Abstract

We simulated the atmospheric planetary boundary layer (PBL) that develops above a locally deforested area of the Amazonian region, to emphasize the potential use of MKE to bridge between landscape discontinuities and mesoscale fluxes and, therefore, to parameterize mesoscale fluxes generated by such subgrid-scale landscape discontinuities in GCMs. Furthermore, this simulation indicates that local deforestation tends to increase vertical moisture flux in the PBL by the combined effect of turbulence and mesoscale circulations. As a result, local deforestation provides an atmospheric background that seems appropriate for the development of clouds and precipitation. -from Authors
