Evidence far a k−5/3 Law Inertial Range in Mesoscale Two-Dimensional Turbulence
Publisher: American Meteorological Society
Abstract: The observational evidence for k?5/3 law behavior in the atmospheric kinetic energy spectrum is reviewed. This evidence includes the results of atmospheric wind variability studies and the observed scale dependence of ...
Theoretical Interpretation of Atmospheric Wavenumber Spectra of Wind and Temperature Observed by Commercial Aircraft During GASP
Publisher: American Meteorological Society
Abstract: This paper contains a theoretical interpretation of the wavenumber spectra of wind and temperature obtained from an analysis of data from over 6900 flights during the Global Atmospheric Sampling Program. The spectra cover ...
On the Use of Radars for Operational Wind Profiling
Publisher: American Meteorological Society
Abstract: The application of clear-air radars to operational wind profiling is considered. Several alternative techniques for determining atmospheric winds from radars are surveyed and, in light of the current interest in operational ...
An Objective Method for the Determination of Tropopause Height from VHF Radar Observations
Publisher: American Meteorological Society
Abstract: The relationship between the magnitude of backscattered power observed at vertical incidence by a VHF radar is related to atmospheric stability in accordance with the recently developed Fresnel scattering model. Utilizing ...
A Technique for Determining the Temperature Profile from VHF Radar Observations
Publisher: American Meteorological Society
Abstract: A technique is presented which enables an estimate of the atmospheric temperature profile from atmospheric stability measurements made by vertically looking VHF radars. The determination of the tropopause height leads to ...
A Brief Climatology of Vertical Wind Variability in the Troposphere and Stratosphere as Seen by the Poker Flat, Alaska, MST Radar
Publisher: American Meteorological Society
Abstract: A statistical analysis of vertical air motion has been performed for data taken in the 3-20 km altitude range by the Poker Flat MST radar during the period September 1979-January 1982. The variability of vertical velocities ...
Doppler Radar Probing of the Clear Atmosphere
Publisher: American Meteorological Society
Abstract: In the past few years, sensitive Doppler radars have been used to probe the clear atmosphere from the boundary layer up to stratospheric altitudes. Routine Doppler radar observations are now attainable over a wide range ...
Relationship of Precipitation to Vertical Motion Observed Directly by a VHF Wind Profiler During a Spring Upslope Storm Near Denver, Colorado
Publisher: American Meteorological Society
Abstract: A comparison is presented between vertical motion observed directly by a VHF wind profiler and the rainfall rate measured at two surface stations during an intense Colorado upslope spring storm. Averaged (8?9 hrs) precipitation ...
A Climatology of Atmospheric Wavenumber Spectra of Wind and Temperature Observed by Commercial Aircraft
Publisher: American Meteorological Society
Abstract: Atmospheric wavenumber spectra of wind and temperature have been obtained from over 6000 commercial aircraft flights made during the Global Atmospheric Sampling Program. Temperature and velocity spectra are approximately ...
Mesoscale Variability of Jet Stream Winds Observed by the Sunset VHF Doppler Radar
Publisher: American Meteorological Society
Abstract: Sensitive Doppler radars have recently been developed that can routinely observe wind in the free atmosphere up to stratospheric heights. One of these, the 40 MHz Sunset radar, was used to observe the three-dimensional ...
