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.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Pilot reports of clear-air turbulence from four special five-day reporting periods are used to investigate relationships between turbulence probability and meteorological factors. The meteorological analyses are made by computer on a 2.5 degrees latitude/longitude grid, on the basis of standard upper-air observations. Analyses are made for the United States for altitude layers 50 mb (approximately 4000 ft) thick. Temperature analyses interpreted as thermal wind shear are used to compensate for wind observations missing in high-speed portions of the flow. The best meteorological indicators of turbulence are those related to the wind field. These indicators are vertical vector wind shear, deformation, and divergence. The analysis for turbulence is made from meteorological factors and pilot reports in terms of the probability of encountering significant turbulence (greater than light intensity) during flight segments 100 nautical miles long. Numerical forecasts of upper winds are prepared for the turbulence-reporting periods on the basis of advection and geostrophic departures. The departures are evaluated directly from the wind analyses by use of the balance equation. The advection uses upstream space differences and is tested in both explicit and implicit forms. (Author).

Book excerpt: This technical note is a compilation of the latest clear air turbulence(CAT) forecasting techniques used by AFGWC forecasters. It is a comprehensive treatment of a complex and unique forecasting subject. The methods are relatively easy to follow and are a step-by-step approach to forecasting this weather phenomenon. This document replaces AFGWC Tech Memo 70-7 Turbulence Forecasting Procedures, 15 Dec 1970. Over the past 15 years the automated CAT routines have been totally replaced. Also, synoptic rules of thumb and model relationships are now better understood and documented.

Available in PDF, EPUB and Kindle. Book excerpt: Clear-air turbulence (CAT) prediction is vitally important to military aviation and the successful completion of Department of Defense (DoD) operations such as air to air refueling and new national defensive weapon systems such as directed energy platforms. The unique mission requirements of military aircraft often require strict avoidance of turbulent regions. Traditionally, weather forecasters have found it difficult to accurately predict CAT. In order to forecast regions where CAT might occur, forecasters must first determine the location of breaking waves caused by either Kelvin-Helmholtz instabilities or topographically forced internal gravity waves (mountain waves) in the atmosphere. The United States Air Force (USAF) 15th Operational Weather Squadron (15th OWS) requested an updated method of predicting CAT and this request was ranked as one of the highest priority research needs by the HQ USAF Director of Weather, Deputy Chief of Staff for Air and Space Operations. A new method of forecasting turbulence was developed in this work and the operational model was delivered to the 15th OWS for immediate inclusion into their operations. This method combines output from the Knapp-Ellrod index and the Naval Research Laboratory s Mountain Wave Forecast Model (MWFM) onto a single chart. Displaying these tools together allows forecasters to view both causes of CAT simultaneously. Furthermore, a new visualization tool is developed that allows a forecaster to view several layers at the same time as well as a composite chart to greatly reduce the time required to produce turbulence charts by OWS forecasting centers worldwide. Tests of forecast accuracy, as determined by pilot reports (PIREPS), between charts currently produced by USAF OWSs and this new method were compared, with the new method producing far superior forecast results. This method revolutionizes

This book was released on 2012-12-06 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 22 (thesis year 1977) a total of 10,658 theses titles from 28 Canadian and 227 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 22 reports theses submitted in 1977, on occasion, certain universities do report theses submitted in previous years but not reported at the time.

Available in PDF, EPUB and Kindle. Book excerpt: Clear air turbulence data were collected from two of the four world-wide reporting periods set up by the International Civil Aviation Organization (ICAO). The occurrences and non-occurrences of turbulence were summarized with respect to time periods, altitudes, and geographical locations. These data were analyzed in relation to associated meteorological parameters and large-scale synoptic patterns. Special attention was given to areas with at least 25 percent probability of moderate or greater turbulence. Vertical wind shear appeared to be an important parameter along with 12-hour changes in wind speed, vertical wind shear, and horizontal wind shear. The synoptic patterns on the mean 300-mb charts and the individual 300-mb charts were discussed in relation to the probabilities of moderate or greater turbulence. The following forecast criteria were suggested: moderate or greater turbulence will be found (1) within 150 miles of a jet stream with at least a 100-knot maximum wind speed if the vertical wind shear is at least 4 knots per 1000 feet, or (2) within 150 miles of a sharp trough line with a marked horizontal wind shear across the trough line.
