The Distribution of C2n as Measured by 50-, 405-, and 915-MHz Wind Profilers
Publisher: American Meteorological Society
Abstract: The distribution of backscattered power was computed for three wind profilers in the Colorado network that operated at 50,405, and 915 MHz. Since the backscattered power is a function of fluctuations in the refractivity ...
On the Nonlinear Theory for Gravity Waves on the Ocean's Surface. Part I: Derivations
Publisher: American Meteorological Society
Abstract: A general hydrodynamic solution is derived for arbitrary gravity-wave fields on the ocean surface by extending Stokes' (1847) original perturbational analysis. The solution to the nonlinear equations of motion is made ...
On the Nonlinear Theory for Gravity Waves on the Ocean's Surface. Part II: Interpretation and Applications
Publisher: American Meteorological Society
Abstract: In a previous paper (Weber and Barrick, 1977), a generalization of Stokes? perturbational technique permitted us to obtain solutions to higher orders for gravity-wave parameters for an arbitrary, two-dimensional periodic ...
The Accuracy of Divergence Estimates Calculated Using the Linear Vector Point Function Method and Three Profilers
Publisher: American Meteorological Society
Abstract: The effects of spatial, combined spatial and temporal sampling errors, and wind measurement errors on profiler-derived divergence estimates computed using the linear vector point function method are examined. Analysis ...
Effects of Small-Scale Vertical Motion on Radar Measurements of Wind and Temperature Profiles
Publisher: American Meteorological Society
Abstract: Vertical velocities were observed during the month of June 1990 with two side-by-side wind profilers at Platteville, Colorado. Many of the observations reveal strong wave motion, probably mountain lee waves, that sometimes ...
The Altitude Coverage of the Colorado Wind Profilers at 50, 405 and 915 MHz
Publisher: American Meteorological Society
Abstract: The maximum height performance of the 50, 405 nd 915 MHz Colorado wind profiles is computed from the wind profiler database. Results show that even though the 50 MHz profiler has the largest seasonal variation in the maximum ...
Quality Controls for Profiler Measurements of Winds and RASS Temperatures
Publisher: American Meteorological Society
Abstract: A new method for estimating winds and radio acoustic sounding system temperatures from radar Doppler measurements for the new NOAA wind profilers is described. This method emphasizes the quality of 6-min measurements prior ...
The Variations of Cn2 Between 4 and 18 km above Sea Level as Measured over 5 Years
Publisher: American Meteorological Society
Abstract: We computed the monthly average backscattered power over a five-year period for the Fleming 50 MHz wind profiler, which is proportional to CN2. We found that in addition to seasonal cycle in CN2 below the tropopause, there ...
Effects of Precipitation on UHF Wind Profiler Measurements
Publisher: American Meteorological Society
Abstract: Horizontal winds in the presence of precipitation were measured routinely with a UHF (405 MHz) Wind Profiler. The profiler had five beam-pointing positions so independent measurements of horizontal winds could be compared ...
The Precision and Relative Accuracy of Profiler Wind Measurements
Publisher: American Meteorological Society
Abstract: Two independent wind profiles were measured every hour during February 1986 with a five-beam, UHF (405 MHz) wind Profiler at Platteville, Colorado. Our analysis of the horizontal wind components over all heights for the ...
