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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
