Download or read book Radar Detection of Turbulence in Thunderstorms written by Alan R. Bohne and published by . This book was released on 1981 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theoretical investigations are undertaken to relate intensity of turbulent air motion to Doppler radar spectrum mean and variance in precipitation environments. Examples of theoretical radar derived turbulence power density spectra and total precipitation motion variance show that effects due to imperfect particle response are significant for turbulence scale lengths less than 250 m. Doppler spectrum variance and estimated eddy dissipation rate (epsilon) are found strongly dependent upon precipitation environment for ranges less than about 20 km, and for cases where the turbulence outer scale length (lambda) is less than 0.5 km. They are also found to be essentially independent of lambda when the maximum pulse volume dimension is less than 1/2 lambda, and independent of range but strongly dependent on lambda at ranges where the maximum pulse volume dimension is greater than lambda. Estimation of epsilon by radar is shown to be unreliable until a method of remotely determining lambda is found. Nevertheless, classification of turbulence severity (index = cube root of epsilon is possible with only a reasonable guess of lambda. Analyses of aircraft/gust velocity data indicate that thunderstorm turbulence is localized into discrete patches, and that such localization must be accounted for when aircraft gust velocity data undergo power spectrum analysis.

This book was released on 1962 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: A penetrative flight by a T-33 aircraft was made through a large thunderstorm on 26 July 1960 over northern Arizona. From instruments recording airpla e accel r io, gl of t ck pitc a gle, preci e measure (! f / c) yielded a ver ical velocity every 60 ft of flight path. Calculated velocities differed from the true motions by a constant of integration. Evaluating the constant by alternate procedures produced two velocity distributions, differing from each other by a consta t.
