Experimental Study of an Artificial Thermal Plume in the Boundary Layer. Part III: Dynamic Structure within the Plume
Publisher: American Meteorological Society
Abstract: An experimental study of the dynamics within artificial thermal plumes rising in the boundary layer is presented. In this third part, measurements just above the heat source and aircraft investigations in the plume aloft ...
A Simple Parameterization of Land Surface Processes for Meteorological Models
Publisher: American Meteorological Society
Abstract: A parameterization of land surface processes to be included in mesoscale and large-scale meteorological models is presented. The number of parameters has been reduced as much as possible, while attempting to preserve the ...
GCM Grid-Scale Evaporation from Mesoscale Modeling
Publisher: American Meteorological Society
Abstract: This paper investigates the problem of aggregation of land surface properties in a large area comparable in size with a model grid box of a GCM. The study is based on 3D numerical results obtained for atmospheric situations ...
Comparative Study of Various Formulations of Evaporations from Bare Soil Using In Situ Data
Publisher: American Meteorological Society
Abstract: Vajious formulations of surface evaporation are tested against in situ data collected over a plot of loamy bare ground. Numerical simulations lasting seven days are compared with observations of near-surface water content ...
Inclusion of Gravitational Drainage in a Land Surface Scheme Based on the Force-Restore Method
Publisher: American Meteorological Society
Abstract: This paper presents a simple parameterization of gravitational drainage for land surface schemes describing soil water transfers according to the force-restore method of Deardorff. A one-year time series of observed soil ...
Sequential Assimilation of Soil Moisture from Atmospheric Low-Level Parameters. Part I: Sensitivity and Calibration Studies
Publisher: American Meteorological Society
Abstract: This paper and its companion report on the development of a sequential assimilation technique based upon optimum interpolation in order to initialize soil moisture in atmospheric models. A previous study by Mahfouf has ...
Sequential Assimilation of Soil Moisture from Atmospheric Low-Level Parameters. Part II: Implementation in a Mesoscale Model
Publisher: American Meteorological Society
Abstract: A sequential assimilation technique based upon optimum interpolation is developed to initialize soil moisture in atmospheric models. Soil moisture increments are linearly related to forecast errors of near-surface atmospheric ...
An Experiment with an Advanced Surface Parameterization in a Mesobeta-Scale Model. Part III: Comparison with the HAPEX-MOBILHY Dataset
Publisher: American Meteorological Society
Abstract: In this last part, a detailed comparison of the model predictions with all the HAPEX-MOBILHY dataset available within a mesoscale subdomain is carried out. The simulation subdomain encompasses a fraction of a pine forest ...
Retrieving the Root-Zone Soil Moisture from Surface Soil Moisture or Temperature Estimates: A Feasibility Study Based on Field Measurements
Publisher: American Meteorological Society
Abstract: The bulk soil water content must be estimated accurately for short- and medium-term meteorological modeling. A method is proposed to retrieve the total soil moisture content as well as the field capacity from observed ...
Experimental Study of an Artificial Thermal Plume in the Boundary Layer. Part II: Some Aspects of the Plume Thermodynamical Structure
Publisher: American Meteorological Society
Abstract: Some aspects of the mean and turbulent structures of artificial thermal plumes in the boundary layer (BL) are presented. This analysis is based mainly on measurements with an instrumented aircraft. As initial conditions ...
