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.

Download or read book Air Turbulence and its Methods of Detection written by Leonardo Di G. Sigalotti and published by CRC Press. This book was released on 2023-02-24 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is a concise guide dealing with the subject of air turbulence and its methods of detection with particular applications to aviation turbulence. It begins with a general description of turbulence and provides a background into the nature and causes of atmospheric turbulence that affect aircraft motion, giving updates on the state-of-the-art research on clear air turbulence (CAT). Important physical processes leading to the Kelvin-Helmholtz instability, a primary producer of CAT, are also explained. The several categories of CAT along with its impact on commercial aviation are also presented in a separate chapter, with particular emphasis on the structural damages to planes and injuries. The central theme of the book deals with both the earlier and the latest CAT detecting methods and techniques for remote and in situ sensing and forecasting. A concise presentation of new technologies for reducing aviation weather-related accidents is also offered. A chapter on the weather accident prevention project of the NASA aviation safety program is also included. Additionally, the book ends with a full description of the recent research activities on CAT and future challenges in turbulence detection, prediction and avoidance.
Download or read book Doppler Radar and Weather Observations written by Richard J. Doviak and published by Elsevier. This book was released on 2012-12-02 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doppler Radar and Weather Observations deals with the use of Doppler radar to make observations of a variety of weather phenomena such as tornado vortices, hurricanes, and lightning channels. Topics covered include electromagnetic waves and propagation; weather echo signals; Doppler spectra of weather echoes; and meteorological radar signal processing. Rain and turbulence measurements are also considered, along with observations of winds, storms, and related phenomena. Comprised of 11 chapters, this book begins with an introduction to weather radar principles and how the radar parameters and signal characteristics relate to the target's meteorological properties. The effect of the atmosphere on the path of the signal is then examined, together with techniques used in extracting a target's properties from its echoes. The radar signal path from the transmitter, through the antenna, along the beam to the target, and on its return to the receiver is also discussed. Subsequent chapters explore the discrete Fourier transform and its application to weather echo signals; the weather Doppler spectrum and the signal processing methods used to derive its principal moments; range and Doppler velocity ambiguities as they pertain to distributed targets; and the limitations imposed by antenna sidelobes, ground clutter, signal decorrelation, and power. A comprehensive treatment of pulse compression and the Doppler processing of frequency modulated signals is given. This monograph should be of value to oceanographers, meteorologists, atmospheric scientists, and radar engineers, as well as students and researchers interested in Doppler radar principles.
