This paper presents a comprehensive revision of the classical, local theory of the convective heat mass transfer and further advancement of the recently developed nonlocal theory with particular attention to very rough and complex land surfaces, including mountainous landscapes. Recall that the classical theory employed the concept of the near-surface viscous layer, therefore neglected the role of the surface roughness, and strongly underestimated the surface fluxes. The key points of the new theory are (i) turbulent mixing caused by large-scale semi-organised eddies (completely overlooked in the classical theory but accounted for in modern non-local theories), (ii) interaction between large eddies and surface roughness elements up to very big obstacles such
