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.

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

Book Synopsis Developing Techniques for Automated Forecasting of Clear Air Turbulence by : Frank Lewis
Download or read book Developing Techniques for Automated Forecasting of Clear Air Turbulence written by Frank Lewis and published by . This book was released on 1971 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work reported is directed toward adapting the scheme developed by the Stanford Research Institute for automated forecasting of Clear Air Turbulence (CAT). An important element of the scheme is the relation of CAT OCCURRENCE TO METEOROLOGICAL PARAMETERS. Multi-dimensional contingency tables are developed for specifying the probability of occurrence of CAT from values of meteorological parameters. The table generating procedure will require modification to solve the problem of the sparcity of data which occurs in some of the cells of the tables. Nevertheless, the reductions of variance obtained with the developmental set of data suggest that multi-dimensional contingency tables may produce effective specification of the probability of CAT from meteorological parameters in an automated system.

Book Synopsis Forecasting Clear-air Turbulence by Computer Techniques by : Roy M. Endlich
Download or read book Forecasting Clear-air Turbulence by Computer Techniques written by Roy M. Endlich and published by . This book was released on 1967 with total page 92 pages. 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).
