What is Simulated Impacts of Historical Land Cover Changes on Global Climate in Northern Winter about?

This ten-year general circulation model experiment compared a simulation where land surface boundary conditions were represented by observed, present day land cover to a simulation where the surface was represented by natural, potential land cover conditions. As a result of these estimated changes in historical land cover, signi®cant temperature and hydrology changes aected tropical land surfaces, where some of the largest historical disruptions in total vegetation biomass have occurred. Also of considerable interest because of their broad scope and magnitude were changes in high-latitude Northern Hemisphere winter climate which resulted from changes in tropical convection, upper-level tropical out ̄ow, and the generation of low-frequency tropical waves which propagated to the extratropics. These eects combined to move the Northern Hemisphere zonally averaged westerly jet to higher latitudes, broaden it, and reduce its maximum intensity. Low-level easterlies were also reduced over much of the tropical Paci®c basin while positive anomalies in convective precipitation occurred in the central Paci®c. Globally averaged changes were small. Comparisons of recent, observed trends in tropi
