34. Case D Before exclude After exclude

  35. Case E Before exclude After exclude

  36. Case F Before exclude After exclude

  37. Part 2 conclusions • Difference between satellite and Kathy’s observation does affect assimilation significantly. • Difference lasts longer, results are much worse. • The region of low temporal CC is related to the difference between satellite and Kathy’s observation.
