Various PUMP figures

Various PUMP figures collected

  1. Work with the GFDL and NCAR IPCC runs.

    All plots are direct comparisons between the two models.
    1. Profiles at the equator:  
      1. On z:   u (compare TAO)   v (compare TAO)   w   u and w

    8. GP1-01 (Jan 01):      u     v     dv/dy     w      w100m

    9. Estimating a y-scale:
      1. v:  (1) Overlay all v sections
             (2) Meridional correlation functions
             (3) Only overall mean   Vertical structure
      2. u: (1) Overlay all sections (20m)    100m
             (2) Meridional correlation functions
             (3) Vertical structure   0-50m and 100-150m

             (4) U and V overlaid   c

      3. w at 100m:  Original spacing    Smoothed (about 75km)
           Meridional correlation functions

  4. Upward extrapolation of TAO ADCP velocities
    Use the newly functional Sontek point ADCPs to check the upward vertical extrapolation of 300m ADCP velocities:
    1. Compare ADCP and Sontek velocities at specific depths: u   v
    2. Check extrapolated gradients against true 10m velocities: u   v
  5. G/C model upwelling:
    1. Mean model upwelling
    2. Annual cycle upwelling

    2. Ekman divergence by longitude
    3. Geostrophic divergence by longitude
  7. Climatologies at 140°W, 125°W, 110°W:
    1. 140°W
    2. 110°W
    3. All 3 (T only)
  8. Overlays of SST at 140°W (a la Fig 1 of document):
