| Resumo | Because fires have strong effects on biogeochemical cycles and important relations with dominant characteristics of the land surface, it is important that biome models are able to account for fire occurrence. To this end, the CPTEC-PBM (Brazilian Center for Weather Forecast and Climate Studies - Potential Biome Model) used to study climate-vegetation interactions, is being improved to account for fire activity. We first concentrate on regions of savannas, where fire activity is highest and fire effects are particularly important. As shown by satellite-based data, the global patterns of fire occurrence and savannas are very similar. Compared to the relatively slow processes of vegetation carbon uptake and growth, fast mortality and biomass consumption by fires may favor grasses and reduce trees coverage. In order to account for large spatial and temporal patterns of natural fire occurrence in savannas, we have made two main assumptions. First, lightning is the most important source of ignition for natural fires. Second, over continental areas in the tropics, lightning is mainly related to the zonal flux of humidity. The parameterization of fire occurrence was then built on a simple empirical relation based on combined information on average and intra-annual variance of the zonal wind. The implementation of this new relation improved the formulation and the results of the CPTEC-PBM. In addition to account for a relevant process in savannas, the accuracy allocating major biomes in India and Southeast Asia is now substantially higher than in previous studies. Important broad implications of these results include the potential for improved analyses of the relations between climate and vegetation, such as projections of the impacts of different climate conditions on land surface, and the impacts of land-cover changes on climate. | ||||||
