This book was released on 1985 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analyses of First GARP Global Experiment (FGGE) data have been used to study three cases of maritime extratropical cyclone development. It has been demonstrated that these FGGE analyses are consistent with the observations through synoptic comparisons and satellite interpretations. Quasi-Lagrangian diagnostic budgets of mass, vorticity, angular momentum and heat have been computed in pressure coordinates for observed and model-generated cyclones. The roles of jet streaks and small static stability in the lower troposphere during rapid development of maritime cyclones have been documented. Vertical circulation trends in the mass budget are consistent with the sea-level pressure evolution in each case. Inward transport of vorticity due to the jet streak coincides with the rapid development phase. Vorticity budgets of these maritime cyclones appear to be consistent with earlier studies of continental cyclones. To complement the observational studies, similar diagnostic studies hace been done for numerical simulations of maritime cyclogenesis under straight upper-level flow. These studies demonstrate that similar physical mechanisms are involved in the simulated storms as were found in the FGGE-based studies. Two sets of numerical model predictions from the FGGE analyses were examined for an explosively deepening cyclone over the western North Pacific Ocean. Both models predicted the most rapid deepening phase too early and resulted in too low sea-level pressures.

Download or read book Varying Structure and Intensity Change Characteristics of Four Western North Pacific Tropical Cyclones written by Cecilia A. Askue and published by . This book was released on 1984 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Observational case studies of four tropical cyclones (Ellis, Hope, Judy, and Roger) from birth to decay are made using a variety of data sources from the First GARP Global Experiment (FGGE) year (1979). Each of these cyclones had uniquely different characteristics. Two became supertyphoons, one only a weak typhoon, and one only a tropical storm with a strong outer circulation. Two recurved, and two did not recurve. Information was derived from a combination of European Centre for Medium Range Weather Forecasts (ECMWF) large scale objective analyses, Joint Typhoon Warning Center (JTWC) Guam manual analyses, National Climatic Center (NCC) analyses published by the National Oceanic and Atmospheric Administration (NOAA), United States Air Force (USAF) aircraft reconnaissance data, and U.S. Defense Meteorological Satellite Program (DMSP) military satellite imagery. The combination of these rich data sources allowed a quantitative description of both large and small scale features. Emphasis is placed on cyclone structure and intensity change. Quantitative assessments of the varying relationships between inner and outer radii wind parameters are made. Preliminary results show the importance of the large scale (radius greater than seven degrees) environment in determining cyclone genesis and the importance of upper tropospheric outflow patterns in determining cyclone inner-core intensity change.

Download or read book A Vast Machine written by Paul N. Edwards and published by MIT Press. This book was released on 2010-03-12 with total page 547 pages. Available in PDF, EPUB and Kindle. Book excerpt: The science behind global warming, and its history: how scientists learned to understand the atmosphere, to measure it, to trace its past, and to model its future. Global warming skeptics often fall back on the argument that the scientific case for global warming is all model predictions, nothing but simulation; they warn us that we need to wait for real data, “sound science.” In A Vast Machine Paul Edwards has news for these skeptics: without models, there are no data. Today, no collection of signals or observations—even from satellites, which can “see” the whole planet with a single instrument—becomes global in time and space without passing through a series of data models. Everything we know about the world's climate we know through models. Edwards offers an engaging and innovative history of how scientists learned to understand the atmosphere—to measure it, trace its past, and model its future.

Download or read book Extratropical Cyclones written by Chester Newton and published by Springer. This book was released on 2018-11-22 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is composed of 12 review papers invited for the Palmen Memorial Symposium on Extratropical Cyclones held in Helsinki, Finland, 29 August - 2 September 1988. To celebrate the 90th anniversary of the birth of Professor Erik Palmén, this symposium was organized to give a state-of-the-art picture of research on the structure and dynamics of extratropical cyclones, a topic which Palmén pioneered during the era of advances in aerological analysis. This symposium was organized by the Geophysical Society of Finland and the American Meteorological Society in cooperation with the Danish, Norwegian and Swedish Geophysical Societies. Extratropical Cyclones offers state-of-the-art information on extratropical cyclones, and recent findings by European and American authorities in various subject areas. The first two chapters discuss Palmen's works on cyclones and his early general circulation concepts. The ten chapters following chronicle the advances in understanding cyclones; the theory, structure, and physical processes of cyclones; orographic cyclogenesis; and more. Extratropical Cyclones also contains synoptic case analyses, modeling results, examples of the phenomena discussed, and abundant references. While particular aspects are emphasized in the individual contributions, the book as a whole summarizes the major features of various kinds of extratropical cyclones based on observational analyses, theory and numerical experimentation. This volume is of interest to researchers in dynamic and synoptic meteorology, climatology and mesometeorology, as well as in numerical modeling and weather forecasting. It is also useful for meteorology courses at graduate and upper undergraduate levels.
