Abstract

Surface momentum, sensible heat, and latent heat fluxes are critical for atmospheric processes such as clouds and precipitation, and are parameterized in a variety of models ranging from cloud-resolving models to large-scale weather and climate models. However, direct evaluation of the parameterization schemes for these surface fluxes is rare due to limited observations. This study takes advantage of the long-term observations of surface fluxes collected at the Southern Great Plains site by the Department of Energy Atmospheric Radiation Measurement program to evaluate the six surface flux parameterization schemes commonly used in the Weather Research and Forecasting (WRF) model and three U.S. general circulation models (GCMs). The unprecedented 7-yr-long measurements by the eddy correlation (EC) and energy balance Bowen ratio (EBBR) methods permit statistical evaluation of all six parameterizations under a variety of stability conditions, diurnal cycles, and seasonal variations. The statistical analyses show that the momentum flux parameterization agrees best with the EC observations, followed by latent heat flux, sensible heat flux, and evaporation ratio/Bowen ratio. The overall performance of the parameterizations depends on atmospheric stability, being best under neutral stratification and deteriorating toward both more stable and more unstable conditions. Further diagnostic analysis reveals that in addition to themore »« less

Evaluation of Surface Flux Parameterizations with Long-Term ARM Observations

Satellite-derived surface characterization and surface fluxes across the Southern Great Plains Cloud and Radiation Testbed Site.

Conference Gao, W ; Coulter, R L ; Lesht, B M ; ...

Atmospheric processes in the lower boundary layer are strongly modulated by energy and mass fluxes from and to the underlying surface. The atmosphere-surface interactions usually occur at small temporal (seconds to minutes) and spatial (centimeters to meters) scales, which causes difficulties with including surface processes in atmospheric models, which can only handle much larger scales (kilometers). Developing schemes to characterize spatial variabilities in surface fluxes over heterogeneous surfaces for a regionally representative surface flux that can be correctly used in atmospheric models becomes an important issue.

Quantifying physical parameterization uncertainties associated with land-atmosphere interactions in the WRF model over Amazon

Journal Article Wang, Chen ; Qian, Yun ; Duan, Qingyun ; ... - Atmospheric Research

The Weather Research and Forecasting (WRF) model can be used to diagnose regional land-atmosphere (L-A) coupling strength in the absence of sufficient observations but subjected to uncertainties associated with model physical parameterizations. In this study, we propose a framework to quantify and reduce model physical parameterization uncertainties associated with surface fluxes and L-A coupling. An ensemble of WRF simulations with different physical schemes is used to simulate surface fluxes and land-atmosphere coupling strength over the Amazon region. The physical parameterizations investigated include cloud microphysics (MP), land surface processes (LSM), planetary boundary layer (PBL), surface layer (SL), and cumulus (CU). Wemore »« less

Estimating clear-sky regional surface fluxes in the southern great plains atmospheric radiation measurement site with ground measurements and satellite observations.

Journal Article Gao, W ; Coulter, R L ; Lesht, B M ; ... - J. Appl. Meteorol.

The authors compared methods for estimating surface fluxes under clear-sky conditions over a large heterogeneous area from a limited number of ground measurements and from satellite observations using data obtained from the southern Great Plains Cloud and Radiation Testbed (CART) site, an area of approximately 350 km x 400 km located in Kansas and Oklahoma. In situ measurements from 10 energy balance Bowen ratio (EBBR) stations showed large spatial variations in latent and sensible heat fluxes across the site because of differences in vegetation and soil conditions. This variation was reproduced by a model for parameterization of subgrid-scale (PASS) surfacemore »« less

A technique for determining the spatial and temporal distributions of surface fluxes of heat and moisture over the Southern Great Plains Cloud and Radiation Testbed

Journal Article Doran, J C ; Hubbe, J M ; Liljegren, J C ; ... - Journal of Geophysical Research

Land surface parameterization schemes such as the Simple Biosphere Model (SiB2) have found considerable use in climate simulation models, where they provide lower boundary conditions in the form of surface sensible and latent heat fluxes. A methodology is described to apply models of this type at high resolution, using data from the Department of Energy{close_quote}s Cloud and Radiation Testbed in Oklahoma and Kansas, to determine the spatial variations of heat fluxes over the domain and to determine area-weighted flux averages for use in single-column model studies. Data from a dense array of meteorological instruments are interpolated to provide the wind,more »« less
