Evaporative fraction (EF) ranges from 1 to 0, from critical soil moisture (SCRIT) to wilting point (SWILT).
The importance of soil moisture for atmospheric con- ditions arises from the control it can exert on water and energy fluxes at the land surface, which alters the
Only in regions where soil moisture is the limiting factor for this partitioning can a dependence of water and energy fluxes on soil moisture be expected.
The presented framework has two major features that allow us to assess and quantify the impact of soil mois- ture on the energy fluxes.

ort to provide a possible dynamical explanation for the spatial concentration of energy fluxes in smaller and smaller subregions of the flow during the cascade.
What about the K41 energy cascade and the presence of an inertial range over which the energy flux is uniform?
Actually, some of the Fourier-space machinery developed by Kraichnan for closure, such as the use of the energy flux ?
k-n, Kraichnan showed that for n = 5/3 one obtains an inertial range with zero enstrophy flux and non-vanishing energy flux and that for n = 3 one obtains an inertial range with zero energy flux and non-vanishing enstrophy flux.
These would be the famous dual cascades of 2D turbulence if Kraichnan could show that the former range has a negative energy flux, while the lat- ter has a positive enstrophy flux.
