    Winter
    (February 15) current velocity 
     | 
     | 
   
   
    vertically
    averaged within the mixed 
     | 
     | 
   
   
    layer.

    The
    observed flow field was produced 
     | 
   
   
    by
    initializing the model with Levitus 
     | 
     | 
   
   
    climatology,
    shutting off thermo- 
     | 
     | 
   
   
     | 
   
   
    dynamical
    forcing, and running the 
     | 
     | 
   
   
    model
    for two weeks. Substantial 
     | 
     | 
   
   
    transients
    remain in the equatorial 
     | 
     | 
   
   
    region. 
     | 
     | 
   
   
     | 
   
   
    The
    simulated fields are qualitatively 
     | 
     | 
   
   
    similar
    to each other and to the 
     | 
     | 
   
   
    observations.
    The surface flow in the 
     | 
     | 
   
   
     | 
   
   
    western
    subtropical gyre tends to be 
     | 
     | 
   
   
    more
    surface intensified in the two 
     | 
     | 
   
   
    HYCOM
    KPP simulations than in 
     | 
     | 
   
   
    other
    cases.
