The impact of the parameterization of heterogeneous vegetation on the modeled large‐scale circulation in CCM3‐BATS

This letter reports evidence of an unexpected large change in the planetary‐scale circulation as a consequence of modifying the land cover within the Community Climate Model (CCM3). Three 10‐year simulations were analyzed using (i) default land cover, i.e., a single dominant vegetation in each land grid cell; (ii) aggregate land cover that includes a representation of subpixel heterogeneity; and (iii) aggregate land cover for aerodynamic …
