Raindrop Distributions at Franklin, North Carolina
Author: Eugene Albert Mueller
Publisher:
ISBN:
Category : Rain and rainfall
Languages : en
Pages : 180
Book Description
Raindrop size distributions are presented in a tabular form for 4721 samples of one cubic meter each. These were obtained from a drop camera near Franklin, North Carolina during the period of December 21, 1960 through March 25, 1962. For each of the samples, certain parameters calculated from the distribution are reported. These include rainfall rate, radar reflectivity, liquid water content, attenuation cross-section, median volume diameter, and the total number of drops. Average distributions for various rainfall rates and radar reflectivities are also reported. (Author).

Propagation of Millimeter Waves Through Rainfall

Languages : en
Pages : 0
Book Description
A study on rainfall attenuation at 11 and 36GHz and on prediction of rain-attenuation statistics at 11, 20 and 36 GHz from point rainfall measurements is presented. Emphasis is given on the effects of raindrop size distribution and the application of a "synthetic storm" model, respectively. A "generalised gamma" distribution introduced by Deirmendjian is used for evaluating the ratio of 36.5GHz to 11 GHz attenuation, as a function of the variance of the distribution and some of the theoretical values are compared with those predicted by known drop-size distributions. Attenuation measurements simultaneously recorded at 11 and 36.SGHz (Bradford link) are compared with Laws and Parsons' drop-size distribution and are included between theoretical boundaries obtained from "generalised gamma" distribution. It is shown from this dual frequency experiment that Laws and Parsons' distribution represents on average the rain at moderate attenuations whereas at low attenuation values the actual rain consists of drops smaller than those accounted for by Laws and Parsons. Six months' statistics of rain-attenuation at 11 and 36.5GHz demonstrate that the expected traction of raining time that attenuation exceeds a specified value follow a log-normal distribution. Attenuation statistics measured from the 13.6km Bradford link at 11 and 36.5GHz are found to be in good agreement with statistics predicted from a technique based on a "synthetic storm" model. Attenuation predictions for a number of in-line partially overlapping links in East Anglia indicate the application of this technique in storms of arbitrary orientation and in short and intermediate path lengths. For relatively short links, good estimates of attenuation/time profiles, for individual events, are obtained whereas improved event correlations can be seen on longer links in case of storms moving almost parallel to the link. It is also shown that the use of individual storm velocities is not more advantageous (in terms of prediction accuracy) than the use of an average storm velocity.

Polarimetric Doppler Weather Radar
Author: V. N. Bringi
Publisher: Cambridge University Press
ISBN: 9780521623841
Category : Science
Languages : en
Pages : 666
Book Description
This 2001 book provides a detailed introduction to the principles of Doppler and polarimetric radar, focusing in particular on their use in the analysis of weather systems. The design features and operation of practical radar systems are highlighted throughout the book in order to illustrate important theoretical foundations. The authors begin by discussing background topics such as electromagnetic scattering, polarization, and wave propagation. They then deal in detail with the engineering aspects of pulsed Doppler polarimetric radar, including the relevant signal theory, spectral estimation techniques, and noise considerations. They close by examining a range of key applications in meteorology and remote sensing. The book will be of great use to graduate students of electrical engineering and atmospheric science as well as to practitioners involved in the applications of polarimetric radar systems.
