Continuous Observations of Humidity Profiles with the MU Radar–RASS Combined with GPS and Radiosonde Measurements
Publisher: American Meteorological Society
Abstract: In this paper a radar remote-sensing technique of a humidity profile by Tsuda et al. is improved so as to determine continuous time?height variations of humidity. The volume reflectivity (?) and turbulence energy dissipation ...
MST Radar Observations of a Saturated Gravity Wave Spectrum
Publisher: American Meteorological Society
Abstract: We present vertical wavenumber spectra of mesoscale wind fluctuations using data observed in the troposphere, lower stratosphere and mesosphere by the MU radar at 35°N in Japan in October 1986 and June 1987, as well as ...
A Comparison of VHF Radar Vertical-Velocity Measurements by a Direct Vertical-Beam Method and by a VAD Technique
Publisher: American Meteorological Society
Abstract: Vertical-velocity measurements made by a direct vertical-beam method are compared to vertical velocities derived from VAD (velocity-azimuth display) measurements over a 27-h period. The results indicate that the two types ...
Sea-Breeze Circulation over Jakarta, Indonesia: A Climatology Based on Boundary Layer Radar Observations
Publisher: American Meteorological Society
Abstract: Characteristics of sea-breeze circulation over the tropical site of Jakarta, Indonesia, have been documented based on analyses of satellite images and data from long-term L-band boundary layer radar measurements carried ...
Observations of a Reversal in Long-Term Average Vertical Velocities near the Jet Stream Wind Maximum
Publisher: American Meteorological Society
Abstract: Analysis of vertical velocity measurements made for four days each month over the period from 1986 to 1988 by the MU radar in Japan shows a reversal in direction near the peak in the zonal wind profile during the winter ...
Studies of Velocity Fluctuations in the Lower Atmosphere Using the MU Radar. Part I: Azimuthal Anisotropy
Publisher: American Meteorological Society
Abstract: We present in this paper a study of the azimuthal anisotropy of the motion field observed during a six-day campaign in March 1986 using the MU radar in Shigaraki, Japan. The radial wind velocity was observed at 20° zenith ...
An Analysis Technique for Deriving Vector Winds and In-Beam Incidence Angles from Radar Interferometer Measurements
Publisher: American Meteorological Society
Abstract: We present a method for deriving horizontal velocities, vertical velocities, and in-beam incidence angles from radar interferometer data. All parameters are calculated from the slope and intercept of straight lines fitted ...
HRDI Observations of Mean Meridional Winds at Solstice
Publisher: American Meteorological Society
Abstract: High Resolution Doppler Imager (HRDI) measurements of daytime and nighttime winds at 95 km are used to deduce seasonally averaged Eulerian mean meridional winds during six solstice periods. These estimates are compared ...
