Local land-atmosphere coupling involves the interactions between the land-surface and the atmospheric boundary layer (ABL), and in turn with the free atmosphere above. Initiation of fair-weather cumulus requires an increase in relative humidity at the ABL top, and depends on a number of processes, some opposing each other. Those processes include the evolution of surface fluxes, sub-surface heat and moisture transport, surface-layer turbulence, boundary-layer development, and warm- and dry-air entrainment into the ABL from the free atmosphere above. Following an analytical development, we use modeling and observational data sets to examine this question.
