Asymmetric Removal of Temperature Inversions in a High Mountain Valley
Publisher: American Meteorological Society
Abstract: During July 1985 the transition from nighttime to daytime wind regimes was studied in a steep-sided, broad mountain valley at about 2200 m MSL, in southeastern Wyoming. An array of surface weather stations and plot balloon ...
Horizontal Roll and Boundary-Layer Interrelationships Observed over Lake Michigan
Publisher: American Meteorological Society
Abstract: On 7, 9 and 10 January 1981 some 35 hours of organized horizontal roll convection in the boundary layer over lake Michigan were probed with two airplanes and two radars from the University of Chicago Lake Snow Project. ...
Mesoscale Frequencies and Seasonal Snowfalls for Different Types of Lake Michigan Snow Storms
Publisher: American Meteorological Society
Abstract: Members of the Cloud Physics Laboratory, University of Chicago, have identified three different mesoscale organization patterns of lake-effect snow storms over Lake Michigan: multiple wind-parallel bands, single midlake ...
A Single Doppler Radar Study of Horizontal-Roll Convection in a Lake-Effect Snow Storm
Publisher: American Meteorological Society
Abstract: The boundary-layer structure and circulation over Lake Michigan were probed with a Doppler radar and an aircraft during a lake-effect snow storm on 9 December 1978. Evidence is presented that observed wind-parallel echo ...
Atmospheric Contribution to the Time-Dependent Geopotential
Publisher: American Meteorological Society
Abstract: Integral expressions for the geopotential of the earth plus atmosphere are derived from the solution of Poisson's equation. The series of integrals involves position-weighted density integrated over all space exterior to ...
An Experimental Study of the Production of Ice Crystals by a Twin-Turboprop Aircraft
Publisher: American Meteorological Society
Abstract: The University of Wyoming King Air (KA) research aircraft was used in controlled, in situ experiments to determine whether or not, and under what cloud and aircraft operating conditions, a twin-turboprop aircraft would ...
95-GHz Polarimetric Radar Measurements of Orographic Cap Clouds
Publisher: American Meteorological Society
Abstract: The use of millimeter-wavelength radars for cloud microphysical research was investigated in experiments at the Elk Mountain Observatory near Laramie, Wyoming, between April 1990 and March 1992. The 95-GHz polarimetric ...
Evaluation of COAMPS Forecasts of Coastal Stratus Using Satellite Microphysical Retrievals and Aircraft Measurements
Publisher: American Meteorological Society
Abstract: A field project was carried out offshore of central Oregon during August 1999 to evaluate mesoscale model simulations of coastal stratiform cloud layers. Procedures for mapping cloud physical parameters such as cloud optical ...
