This book was released on 2015 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical cyclone intensity is determined by the amount of heat and moisture it absorbs in the lower portion of the atmosphere. Thus, it is imperative to achieve a greater understanding of kinematic and thermodynamic features which serve to promote or hinder the intensification process. The analysis utilizes a 16 year dropsonde dataset containing over 13,681 quality controlled dropsonde profiles from the inner core and environment surrounding 120 different tropical cyclones. This data was used to classify strengthening and weakening tropical cyclones as well as examine their respective wind, moisture and temperature characteristics. When compared to weakening tropical cyclones, strengthening storms showed differences in (1) tangential wind speed, (2) tangential wind structure in both the horizontal and vertical domain, (3) radial outflow structure and (4) relative humidity structure which could serve as useful diagnostic tools when evaluating tropical cyclone status.

Book excerpt: Tropical Cyclones and hurricanes, long feared for the death and destruction that often accompanies them, are among the most fascinating of atmospheric phenomena. Created by thermodynamic processes, they unleash vast amounts of energy and influence a wide variety of natural processes along their paths. Richard Anthes tells the story of tropical cyclones creation and destruction, of meteorology's successes in understanding, modeling and predicting their behavior, and of the attempts to modify them. The book begins with a lively introduction to hurricanes, their awesome power, and their effects on individuals and societies in the past and present. The characteristics of the mature hurricane are revealed by consideration of rawinsonde, aircraft and satellite data. The physical processes responsible for the development and maintenance of tropical cyclones are treated comprehensively, and illustrated with both qualitative and quantitative examples. The role of the planetary boundary layer, cumulus convection and radiation are all discussed in detail. Progress in numerical simulation of tropical cyclones is carefully reviewed. Modern, three-dimensional models succeed in simulating observed features such as the eye and spiral rain bands and in predicting storm motion over time intervals of three days. Current capabilities to predict and modify hurricanes and tropical cyclones are fully examined. The methods and difficulties of operational forecasting, the economic aspects of storm predictions, and the trends in accuracy of offical forecasts are all considered. The potential benefits and scientific problems associated with hurricane modification are discussed as part of a review of experimental and theoretical results on the consquences of seeding hurricane clouds. A unique feature of the book is a thorough treatment of the interactions between storm and ocean, with both observations and thery being integrated to provide a complete description.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This book surveys the past, present, and potential future variability of hurricanes and typhoons on a variety of timescales using newly developed approaches based on geological and archival records, in addition to more traditional approaches based on the analysis of the historical record of tropical cyclone tracks. A unique aspect of the book is that it provides an overview of the developing field of paleotempestology, which uses geological, biological, and documentary evidence to reconstruct prehistoric changes in hurricane landfall. The book also presents a particularly wide sampling of ongoing efforts to extend the best track data sets using historical material from many sources, including Chinese archives, British naval logbooks, Spanish colonial records, and early diaries from South Carolina. The book will be of particular interest to tropical meteorologists, geologists, and climatologists as well as to the catastrophe reinsurance industry, graduate students in meteorology, and public employees active in planning and emergency management.

Book excerpt: The long-term goals of our research are to understand the interactions between tropical cyclones and their surroundings, and how such interactions influence tropical cyclone structure and intensity. The primary objective of this proposal was to understand the interactions of upper tropospheric potential vorticity centers and tropical cyclones, and to develop a "path to operations" that will allow prediction of tropical cyclone intensity change during such interactions. This objective is an extension of our previous ONR-funded work. The second objective was to understand the mechanisms behind the clustering of tropical cyclone occurrence in time, with the ultimate goal of predicting the presence of multiple tropical cyclones in advance. This represents a new initiative. Early studies have been for the eastern Pacific Ocean, but are now being extended to the western Pacific.

Available in PDF, EPUB and Kindle. Book excerpt: Hurricane Bret underwent a rapid intensification (RI) and subsequent weakening between 1200 UTC August 21 and 1200 UTC August 22, 1999, before it made landfall as a category 3 hurricane on the Texas coast 12 h later. Its minimum sea-level pressure dropped 35 hPa from 979 to 944 hPa within 24 h. During this period, aircraft of the National Oceanographic and Atmospheric Administration (NOAA) flew several research missions that sampled the environment and inner core of the storm. These data sets combined with gridded data from the National Centers for Environmental Prediction's (NCEP) Global Model and the National Center for Atmospheric Research (NCAR) reanalyses are used to document the atmospheric and oceanic environments of the tropical cyclone (TC) as well as their relation to the observed structural and intensity changes. Bret's RI was linked to movement over a warm ocean eddy and high sea surface temperatures (SSTs) in the Gulf of Mexico coupled with a simultaneous decrease in vertical wind shear. SSTs at the beginning of the storm2s RI were approximately 29 degrees Celcius and steadily increased to 30 degrees Celcius as it moved northward. The vertical wind shear relaxed to less than 10 kt during this time. Mean values of oceanic heat content (OHC) beneath the storm were about 20 % higher at the beginning of the RI period than 6 h before. Cooling of near-coastal shelf waters (to between 25 and 26 degrees Celcius) by pre-storm mixing combined with an increase in vertical wind shear were responsible for the weakening of the storm. The available observations suggested that intrusion of dry air into the circulation core did not contribute to the intensity evolution. In order to quantitatively describe the influence of environmental conditions on the intensity forecast, sensitivity studies with the Statistical Hurricane Intensity Prediction Scheme (SHIPS) model were conducted. Four different cases with modified vertical wind shear and/or SSTs were studied. Differences between all cases were relatively small due to the model design, but much cooler prescribed SSTs resulted in the greatest intensity changes. Model runs with idealized environmental conditions demonstrated the model2s general lack of capability to forecast RIs and also stressed the need of more accurate SST observations in the coastal shelf regions when predicting the intensity of landfalling TCs.
