 This is particularly useful in simulations of convective boundary layers where the local near-surface wind is expected to close to zero, e.g. in urban environments when the present buildings create spots of stagnant air. {{{w_lfc}}} accounts for the dominant eddies close to the surface that cannot be resolved by the LES model and increases {{{u_h}}} by a small amount. When using the land surface scheme, this might prevent the surface sensible heat flux from dropping to zero under no-wind conditions.
