Title
Two-Source Micro-Advection Turbulent Heat Fluxes Model For Partially Vegetated Surfaces
Abstract
A novel method was proposed to simulate heat fluxes above partially vegetated surfaces. The interaction of the heat fluxes between the two components (soil and foliage) in canopy was modeled using the concept of "micro-advection", which refers to small-scale movement of air in a restricted area. To adjust the heat balance of the local plant-atmosphere system is the main function of the micro-advection in this model, i.e., part of the heat emanated from soil surface is transported to the foliage surface and then consumed by the transpiration effect of the leaves in this process. The magnitude of this part of heat transport between components can be estimated from the temperature gradient between them as well as the diffusion coefficients of them. Therefore, the overall effect of the micro-advection is to diminish the total sensible heat flux and increase the level of total latent heat flux. This model was validated using the data of row crop, and the result showed good agreement with field turbulent measurements.
