Rapid Temporal Changes of Boundary Layer Winds
Publisher: American Meteorological Society
Abstract: The statistical distribution of the magnitude of the vector wind change over 0.25-, 0.5-, 1-, and 2-h periods based on central Florida data from November 1999 through August 2001 is presented. The distributions of the 2-h ...
The Coherence Time of Midtropospheric Wind Features as a Function of Vertical Scale from 300 m to 2 km
Publisher: American Meteorological Society
Abstract: The coherence between vertical wind profiles separated by a time lag is measured as a function of vertical scale from Doppler radar wind profiler data. Each profile covers altitudes from 6811 m to 16?261 m and is Fourier ...
The Scales of Variation of Turbulent Kinetic Energy Dissipation in Hurricanes
Publisher: American Meteorological Society
Abstract: Conventional techniques for determining which features of hurricanes govern their distribution of kinetic energy dissipation rate (?) fail to yield significant correlations because of the high random variability of ?. ...
On the Size Distribution of Raindrops in Hurricane Ginger
Publisher: American Meteorological Society
Abstract: Airborne foil impactor measurements in Atlantic Hurricane Ginger (1971) show a raindrop size spectrum which is well represented by an exponential relation of the Marshall-Palmer type. No difference was observed between the ...
The Turbulent Microstructure of Hurricane Caroline (1975)
Publisher: American Meteorological Society
Abstract: Microscale horizontal velocity fluctuation measurements in Hurricane Caroline (1975) show that except in the eye, turbulent energy dissipation does not vary systematically with wind speed or altitude. Inertial subrange-shaped ...
Airborne Hot-Film Measurements of the Small-Scale Structure of Atmospheric Turbulence During GATE
Publisher: American Meteorological Society
Abstract: Fluctuations of temperature, horizontal velocity and vertical velocity were measured at scales from 50 m to 5 cm with airborne hot-film anemometers at altitudes of 150 and 900 m in clear air, and in subcloud air with and ...
Measuring Atmospheric Turbulence with Airborne Hot-Film Anemometers
Publisher: American Meteorological Society
Abstract: Extensive flight tests during GATE showed hot-film anemometry to be a useful tool for the airborne measurement of atmospheric turbulence in clear air and in subcloud rain, but not within clouds. Root-mean-square noise ...
