RISA Comparison of Three Methods for Measuring Mixing-Layer Height
Publisher: American Meteorological Society
Abstract: Temperature profile, lidar and sodar results for determination of mixing-layer heights during October 1977 are compared. While the overall agreement was good, systematic differences do appear, particularly in early morning ...
The Dependence of Canyon Winds on Surface Cooling and External Forcing in Colorado's Front Range
Publisher: American Meteorological Society
Abstract: The atmospheric katabatic flow in the foothills of the Front Range of the Rocky Mountains has been monitored by a network of towers and sodars for several years as part of the ASCOT program. The dependence of the outflow ...
Climatology of the Low-Level Jet at the Southern Great Plains Atmospheric Boundary Layer Experiments Site
Publisher: American Meteorological Society
Abstract: A unique dataset obtained with combinations of minisodars and 915-MHz wind profilers at the Atmospheric Boundary Layer Experiments (ABLE) facility in Kansas was used to examine the detailed characteristics of the nocturnal ...
A Comparison of Nocturnal Drainage Flow in Three Tributaries
Publisher: American Meteorological Society
Abstract: The characteristics of tributary drainage flow in stable, nocturnal conditions in three closely located tributaries are compared. The orientation of the tributaries with respect to Kimball Creek, into which they drain, ...
Nighttime Valley Waves
Publisher: American Meteorological Society
Abstract: This paper describes a regular oscillation observed in nighttime drainage airflow in a valley under relatively light upper-level wind conditions. The period of these oscillations is about 20 minutes with at least one ...
Tributary, Valley and Sidewall Air Flow Interactions in a Deep Valley
Publisher: American Meteorological Society
Abstract: Field experiments measuring nocturnal tributary flows have shown complex internal structure. Variations in the flow range from short-term (8?16 min) oscillations (related to tributary/valley flow interactions) to long-term ...
Simulating the IHOP_2002 Fair-Weather CBL with the WRF-ARW–Noah Modeling System. Part II: Structures from a Few Kilometers to 100 km across
Publisher: American Meteorological Society
Abstract: 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 ...
Simulating the IHOP_2002 Fair-Weather CBL with the WRF-ARW–Noah Modeling System. Part I: Surface Fluxes and CBL Structure and Evolution along the Eastern Track
Publisher: American Meteorological Society
Abstract: Fair-weather data from the May?June 2002 International H2O Project (IHOP_2002) 46-km eastern flight track in southeast Kansas are compared to simulations using the advanced research version of the Weather Research and ...
Influence of Land Cover and Soil Moisture on the Horizontal Distribution of Sensible and Latent Heat Fluxes in Southeast Kansas during IHOP_2002 and CASES-97
Publisher: American Meteorological Society
Abstract: Analyses of daytime fair-weather aircraft and surface-flux tower data from the May?June 2002 International H2O Project (IHOP_2002) and the April?May 1997 Cooperative Atmosphere Surface Exchange Study (CASES-97) are used ...
Overview of the Cumulus Humilis Aerosol Processing Study
Publisher: American Meteorological Society
Abstract: The primary goal of the Cumulus Humilis Aerosol Processing Study (CHAPS) was to characterize and contrast freshly emitted aerosols below, within, and above fields of cumuli, and to study changes to the cloud microphysical ...
