    Winter
    (February 15) S along 
     | 
     | 
   
   
    33W
    to a depth of 500m. The thick 
     | 
     | 
   
   
    line
    is the mixed layer base. 
     | 
     | 
   
   
     | 
   
   
    The
    simulated fields are generally 
     | 
     | 
   
   
    similar
    in structure and are 
     | 
     | 
   
   
    reasonably
    consistent with the 
     | 
     | 
   
   
     | 
   
   
    observations.
    A major exception is 
     | 
     | 
   
   
    the
    lower nearsurface S in the interior 
     | 
   
   
    subtropical
    gyre for the HYCOM 
     | 
     | 
   
   
    K-T
    MICOM mode simulation. This 
     | 
     | 
   
   
     | 
   
   
    is
    associated with the westward 
     | 
     | 
   
   
    displacement
    of the region of large 
     | 
     | 
   
   
    salinity
    in the subtropical gyre 
     | 
     | 
   
   
    relative
    to the location in other 
     | 
     | 
   
   
     | 
   
   
    HYCOM
    simulations and in 
     | 
     | 
   
   
    observations
    that was documented 
     | 
     | 
   
   
    in earlier
    slides.
