Since the earth’s surface is always heterogeneous to some extent, the topography plays a significant role in the surface fluxes of momentum, heat, humidity and other quantities including dust and pollen. The variation of these fluxes as a result of land-atmosphere interactions has important implications for the hydrological cycle. These processes become even more relevant in desert – like, arid environments, where water management is essential for agriculture.
