RISUnderstanding the Mechanisms behind the Northward Extension of the West African Monsoon during the Mid-Holocene
Publisher: American Meteorological Society
Abstract: AbstractUnderstanding the West African monsoon (WAM) dynamics in the mid-Holocene (MH) is a crucial issue in climate modeling, because numerical models typically fail to reproduce the extensive precipitation suggested by ...
An Atmospheric Soliton Observed with Doppler Radar, Differential Absorption Lidar, and a Molecular Doppler Lidar
Publisher: American Meteorological Society
Abstract: Airborne Leandre II differential absorption lidar (DIAL), S-band dual-polarization Doppler radar (S-Pol), and Goddard Lidar Observatory for Winds (GLOW) Doppler lidar data are used, in conjunction with surface mesonet and ...
An Observational Study of Convection Initiation on 12 June 2002 during IHOP_2002
Publisher: American Meteorological Society
Abstract: The International H2O Project (IHOP_2002) was designed to sample the three-dimensional time-varying moisture field to better understand convective processes. Numerous research and operational water vapor measuring systems ...
Kinematic and Moisture Characteristics of a Nonprecipitating Cold Front Observed during IHOP. Part II: Alongfront Structures
Publisher: American Meteorological Society
Abstract: Kinematic and thermodynamic structures of a nonprecipitating cold front observed in west-central Kansas on 10 June 2002 during the International H2O Project (IHOP) are examined with dropsondes and airborne instrumentation ...
Dryline on 19 June 2002 during IHOP. Part I: Airborne Doppler and LEANDRE II Analyses of the Thin Line Structure and Convection Initiation
Publisher: American Meteorological Society
Abstract: The evolution and finescale structure of a dryline that initiated a line of thunderstorms is presented. Both the along-line variability and mean vertical structure were examined using data collected by an airborne Doppler ...
Kinematic and Moisture Characteristics of a Nonprecipitating Cold Front Observed during IHOP. Part I: Across-Front Structures
Publisher: American Meteorological Society
Abstract: A wide array of ground-based and airborne instrumentation is used to examine the kinematic and moisture characteristics of a nonprecipitating cold front observed in west-central Kansas on 10 June 2002 during the International ...
Pressure Measurements Using an Airborne Differential Absorption Lidar. Part I: Analysis of the Systematic Error Sources
Publisher: American Meteorological Society
Abstract: Systematic error sources that require correction when making remote airborne measurements of the atmospheric pressure field in the lower troposphere, using an oxygen differential absorption lidar, are analyzed. A detailed ...
Observations of the 11 June Dryline during IHOP_2002—A Null Case for Convection Initiation
Publisher: American Meteorological Society
Abstract: The detailed analysis of the three-dimensional structure of a dryline observed over the Oklahoma panhandle during the International H2O Project (IHOP_2002) on 11 June 2002 is presented. High-resolution observations obtained ...
Water Vapor–Forced Greenhouse Warming over the Sahara Desert and the Recent Recovery from the Sahelian Drought
Publisher: American Meteorological Society
Abstract: he Sahel region of West Africa experiences decadal swings between periods of drought and abundant rainfall, and a large body of work asserts that these variations in the West African monsoon are a response to changes in ...
Comparison of Raman Lidar Observations of Water Vapor with COSMO-DE Forecasts during COPS 2007
Publisher: American Meteorological Society
Abstract: ater vapor measurements with the multiwavelength Raman lidar Backscatter Extinction Lidar-Ratio Temperature Humidity Profiling Apparatus (BERTHA) were performed during the Convective and Orographically-induced Precipitation ...
