Book Description
A summary is made of the modern theories concerning eddies in a Cb zone. Data concerning the structure of the turbulent zones inside and in the vicinity of Cb clouds are given according to the materials of special flight studies, as are the energy spectra of the vertical turbulent gusts of wind inside, below, and above the Cb clouds. The statistical characteristics of the disturbed motion of an aircraft in turbulent zones linked with Cb clouds are investigated.

Book Description
Turbulence-the randomly disordered movement of volumes of air of widely varying size-is one of the characteristic features of atmospheric air flows; its investigation is essential for the solution of several theoretical and practical problems. Until recently, owing to experimental difficulties, research on turbu lence was confmed mainly to the lower half of the troposphere. Theoretical investigations have consequently been based on these data. The rapid development of high-altitude aviation and cases of aircraft encoun tering hazardous turbulence led to a sharp intensification of research on turbu lence in the atmosphere up to 10-12 km, and subsequently at greater altitudes. Such research was confined initially to the characterization of the frequency of occurrence of gusts of different speeds, their relation to altitude, geographical conditions, time of day and year, and so on. At the end of the fifties, when the required measuring equipment and experimental techniques had been developed, it became possible to investigate the complete statistical characteristics of turbu lence: the spectral densities of the velocity fluctuations of air flows, structure functions, etc. These data stimulated the further development of theory related to the specific conditions of the free atmosphere.

Book Description
This publication is a presentation of cloud meteorology as experienced by a seasoned Aviation Meteorologist. It contains a comprehensive discussion of Cloud Meteorology, presenting explanations of cloud formation, cloud types and cloud dynamics, the atmospheric forces internal and external to cloud existence. It discusses the earths atmospheric-chaotic-nature and its impact on clouds and cloud systems. Clouds are visual indicators of the atmospheres dynamics and related weather phenomena, and, to some extent, predictors of coming weather conditions. Clouds are beautiful icons of nature and at the same time, complicated creatures studied by meteorology. It is the authors purpose to present the subject in a fashion comprehensible to both practicing meteorologists, and also the weather-neophyte. This material requires no more than an avid interest in CLOUDS, and a grasp of the American language, to acquire much insight into the wonders of our cloud-form nuturing atmosphere.

Book Description
Anyone who has experienced turbulence in flight knows that it is usually not pleasant, and may wonder why this is so difficult to avoid. The book includes papers by various aviation turbulence researchers and provides background into the nature and causes of atmospheric turbulence that affect aircraft motion, and contains surveys of the latest techniques for remote and in situ sensing and forecasting of the turbulence phenomenon. It provides updates on the state-of-the-art research since earlier studies in the 1960s on clear-air turbulence, explains recent new understanding into turbulence generation by thunderstorms, and summarizes future challenges in turbulence prediction and avoidance.

Book Description
This memorandum presents results of a limited literature survey showing the atmosphere is typically in a turbulent state and contains vertical motions due to eddies having a wide range of size and intensity. The methods of power spectral analysis and their applications to atmospheric turbulence studies are outlined, and references provided, for possible use in implementing needed programs at test ranges and in development projects. These programs should include comprehensive studies of the environmental turbulence at test ranges, which should themselves be regarded as instruments possessing inherent physical characteristics which influence the tests being made.
