Abstract: A network of sodars was operated in the late summer and fall of 1993 to monitor the occurrence of nocturnal winds from a canyon in Colorado's Front Range near the Rocky Flats Plant and to determine the influence of those ...

Abstract: A numerical modeling study was conducted to examine the response of the atmospheric boundary layer to inhomogeneous surface fluxes. The study was used to extend the results obtained from a field experiment carried out in ...

Abstract: A southeasterly flow in the form of a low-level jet that enters the Mexico City basin through a mountain gap in the southeast corner of the basin developed consistently in the afternoons or early evenings during a four-week ...

Abstract: An analysis of regional drainage flows in the Pacific Northwest is presented using results from a network of surface observations and a series of simulations carried out with a nested mesoscale model. The flows, which occur ...

Abstract: Measurements from the Southern Great Plains Cloud and Radiation Testbed site, which is situated in Oklahoma and Kansas and extends over an area approximately 300 km ? 350 km in extent, are combined with results from a ...

Abstract: Modifications to the properties of the boundary layer arising from surface flux variations over an area of 105 km2 are simulated with a mesoscale model using realistic meteorology and distributions of surface fluxes. The ...

Abstract: Current approaches to parameterizations of sub-grid-scale variability in surface sensible heat fluxes in general circulation models normally neglect the associated variability in mixed-layer depths. Observations and a ...

Abstract: Measurements of the turbulence structure of nocturnal slope flow are used to test the hypothesis that slope flow turbulence in the region above the low-level wind maximum is decoupled from the surface and has a local ...

Abstract: Measured characteristics of gust amplitudes and times in the neutral surface boundary layer are presented. The probability of gust amplitudes exceeding a prescribed level is shown to decrease exponentially with amplitude, ...
