Abstract: Most simulations of bulk valley-drainage flows depend heavily on parameterizations. The 1984 Atmospheric Studies in Complex Terrain (ASCOT) field experiment in Brush Creek Valley, Colorado, provided an unprecedented density ...

Abstract: ata from six urban areas in a nationwide network of sites within the surface roughness layer are examined. It is found that the average velocity variances in time, derived by averaging the conventional variances from a ...

Abstract: High-resolution measurements obtained from NOAA ?best? atmospheric turbulence (BAT) probes mounted on an EGRETT high-altitude research aircraft were used to characterize turbulence in the upper troposphere and lower ...

Abstract: Turbulence and air-surface exchange are important factors throughout the life cycle of a tropical cyclone. Conventional turbulence instruments are not designed to function in the extreme environment encountered in such ...

Abstract: Fluxes and flux-divergences of mass and momentum in Brush Creek Valley, computed from measurements taken by Tethersondes and Doppler sodars in the 1984 ASCOT experiment, are presented. Estimates of mass influx from open ...

Abstract: he utility of aggregating data from near-surface meteorological networks for initiating dispersion models is examined by using data from the ?WeatherBug? network that is operated by Earth Networks, Inc. WeatherBug instruments ...

Abstract: mall environmental research aircraft (ERA) are becoming more common for detailed studies of air?surface interactions. The Sky Arrow 650 ERA, used by multiple groups, is designed to minimize the complexity of high-precision ...
