We proposed a surface flux scheme based on the Monin-Obukhov similarity for finite volume models. The scheme solves a negative bias existing in conventional surface flux schemes. In the conventional schemes, the model prognostic variables are used as the center point value in the model grid to ...
The selection of stability classification has a critical impact on the calculated ambient pollutant concentrations. In this thesis, two methods of atmospheric stability class determination, Pasquill/Turner classification scheme and Monin-Obukhov Length Method, are used for Environmental Protection Agency Model...
(2012) revised the formulations of the fifth-generation Pennsylvania State University-National Center for Atmospheric Research Mesoscale Model (MM5) surface layer scheme by introducing more consistent formulations, such as reducing the thresholds of certain variables and change in the upper limit of ...
An attempt has been made to extend this scheme to incorporate the similarity functions having a theoretically consistent free convection limit. Further, the performance of the scheme is evaluated using observational data from two different sites. The proposed scheme is simple, non-iterative and ...

In the new scheme,Obukhov stability parameter is directly parameterized through bulk Richardson number,aerodynamic roughness length and heat roughness length,and thus the flux can be derived by using the universal functions of H gstr m(1996)and Beljaars et al. 该方案直接用整体理查森数、空气动力学...
During the last few decades, several two-source evapotranspiration (ET) models have been developed by exploiting satellite datasets in conjunction with meteorological observations to estimate fluxes at different spatio-temporal scales. However, the complex parameterization scheme intrinsic to those models as...
