|Tag||"Big leaf" Soil vegetation atmosphere SVAT model|
The process of energy flow and material circulation in the soil vegetation atmosphere system controls the microclimate environment of vegetation growth, which has an important impact on the growth of vegetation. At the same time, the exchange of energy and water between the surface and the atmosphere determines the intensity and stability of turbulence and diffusion in the boundary layer, and controls the lower boundary conditions of the climate system such as wind speed, temperature and humidity- Vegetation atmosphere transport model is very important to study and forecast climate change, hydrological cycle and ecological environment dynamics. J. W. Deardorff put forward the concept of "big leaf", added a layer of vegetation to the land surface simulation, and began to consider the ecological hydrological process of vegetation, thus forming the prototype of SVAT model. Isba is an interaction model among soil, biosphere and atmosphere, which was proposed by J. noilhan in 1989. It is used to simulate the exchange of heat, mass and momentum between land or water surface and upper atmosphere. The model is applied to the so-called independent development model. In the coupled model, the model provides lower boundary conditions for the atmospheric numerical weather forecast model, or higher boundary conditions for the distributed hydrological model.
