Sentences with phrase «scale vegetation model»
However, global - scale vegetation model development has strongly focused on productivity processes whereas, apart from major disturbances such as fire, the dynamics of carbon turnover have been largely ignored.

The model allowed Bonachela and his colleagues to apply small - scale observational data broadly to understand how rainfall influences vegetation growth and persistence in the presence and absence of termites across an entire ecosystem.
Adding chlorofyll fluorescence to vegetation models provides means to understand photosynthesis better at a global scale and improve its modelling.
In this work we implemented a chlorophyll fluorescence model developed at leaf scale to a global vegetation model JSBACH and we evaluated the model performance in terms of photosynthesis and chlorophyll fluorescence.
As the temporal scale is extended, the development of dynamic vegetation models, which respond to climate and human land use as well as other changes, is a central issue.
The researchers used a climate - vegetation model that showed (like several similar studies) a clear increase in Amazonian drought following a global average temperature rise — leading to a large - scale die - back of rainforest, switching to grassland and savanna climate suitability.
Modelling interactions between terrestrial and atmospheric systems requires coupling successional models to biogeochemical models and physiological models that describe the exchange of water and energy between vegetation and the atmosphere at fine time - scales.
The meeting will mainly cover the following themes, but can include other topics related to understanding and modelling the atmosphere: ● Surface drag and momentum transport: orographic drag, convective momentum transport ● Processes relevant for polar prediction: stable boundary layers, mixed - phase clouds ● Shallow and deep convection: stochasticity, scale - awareness, organization, grey zone issues ● Clouds and circulation feedbacks: boundary - layer clouds, CFMIP, cirrus ● Microphysics and aerosol - cloud interactions: microphysical observations, parameterization, process studies on aerosol - cloud interactions ● Radiation: circulation coupling; interaction between radiation and clouds ● Land - atmosphere interactions: Role of land processes (snow, soil moisture, soil temperature, and vegetation) in sub-seasonal to seasonal (S2S) prediction ● Physics - dynamics coupling: numerical methods, scale - separation and grey - zone, thermodynamic consistency ● Next generation model development: the challenge of exascale, dynamical core developments, regional refinement, super-parametrization ● High Impact and Extreme Weather: role of convective scale models; ensembles; relevant challenges for model development
Adding chlorofyll fluorescence to vegetation models provides means to understand photosynthesis better at a global scale and improve its modelling.
Extrapolated to global scale, these are termed Dynamic Global Vegetation Models (DGVMs, see Glossary).
Specific research topics include carbon dioxide, methane and water fluxes and their reservoirs in vegetation and soil, transport in atmosphere, and model - data fusion using advanced numerical methods.The research is based on numerical modelling, from local to global scale with focus on northern regions.
