RISExperimental Study of an Artificial Convective Plume Initiated from the Ground
Publisher: American Meteorological Society
Abstract: An experimental project on convective plumes initiated from the ground by an exceptionally powerful artificial heat source has been carried out. The heat source consisted of 97 oil burners releasing a total power of 600 ...
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 ...
Space–Time Description of Nonstationary Trapped Lee Waves Using ST Radars, Aircraft, and Constant Volume Balloons during the PYREX Experiment
Publisher: American Meteorological Society
Abstract: The third intensive observation period (IOP3) of PYREX was a case of strong lee waves generated by a southerly wind crossing the Pyrenees chain. Upstream radiosounds and measurements obtained by aircraft along the chain ...
Infrared Imagery Applied to A Large Buoyant Plume
Publisher: American Meteorological Society
Abstract: The possibility of applying infrared imagery to the study of a large, hot plume materialized by carbon particles resulting from the incomplete combustion of fuel oil is investigated. In a specific case (the PROSERPINE ...
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 ...
Dynamic Characteristics of Regional Flows around the Pyrénées in View of the PYREX Experiment. Part II: Solution of a Linear Model Compared to Field Measurements
Publisher: American Meteorological Society
Abstract: This paper considers a linear hydrostatic model of a stable, uniform, constant rotational airflow over three- dimensional, elliptic, cross-sectional families of mountains in a z system. The surface pressure and the winds ...
Momentum Budget over the Pyrénées: The PYREX Experiment
Publisher: American Meteorological Society
Abstract: Although the qualitative influence of mountains over the atmosphere has been known for a long time, numerous deficiencies, linked to orography, are still noted, either in forecasts by regional models, or in the long-term ...
Experimental Study of an Artificial Thermal Plume in the Boundary Layer. Part I: Flow Characteristics near the Heat Source
Publisher: American Meteorological Society
Abstract: The work reported here describes the environmental impact of emitting about 1000 MW of dry heat from a concentrated source into the atmosphere. It is based on a large field program conducted jointly by the Centre de ...
Comparison of Radar Reflectivity and Vertical Velocity Observed with a Scannable C-Band Radar and Two UHF Profilers in the Lower Troposphere
Publisher: American Meteorological Society
Abstract: A C-band meteorological Doppler radar has been used to investigate the dynamic processes and the coherent organizations within a clear air atmospheric boundary layer (ABL). Depending on the atmospheric conditions, this ...
