Errors in Radio Acoustic Sounding of Temperature
Publisher: American Meteorological Society
Abstract: With the use of simultaneous correction for radial wind, the accuracy of radio acoustic sounding systems for the measurement of temperature has been substantially improved. The temperature accuracy can now be affected by ...
UHF Wind Profilers: A New Tool for Diagnosing Tropical Convective Cloud Systems
Publisher: American Meteorological Society
Abstract: Uncertainty in the magnitude and distribution of diabatic heating associated with precipitating cloud systems is one of the major factors giving rise to uncertainty in the simulation of large-scale atmospheric circulations ...
VHF Echoes from the High-Latitude Mesosphere and Lower Thermosphere: Observations and Interpretations
Publisher: American Meteorological Society
Abstract: Recently published data (Ecklund and Balsley) describing VHF radar echo characteristics from the Arctic mesosphere and lower thermosphere show a remarkable seasonal dependence of both the echo height and echo intensity: ...
A UHF Wind Profiler for the Boundary Layer: Brief Description and Initial Results
Publisher: American Meteorological Society
Abstract: In this paper we describe a boundary layer radar recently developed at NOAA's Aeronomy Laboratory. This radar extends wind profiler technology by using a small, relatively inexpensive radar to provide continuous, high-resolution ...
Direct Measurement of Large‐Scale Vertical Velocities Using Clear‐Air Doppler Radars
Publisher: American Meteorological Society
Abstract: Radars that can make wind measurements in the clear air are expected to play an increasing role in meteorological observing systems in the future, especially for horizontal wind measurements. This paper considers the ...
Average Vertical Motions in the Tropical Atmosphere Observed by a Radar Wind Profiler on Pohnpei (7°N Latitude, 157°E Longitude)
Publisher: American Meteorological Society
Abstract: Average vertical profiles of the vertical wind obtained under clear sky conditions as weal as under conditions of both light-to-moderate and heavy rainfall am presented from data obtained using a radar wind profiler located ...
Objective Tropopause Height Determination Using Use-Resolution VHF Radar Observations
Publisher: American Meteorological Society
Abstract: The magnitude of backscattered power observed at vertical incidence by a VHF radar is related to atmospheric stability in accordance with the Fresnel scattering model. Utilizing a modified Fresnel scattering model, we can ...
Sea Surface Currents in the Equatorial Pacific from VHF Radar Backscatter Observations
Publisher: American Meteorological Society
Abstract: We present the analysis of three months of continuous sea-surface current data obtained by a VHF wind profiling radar at Christmas Island in the central equatorial Pacific. These results, which were obtained during the ...
Research Applications of a Boundary-Layer Wind Profiler
Publisher: American Meteorological Society
Abstract: A small UHF radar wind profiler was operated over a 40-day period during the summer of 1990 at a site on the windward coast of the island of Hawaii. It provided continuous measurements of winds up to the height of the ...
On the Potential of VHF Wind Profilers for Studying Convective Processes in the Tropics
Publisher: American Meteorological Society
Abstract: In this paper we provide a set of examples to demonstrate the potential of VHF radar wind profilers for studying tropical convection processes. Our examples were extracted from data obtained from the NOAA/CU Pacific Profiler ...
