Covariance structures for point sources in various locations.

Left column: diff=const, vel=0 [benchmark of DRL result].
Middle column: diff = const, MA climatological velocity
Right column: MA climatological velocity and diffusivity
 

                     Ah = const  , V = 0          Ah = const, MA V field         MA V , Ah


 
 

Velocity vectors overlayed on the diffusivity field.
