RISThe West African Squall Line Observed on 23 June 1981 during COPT 81: Kinematics and Thermodynamics of the Convective Region
Publisher: American Meteorological Society
Abstract: The squall line observed during the night of 23-24 June 1981 was one of the most intense events during the COPT 81 (COnvection Profonde Tropicale) experiment, conducted in May and June 1981 at Korhogo in the northern Ivory ...
Retrieval of Thermodynamic Fields from Multiple-Doppler Radar Data Using the Equations of Motion and the Thermodynamic Equation
Publisher: American Meteorological Society
Abstract: A new method is proposed to determine completely the thermodynamic fields from the relative pressure and temperature perturbations, retrieved from the processing of multiple-Doppler radar data through the equations of ...
Failed Cyclogenetic Evolution of a West African Monsoon Perturbation Observed during AMMA SOP-3
Publisher: American Meteorological Society
Abstract: The so-called ?perturbation D? was a nondeveloping West African disturbance observed near Dakar (Senegal) during special observing period (SOP) 3 of the African Monsoon Multidisciplinary Analysis (AMMA) in September 2006. ...
Case Study of a Developing African Easterly Wave during NAMMA: An Energetic Point of View
Publisher: American Meteorological Society
Abstract: The West African perturbation that subsequently evolved into Hurricane Helene (2006) during NASA?s African Monsoon Multidisciplinary Analysis (NAMMA), 15 August?14 September 2006, and AMMA?s third special observing period ...
Comparison between Two Case Studies of Developing and Nondeveloping African Easterly Waves during NAMMA and AMMA/SOP-3: Absolute Vertical Vorticity Budget
Publisher: American Meteorological Society
Abstract: Two West African disturbances observed in August and September 2006 during the National Aeronautics and Space Administration African Monsoon Multidisciplinary Analysis (NAMMA) and the Special Observing Period 3 (AMMA/SOP-3) ...
Structure and Evolution of Hurricane Claudette on 7 September 1991 from Airborne Doppler Radar Observations. Part I: Kinematics
Publisher: American Meteorological Society
Abstract: On 7 September 1991, an experiment was conducted with the two National Oceanic and Atmospheric Administration (NOAA) WP-3D research aircraft to investigate the inner-core region of Hurricane Claudette. Both aircraft carried ...
Structure and Evolution of Hurricane Claudette on 7 September 1991 from Airborne Doppler Radar Observations. Part II: Thermodynamics
Publisher: American Meteorological Society
Abstract: In Part I, the kinematic and precipitating fields of Hurricane Claudette have been analyzed, using airborne Doppler radar data collected on 7 September 1991 by the two National Oceanic and Atmospheric Administration (NOAA) ...
Initialization of a Cloud-Resolving Model with Airborne Doppler Radar Observations of an Oceanic Tropical Convective System
Publisher: American Meteorological Society
Abstract: Doppler radar?derived fields of wind and reflectivity, retrieved temperature perturbations, estimated water vapor, and cloud water contents are used to initialize a nonhydrostatic cloud-resolving model. Airborne Doppler ...
Single-Doppler Observations of a West African Squall Line on 27-28 May 1981 during COPT 81: Kinematics, Thermodynamics and Water Budget
Publisher: American Meteorological Society
Abstract: A large and intense West African squall line has been observed during the night of 27/28 May 1981 at Korhogo (in the north of Ivory Coast) during the COPT 81 experiment. The environmental conditions in which it occurred ...
Extended Velocity Track Display (EVTD): An Improved Processing Method for Doppler Radar Observations of Tropical Cyclones
Publisher: American Meteorological Society
Abstract: The authors present an improved version of the velocity track display (VTD) method, proposed by Lee et al., to deduce the primary vortex circulation in hurricanes from airborne Doppler radar data obtained during straightline ...
