RISExponential Size Distributions of Raindrops and Vertical Air Motions Deduced from Vertically Pointing Doppler Radar Data Using a New Method
Publisher: American Meteorological Society
Abstract: Raindrop-size distributions and vertical air motions are deduced from vertically pointing C-band Doppler radar data by using a new method (described in Hauser and Amayenc, 1981) which assumes the raindrop sizes are ...
Retrieval of Cloud Water and Water Vapor Contents from Doppler Radar Data in a Tropical Squall Line
Publisher: American Meteorological Society
Abstract: This paper describes the retrieval of cloud water and water vapor contents from Doppler radar data. The convective part of a tropical squall line (22 June 1981) observed during the COPT 81 (Convection Profonde Tropicale ...
A Tropical Squall Line Observed during the COPT 81 Experiment in West Africa. Part II: Water Budget
Publisher: American Meteorological Society
Abstract: The relative contributions of the different processes involved in the water budget of the 22 June 1981 tropical squall line are investigated. The kinematic and thermodynamic fields derived from Doppler radar data are used ...
A Tropical Squall Line Observed during the COPT 81 Experiment in West Africa. Part III: Heat and Moisture Budgets
Publisher: American Meteorological Society
Abstract: The role of moist convective processes in the heat and moisture budgets of the 22 June 1981 tropical squall line is investigated. Detailed kinematic structure from Doppler radar observations, and thermodynamic and microphysical ...
A New Method for Deducing Hydrometeor-Size Distributions and Vertical Air Motions from Doppler Radar Measurements at Vertical Incidence
Publisher: American Meteorological Society
Abstract: Using the hypothesis of an exponential hydrometeor-size distribution characterized by the two classical intercept (N0) and slope (?) parameters, a method is presented for simultaneously deducing N0, ? and the vertical air ...
Comparison of Two Methods for the Retrieval of Thermodynamic and Microphysical Variables from Doppler Radar Measurements: Application to the Case of a Tropical Squall Line
Publisher: American Meteorological Society
Abstract: Microphysical and thermodynamic retrieval studies using a specified wind field can provide a means for analysing the different processes occurring within an observed precipitating system. Up to now, the retrieval of ...
The 12/13 January 1988 Narrow Cold-Frontal Rainband Observed during MFDP/FRONTS 87. Part II: Microphysics
Publisher: American Meteorological Society
Abstract: The microphysics of a narrow cold-frontal rainband (NCFR) observed during the MFDP/FRONTS87 experiment is investigated by using a microphysical retrieval model. The equations of evolution of the water substance and of the ...
The 12/13 January 1988 Narrow Cold-Frontal Rainband Observed during MFDP/FRONTS 87. Part I: Kinematics and Thermodynamics
Publisher: American Meteorological Society
Abstract: The kinematic and thermodynamic structure of a narrow cold-frontal rainband (NCFR) observed during the English?French?German MFDP/FRONTS 87 experiment is presented. Radiosonde data indicated a very weak convective instability ...
Comparison Study of a Second-Generation and of a Third-Generation Wave Prediction Model in the Context of the SEMAPHORE Experiment
Publisher: American Meteorological Society
Abstract: Numerical wave prediction models presently used in the meteorological institutes are still of two types: the so-called second-generation and third-generation models. In this paper, the authors present a comparison of the ...
