Turbulence Length Scales in Stably Stratified Free Shear Flow Analyzed from Slant Aircraft Profiles
Publisher: American Meteorological Society
Abstract: The vertical turbulence structure in the marine atmosphere close to a coastline is investigated using airborne measurements. The measurements are from a field experiment close to the coast in the southeast of Sweden, in ...
Simulated Liquid Water and Visibility in Stratiform Boundary-Layer Clouds over Sloping Terrain
Publisher: American Meteorological Society
Abstract: The amount of liquid water in stratus clouds or fog is discussed from the point of view of estimating visibility variations in areas with complex terrain. The average vertical profile of liquid water from numerical simulations ...
Is There a Diurnal Cycle in the Summer Cloud-Capped Arctic Boundary Layer?
Publisher: American Meteorological Society
Abstract: Data from the Arctic Ocean Experiment 2001 (AOE-2001) are used to study the vertical structure and diurnal cycle of the summertime central Arctic cloud-capped boundary layer. Mean conditions show a shallow stratocumulus-capped ...
Modeling the Impact of Marine Stratocumulus on Boundary Layer Structure
Publisher: American Meteorological Society
Abstract: An ensemble-average closure model intended for mesoscale studies is applied to a marine stratocumulus-capped PBL. The intention is to test this model, in particular, for cases where cloud and subcloud layers are decoupled. ...
Simulations of Supercritical Flow around Points and Capes in a Coastal Atmosphere
Publisher: American Meteorological Society
Abstract: Fully 3D nonlinear model simulations for supercritical flow along locations at the California coast, at Cape Mendocino, and Point Sur, are presented. The model results are objectively and subjectively verified against ...
Estimating the Effects on the Regional Precipitation Climate in a Semiarid Region Caused by an Artificial Lake Using a Mesoscale Model
Publisher: American Meteorological Society
Abstract: The effects on the regional precipitation climate by the construction of an artificial lake, in a semiarid region are studied. The study is performed using a mesoscale model to identify the larger-scale meteorological ...
Diurnal Cycle of Supercritical Along-Coast Flows
Publisher: American Meteorological Society
Abstract: In this study, a three-dimensional hydrostatic mesoscale model is used to address the transient behavior of supercritical along-coast flow. A control experiment and several sensitivity tests are performed in order to ...
The Effect of Inertial Navigation System Time Response on Airborne Turbulence Measurements
Publisher: American Meteorological Society
Abstract: Wind calculations from a radome gust probe system, in combination with a wander-angle Inertial Navigation System (INS), are used to calculate turbulence (variance and fluxes) by eddy correlation. The difference in time ...
Turbulence Structure in Decoupled Marine Stratocumulus: A Case Study from the ASTEX Field Experiment
Publisher: American Meteorological Society
Abstract: The average and turbulence structure of two marine stratocumulus layers, from the Atlantic Stratocumulus Transition Experiment, are analyzed. These layers ware in adjacent air masses with different histories: one cloud ...
Analysis of a Radome Air-Motion System on a Twin-Jet Aircraft for Boundary-Layer Research
Publisher: American Meteorological Society
Abstract: A ?radome gust probe? system was installed on a twin-jet aircraft for the purpose of boundary-layer research. This system provided a useful relatively low-cost method for air motion and turbulence measurements on an aircraft ...
