Use of Wind Profiler Estimates of Significant Moisture Gradients to Improve Humidity Profile Retrieval
Publisher: American Meteorological Society
Abstract: A method is presented to obtain a high-vertical-resolution humidity profile if the location and strength of only a few significant segments of the humidity gradient profile are known. The method is based on a previously ...
The Rapid Morning Boundary-Layer Transition
Publisher: American Meteorological Society
Abstract: Even slight terrain inhomogeneities can cause large horizontal variations in the clear, stably stratified, nocturnal boundary layer largely through cold air drainage. By early morning the valleys and depressions can be ...
Moisture Profiling of the Cloudy Winter Atmosphere Using Combined Remote Sensors
Publisher: American Meteorological Society
Abstract: A new method for deriving profiles of tropospheric water vapor and liquid water from a combination of ground-based remote sensors was applied and tested under winter conditions in Colorado. The method is an extension of ...
Wave and Turbulence Structure in a Shallow Baroclinic Convective Boundary Layer and Overlying Inversion
Publisher: American Meteorological Society
Abstract: Data from the Boulder Atmospheric Observatory (BAO) are used to investigate the wave and turbulence structure of the convective atmospheric mixed layer and the overlying inversion. Three cases are discussed, one in ...
Midtroposphere Wind Speed Spectra from Long-Term Wind Profiler Measurements
Publisher: American Meteorological Society
Abstract: This study of a 5-yr continuous record of midtropospheric horizontal wind components from a radar wind profiler operating at Fleming, Colorado, shows a broad spectral peak centered around a period of 1 week and a minimum ...
Radio Acoustic Sounding System Observations of an Arctic Front
Publisher: American Meteorological Society
Abstract: A radio acoustic sounding system (RASS), coupled with the NOAA/Wave Propagation Laboratory 915-MHz wind profiler, observed an arctic front and arctic air mass that passed over Denver, Colorado, between 1 and 5 February ...
Spectral Characteristics of the Convective Boundary Layer Over Uneven Terrain
Publisher: American Meteorological Society
Abstract: The paper describes a convective boundary layer experiment conducted in April 1978 at the Boulder Atmospheric Observatory, and examines the spectral behavior of wind velocity and temperature from the Observatory's 300 m ...
An Evaluation of Wind Profiler, RASS, and Microwave Radiometer Performance
Publisher: American Meteorological Society
Abstract: Several ground-based remote Sensors were operated together in Colorado during February and March 1991 to obtain continuous profiles of the kinematic and thermodynamic structure of the atmosphere. Instrument performance is ...
