Book excerpt: Using Cygnus A as the source, a multi-frequency study of both scintillation rate and index was made in 1961 and 1962. Using an 84 ft parabola, simultaneous observations were made at 63, 112, 225, 1200, and 2980 Mc/s with angles of elevation from 0 to 5 degrees. Tropospheric scintillation rates at 1200 and 2980 Mc/s increase as the angle of elevation increased; the mean scintillation rates rose from 1x00/min at 1 degree of elevation to 1x75/min at 3 degrees of elevation. Scintillation indices decreased with increasing angle of elevation at 1200 and 2980 Mc/s; fitting a curve of the slant range to the irregularities to the data points yielded a best fit in the 1-2 km height region. Ionospheric scintillations at 63 and 112 Mc/s showed a wavelength dependence less than lambda; a comparison of 112 and 225 Mc/s data showed a closer approximation to a first power dependence. The hypothesis advanced for poor correlation of theoretical wavelength dependence and data is that the ray path traverses the auroral region and strong scattering results. Zenith angle variation shows a dependence between z (sec i) to the 1/2 power, the near zone case and (sec i) to the 1/2 power, the far zone regime. Differences in indices for Cygnus rise and Cygnus set on the longer wavelengths are attributed to the difference in the magnetic dip angle of the set and the rise positions; higher indices were observed for Cygnus set in the direction of the magnetic declination of 16 degrees W.

This book was released on 1965 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cumulus cloud events of the Florida peninsula that were observed during a 19-day period of photoreconnaissance in August and September 1957 are described and illustrated. The associated meteorological and rainfall events are also described and the intercorrelations among the various observations are pointed out. The study findings revealed that the principal factors governing the cloud and rainfall situations of the different days were (1) the low-level advection of water vapor into the peninsula from the oceanic surroundings, (2) the wind transport, into the heated peninsula from the oceans during the daytime, of pre -existing cumulus populations containing appreciable liquid water, (3) the low-level convergence, and associated updraft motion, engendered by the synoptic situation and the peninsula sea breezes, and (4) the precipitable water content of the lower Florida air mass.
