Concerning the Limiting Behavior of Time-dependent Slope Winds
Publisher: American Meteorological Society
Abstract: Some controversy has developed concerning the results of analytical katabatic-flow models, which appear to show that slope flows become infinite for zero slope angles and adiabatic lapse rates. It is shown that in the ...
Diurnal Boundary-Layer Development over Sloping Terrain
Publisher: American Meteorological Society
Abstract: A one-dimensional prognostic model of the atmospheric boundary layer coupled to a surface energy budget is described which utilizes a profile formulation (non-local) for exchange coefficients in the daytime convective ...
Specification of the Scale and Magnitude of Thermals Used to Initiate Convection in Cloud Models
Publisher: American Meteorological Society
Abstract: Boundary layer similarity techniques are employed to specify the scale and intensity of a thermal perturbation used to initialize a cloud in a numerical cloud model. Techniques are outlined to specify the needed similarity ...
Time Series Construction of Summer Surface Temperatures for Alabama, 1883–2014, and Comparisons with Tropospheric Temperature and Climate Model Simulations
Publisher: American Meteorological Society
Abstract: hree time series of average summer [June?August (JJA)] daily maximum temperature (TMax) are developed for three interior regions of Alabama from stations with varying periods of record and unknown inhomogeneities. The time ...
A Multi-Layer Transient Model of Coastal Upwelling
Publisher: American Meteorological Society
Abstract: The transient development of wind-driven coastal upwelling in a rotating, stratified ocean is simulated using a four-layer numerical model. All longshore derivatives in the velocity field are neglected as are mixing processes ...
Surface Temperature Variations in East Africa and Possible Causes
Publisher: American Meteorological Society
Abstract: Surface temperatures have been observed in East Africa for more than 100 yr, but heretofore have not been subject to a rigorous climate analysis. To pursue this goal monthly averages of maximum (TMax), minimum (TMin), and ...
Reducing Noise in the MSU Daily Lower-Tropospheric Global Temperature Dataset
Publisher: American Meteorological Society
Abstract: The daily global-mean values of the lower-tropospheric temperature determined from microwave emissions measured by satellites are examined in terms of their signal, noise, and signal-to-noise ratio. Daily and 30-day average ...
Predictability of the Stable Atmospheric Boundary Layer
Publisher: American Meteorological Society
Abstract: The partial differential equation set for the horizontally homogeneous nocturnal boundary layer under first-order closure is discretized and truncated to a two-layer system. This system can be treated as a coupled four-layer ...
The Use of a Mesoscale Numerical Model for Evaluations of Pollutant Transport and Diffusion in Coastal Regions and over Irregular Terrain
Publisher: American Meteorological Society
Abstract: A modelling approach is presented that appears to have the potential to provide reliable assessments of pollution concentration in coastal zones and complex terrain, where the assumptions behind current operational air ...
