Abstract: An exceptional concentric halo display was observed in Boulder, Colorado, on 21 July 1986. As many as six halos were observed and photographed simultaneously between 1530 and 1945 UTC. Extensive photographic documentation ...

Abstract: The Experiment on Rapidly Intensifying Cyclones over the Atlantic was carried out over the western North Atlantic Ocean to provide temporally continuous comprehensive datasets from which to document the life cycle of ...

Abstract: The study presented here describes the interactions that occurred between an advancing Pacific cold front and shallow Gulf of Mexico and Arctic air masses situated east of the Rocky Mountains during the Verification of the ...

Abstract: Vertical wind shears measured by the Plattevilie, Colorado wind profiler were used in conjunction with the geostrophic thermal wind equation to retrieve the horizontal thermal gradients and associated advections for a case ...

Abstract: Scattering of sunlight or moonlight by cloud particles can generate colorful optical patterns that are both scientifically and aesthetically interesting. Photographs of corona rings and iridescence are presented to demonstrate ...

Abstract: The National 0ceanic and Atmospheric Administration (NOAA) Wave Propagation Laboratory (WPL) wind profilers and accompanying radio acoustic sounding system (RASS) temperature profilers in eastern Colorado jointly measure ...

Abstract: This study uses a unique combination of airborne and satellite observations to characterize narrow regions of strong horizontal water vapor flux associated with polar cold fronts that occurred over the eastern North Pacific ...

Abstract: Dropsonde observations are used to document the mean vertical profiles of kinematic and thermodynamic conditions in the pre-cold-frontal low-level-jet (LLJ) region of extratropical cyclones over the eastern Pacific Ocean. ...

Abstract: A strong elevated temperature inversion in a landfalling winter storm in northern California produced two simultaneous melting layers with associated radar bright bands. The storm was observed with scanning and profiling ...

Abstract: his study examines the impact of microphysics regime on the relationship between orographic forcing and orographic rain in the coastal mountains of Northern California using >4000 h of data from profiling Doppler radars, ...
