Influence of Soil Moisture on the Planetary Boundary Layer and on Cumulus Convection Over an Isolated Mountainm Part I. Observations, The
Contributor:Zhou, Xin; Geerts, Bart
Data collected around the Santa Catalina Mountains in Arizona as part of the Cumulus Photogrammetric, In Situ and Doppler Observations (CuPIDO) experiment during the 2006 summer monsoon season are used to investigate the ...
Boundary layer turbulence and orographic precipitation growth in cold clouds : Evidence from profiling airborne radar data
Contributor:Geerts, Bart; Miao, Qun; Yang, Yang
Airborne vertically pointing Doppler radar data collected in 10 winter storms over the Medicine Bow Range in Wyoming are used to examine the importance of boundary layer (BL) turbulence for orographic precipitation growth. ...
Airborne measurements of terrain-induced pressure perturbations
Contributor:Parish, T. R.; Geerts, Bart
Airborne measurement of the horizontal pressure field using differential GPS technology has been established during the last few years. Accurate aircraft measurement of the horizontal pressure gradient force requires an ...
Vertically pointing airborne Doppler radar observations of Kelvin-Helmholtz billows
Contributor:Geerts, Bart; Miao, Qun
A train of Kelvin-Helmholtz billows in a deep stratiform cloud over a mountain range is documented using data from a high-resolution vertically pointing airborne Doppler radar. The billows had a spacing of 2-2.5 km and a ...
Airborne profiling radar study of the impact of glaciogenic cloud seeding on snowfall from winter orographic clouds, An
Contributor:Geerts, Bart; Miao, Q.; Yang, Y.; Rasmussen, R.; Breed, D.
Data from an airborne vertically pointing millimeter-wave Doppler radar are used to study the cloud microphysical effect of glaciogenic seeding of cold-season orographic clouds. Fixed flight tracks were flown downstream ...
Numerical study of the evolving convective boundary layer and orographic circulation around the Santa Catalina Mountains in Arizona, Part I. Circulation without deep convection, A
Contributor:Demko, J. C.; Geerts, Bart
The daytime evolution of the thermally forced boundary layer (BL) circulation over an isolated mountain, about 30 km in diameter and 2 km high, is examined by means of numerical simulations validated with data collected ...
Dryline in Southeast Wyoming. Part II : Airborne In Situ and Raman LiDAR Observations, A
Contributor:Bergmaier, Philip T.; Geerts, Bart; Wang, Zhien; Liu, Bo; Campbell, Patrick C.
Part I of this study describes the mesoscale structure of a dryline over southeastern Wyoming. This dryline formed just east of the western rim of the high plains on 22 June 2010 and became more defined as it progressed ...
Simulating the IHOP_2002 Fair-Weather CBL with the WRF-ARW-Noah Modeling System, Part II. Structures from a Few Lilometers to 100 km Across
Contributor:Lemone, Margaret A.; Chen, Fei; Tewari, Mukul; Dudhia, Jimy; Geerts, Bart; Miao, Qun; Coulter, Richard L.; Grossman, Robert L.
Fair-weather data along the May-June 2002 International H2O Project (IHOP_2002) eastern track and the nearby Argonne Boundary Layer Experiments (ABLE) facility in southeast Kansas are compared to numerical simulations to ...
Observations of the Evolution of the Nocturnal and Convective Boundary Layers and the Structure of Open-Celled Convection on 14 June 2002
Contributor:Bennett, Lindsay J.; Weckwerth, Tammy M.; Blyth, Alan M.; Geerts, Bart; Miao, Qun; Richardson, Yvette P.
The Boundary Layer Evolution (BLE) missions of the International H2O Project (IHOP_2002) were designed to provide comprehensive observations of the distribution of water vapor in the quiescent boundary layer and its evolution ...
2012 Unidata Users Workshop Navigating Earth System Science Data
Contributor:Lazarus, S. M.; Collllins, J. M.; Baxter, M. A.; Hanks, A. C.; Whittaker, T. M.; Tyle, K. R.; Cecelslski, S. F.; Geerts, Bart; Ramamurthy, M. K.
The Unidata Program Center (UPC) worked with the Unidata Users Committee to organize triennial summer workshops on topics of interest to the Unidata community. The 2012 workshop theme, entitled 'navigating Earth system ...
