Radar wind profiler observations of solar semidiurnal atmospheric tides
Semidiurnal solar tides in the mid-latitude troposphere are investigated using harmonic analysis of 404 MHz radar profiler wind data obtained from a wide longitude zone in the U.S. The tides are apparent above a 1000-m-deep surface layer and increase in amplitude with height, attaining speeds of 0.5-0.7 rn/s at 5-7 km. Observed wind characteristics agree well with tidal characteristics obtained...
متن کامل8.1 Development of a Climatology of Vertically Complete Wind Profiles from Doppler Radar Wind Profiler Systems
Space vehicle loads and trajectory assessments utilize archives of both discrete and sequential wind profiles to ensure robust structural integrity during vehicle design. Historically, vehicle programs have used balloonbased measurements, which have three primary limitations inherent to balloon systems. First, the high cost of balloon releases makes high-frequency balloon sampling impractical, ...

متن کاملA Comparison between Polarimetric Radar and Wind Profiler Observations of Precipitation in Tropical Showers
This paper describes the results of an experiment that combines the data from a 5-cm-wavelength polarimetric radar and multiple-frequency wind profilers to examine the polarimetric signatures associated with the microphysical structure of several relatively shallow thunderstorms and also to examine quantitative rainfall measurements made with the polarimetric radar. These shallow storms produce...
متن کاملCombined Wind Profiler/Polarimetric Radar Studies of the Vertical Motion and Microphysical Characteristics of Convection: Darwin and Oklahoma Observations
Wind profilers offer the unique ability to directly measure vertical motion profiles through precipitating and non-precipitating cloud systems. This ability has been exploited through a series of analyses of storms near Darwin, Northern Australia, which have focused on the statistical characteristics of the vertical motion within a large number of storms as well as case studies of squall lines ...
