    KPP
    Procedure (part 1): 
     | 
     | 
   
   
     | 
   
   
     | 
    – | 
    Apply
    surface thermodynamical and momentum flux forcing 
     | 
     | 
   
   
     | 
   
   
     | 
    – | 
    Calculate
    K profiles for interior diapycnal mixing from surface to bottom 
     | 
   
   
     | 
   
   
     | 
    – | 
    Diagnose
    turbulent boundary layer thickness 
     | 
     | 
   
   
     | 
   
   
     | 
    • | 
    Minimum
    depth H where a bulk Richardson number exceeds critical 
     | 
     | 
   
   
     | 
   
   
     | 
    value 
     | 
     | 
   
   
     | 
   
   
     | 
    • | 
    Turbulent
    boundary layer eddies can penetrate to depth H where the 
     | 
     | 
   
   
     | 
    fluid
    becomes stable relative to local buoyancy and velocity
