Ultrafine Particles in the Lower Troposphere: Major Sources, Invisible Plumes, and Meteorological Transport Processes
Publisher: American Meteorological Society
Abstract: AbstractUltrafine particles (UFPs) are distributed highly unevenly in the lower troposphere. Although these UFPs are positively detectable and have been studied for more than a century, their three-dimensional distribution, ...
The Vertical Distribution of Radon in Clear and Cloudy Daytime Terrestrial Boundary Layers
Publisher: American Meteorological Society
Abstract: Radon (222Rn) is a powerful natural tracer of mixing and exchange processes in the atmospheric boundary layer. The authors present and discuss the main features of a unique dataset of 50 high-resolution vertical radon ...
Cliff–Ramp Patterns and Kelvin–Helmholtz Billows in Stably Stratified Shear Flow in the Upper Troposphere: Analysis of Aircraft Measurements
Publisher: American Meteorological Society
Abstract: Cliff?ramp patterns (CR) are a common feature of scalar turbulence, characterized by a sharp temperature increase (cliff) followed by a more gradual temperature decrease (ramp). Aircraft measurements obtained from NOAA ...
Velocity and Temperature Structure Functions in the Upper Troposphere and Lower Stratosphere from High-Resolution Aircraft Measurements
Publisher: American Meteorological Society
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 ...
Modification of the Atmospheric Boundary Layer by a Small Island: Observations from Nauru
Publisher: American Meteorological Society
Abstract: Nauru, a small island in the tropical Pacific, generates cloud plumes that may grow to over 100-km lengths. This study uses observations to examine the mesoscale disturbance of the marine atmospheric boundary layer by the ...
Low-Level Convergence Lines over Northeastern Australia. Part I: The North Australian Cloud Line
Publisher: American Meteorological Society
Abstract: Observations of dry-season north Australian cloud lines (NACLs) that form in the Gulf of Carpentaria region of northern Australia and the sea-breeze circulations that initiate them are described. The observations were made ...
SPECIAL—Savanna Patterns of Energy and Carbon Integrated across the Landscape
Publisher: American Meteorological Society
Abstract: are highly significant global ecosystems that consist of a mix of trees and grasses and that are highly spatially varied in their physical structure, species composition, and physiological function (i.e., leaf area and ...
