Fire as an interactive component of dynamic vegetation models
[1] Fire affects ecosystems by altering both their structure and the cycling of carbon and nutrients. The emissions from fires represent an important biogeochemical pathway by which the biosphere affects climate. For climate change studies it is important to model fire as a mechanistic climate-dependent process in dynamic global vegetation models (DGVMs) and the terrestrial ecosystem components...
متن کاملModeling Vegetation as a Dynamic Component in Soil-vegetation-atmosphere Transfer Schemes and Hydrological Models
[1] Vegetation affects the climate by modifying the energy, momentum, and hydrologic balance of the land surface. Soil-vegetation-atmosphere transfer (SVAT) schemes explicitly consider the role of vegetation in affecting water and energy balance by taking into account its physiological properties, in particular, leaf area index (LAI) and stomatal conductance. These two physiological properties ...
متن کاملInteractive visualization of dynamic models
Models in information systems are usually static in the sense that they can be visualized in a traditional way, using for example diagrams. In this paper we consider models which can be visualized only using what we call interactive visualization, that is, a kind of visualization where interaction with the user is essential. The interaction with the user triggers an action potentially changing ...
متن کاملA classification of landscape fire succession models: spatial simulations of fire and vegetation dynamics
A classification of spatial simulation models of fire and vegetation dynamics (landscape fire succession models or LFSMs) is presented. The classification was developed to provide a foundation for comparing models and to help identify the appropriate fire and vegetation processes and their simulation to include in coarse scale dynamic global vegetation models. Other uses include a decision tool...
متن کاملVariability of vegetation fire emissions
Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract Biomass burning has long been recognised as an important source of trace gases and aerosols in the atmosphere. The burning of vegetation has a repeating seasonal pattern, but the intensity of burning and the exact localisation of fires vary considerably f...
