RISDiagnostic Equations for the Stable Boundary Layer Height: Evaluation and Dimensional Analysis
Publisher: American Meteorological Society
Abstract: The performance of diagnostic equations for the stable boundary layer height h is evaluated with four observational datasets that represent a broad range of latitudes, land use, and surface roughness. In addition, large-eddy ...
The Cessation of Continuous Turbulence as Precursor of the Very Stable Nocturnal Boundary Layer
Publisher: American Meteorological Society
Abstract: he mechanism behind the collapse of turbulence in the evening as a precursor to the onset of the very stable boundary layer is investigated. To this end a cooled, pressure-driven flow is investigated by means of a local ...
Exploring Self-Correlation in Flux–Gradient Relationships for Stably Stratified Conditions
Publisher: American Meteorological Society
Abstract: In this paper, the degree of scatter in flux?gradient relationships for stably stratified conditions is analyzed. It is generally found that scatter in the dimensionless lapse rate ?h is larger than in the dimensionless ...
Modeling the Evolution of the Atmospheric Boundary Layer Coupled to the Land Surface for Three Contrasting Nights in CASES-99
Publisher: American Meteorological Society
Abstract: The modeling and prediction of the stable boundary layer over land is a persistent, problematic feature in weather, climate, and air quality topics. Here, the performance of a state-of-the-art single-column boundary layer ...
Exploring the Possible Role of Small-Scale Terrain Drag on Stable Boundary Layers over Land
Publisher: American Meteorological Society
Abstract: This paper addresses the possible role of unresolved terrain drag, relative to the turbulent drag on the development of the stable atmospheric boundary layer over land. Adding a first-order estimate for terrain drag to the ...
A Conceptual View on Inertial Oscillations and Nocturnal Low-Level Jets
Publisher: American Meteorological Society
Abstract: In the present work Blackadar?s concept of nocturnal inertial oscillations is extended. Blackadar?s concept describes frictionless inertial oscillations above the nocturnal inversion layer. The current work includes ...

Intermittent Turbulence and Oscillations in the Stable Boundary Layer over Land. Part I: A Bulk Model
Publisher: American Meteorological Society
Abstract: In the stable boundary layer (SBL) it is observed often that turbulence is not continuous in space and time. This discontinuous, intermittent turbulence causes alternations from the mean evolution of the stratified atmospheric ...
The Minimum Wind Speed for Sustainable Turbulence in the Nocturnal Boundary Layer
Publisher: American Meteorological Society
Abstract: he collapse of turbulence in the nocturnal boundary layer is studied by means of a simple bulk model that describes the basic physical interactions in the surface energy balance. It is shown that for a given mechanical ...
Intermittent Turbulence and Oscillations in the Stable Boundary Layer over Land. Part II: A System Dynamics Approach
Publisher: American Meteorological Society
Abstract: In the stable boundary layer it is often observed that turbulence is not continuous in space and time. This discontinuous, intermittent turbulence causes alterations from the mean evolution of the stratified atmospheric ...
