Book Synopsis Tropical Cyclones by : Richard Anthes
Download or read book Tropical Cyclones written by Richard Anthes and published by Springer. This book was released on 2016-06-29 with total page 228 pages. Available in PDF, EPUB and Kindle. 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.
Book Synopsis Uncertainties and Limitations in Simulating Tropical Cyclones by : Asuka Suzuki-Parker
Download or read book Uncertainties and Limitations in Simulating Tropical Cyclones written by Asuka Suzuki-Parker and published by Springer Science & Business Media. This book was released on 2012-01-05 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thesis work was in two major parts: development and testing of a new approach to detecting and tracking tropical cyclones in climate models; and application of an extreme value statistical approach to enable assessment of changes in weather extremes from climate models. The tracking algorithm applied a creative phase-space approach to differentiate between modeled tropical cyclones and their mid-latitude cousins. A feature here was the careful attention to sensitivity to choice of selection parameters, which is considerable. The major finding was that the changes over time were relatively insensitive to these details. This new approach will improve and add confidence to future assessments of climate impacts on hurricanes. The extremes approach utilized the Generalized Pareto Distribution (one of the standard approaches to statistics of extremes) applied to present and future hurricane distributions as modeled by a regional climate model, then applied the changes to current observations to extract the changes in the extremes. Since climate models cannot resolve these extremes directly, this provides an excellent method of determining weather extremes in general. This is of considerable societal importance as we are most vulnerable to such extremes and knowledge of their changes enables improved planning and adaptation strategies.

Book Synopsis Hurricanes and Climate Change by : Jennifer M. Collins
Download or read book Hurricanes and Climate Change written by Jennifer M. Collins and published by Springer. This book was released on 2017-02-20 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides research that shows tropical cyclones are more powerful than in the past with the most dramatic increases occurring over the North Atlantic and with the strongest hurricanes. Although such increases are correlated with warming oceans and are consistent with the thermodynamic theory of hurricane intensity, there remains doubt about the interpretation, integrity, and meaning of these results. Arising from the 5th International Summit on Hurricanes and Climate Change, this book contains new research on topics related to hurricanes and climate change. Bringing together international leading academics and researchers on various sides of the debate, the book discusses new research and expresses opinions about what is happening and what might happen in the future with regard to regional and global hurricane (tropical cyclone) activity.

Book Synopsis Environmental Influences on Rapid Intensity Changes in Tropical Cyclones - a Case Study by :
Download or read book Environmental Influences on Rapid Intensity Changes in Tropical Cyclones - a Case Study written by and published by . This book was released on 2008 with total page pages. 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.

Book Synopsis Weather Disasters in the South China Sea and Surrounding Regions: Observations, Theories, Data Assimilation, and Numerical Forecasting by : Jianjun Xu
Download or read book Weather Disasters in the South China Sea and Surrounding Regions: Observations, Theories, Data Assimilation, and Numerical Forecasting written by Jianjun Xu and published by Frontiers Media SA. This book was released on 2023-08-28 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The South China Sea (SCS) is the linkage between the western Pacific Ocean and the Indian Ocean. Its weather/climate variations are regarded as an important factor influencing social and economic development. The SCS and its surrounding regions suffer from various weather disasters (e.g., typhoons, extreme rainfall, sea fog, severe convection, tornado, and wind hazards), which are serious threats to life and property. As such, accurate nowcasting is life-critical in this area. However, it is still a worldwide challenge to improve the forecast accuracy due to less understanding of the formation mechanism, evolution pattern, internal structure, and physical processes. As a dominant physical process, the ocean-atmosphere interaction plays an important role in affecting the weather/climate system and disasters over the SCS and surrounding regions, particularly vertical mixing between the interface of ocean and atmosphere. This research topic aims to provide an in-depth understanding of the physical processes related to these disasters, applications of data assimilation, and the development of forecasting techniques, which are essential to enhance disaster prevention and mitigation capabilities. In addition, in-depth research of these disasters and their impacts could help to uncover the hazard-causing characteristics and establish a corresponding risk assessment system.

Book excerpt: Technology has propelled the atmospheric sciences from a fledgling discipline to a global enterprise. Findings in this field shape a broad spectrum of decisions--what to wear outdoors, whether aircraft should fly, how to deal with the issue of climate change, and more. This book presents a comprehensive assessment of the atmospheric sciences and offers a vision for the future and a range of recommendations for federal authorities, the scientific community, and education administrators. How does atmospheric science contribute to national well-being? In the context of this question, the panel identifies imperatives in scientific observation, recommends directions for modeling and forecasting research, and examines management issues, including the growing problem of weather data availability. Five subdisciplines--physics, chemistry, dynamics and weather forecasting, upper atmosphere and near-earth space physics, climate and climate change--and their status as the science enters the twenty-first century are examined in detail, including recommendations for research. This readable book will be of interest to public-sector policy framers and private-sector decisionmakers as well as researchers, educators, and students in the atmospheric sciences.
Book Synopsis The Vertical Structure of Tangential Winds in Tropical Cyclones: Observations, Theory, and Numerical Simulations by : Daniel Philip Stern
Download or read book The Vertical Structure of Tangential Winds in Tropical Cyclones: Observations, Theory, and Numerical Simulations written by Daniel Philip Stern and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The vertical structure of the tangential wind field in tropical cyclones is investigated through observations, theory, and numerical simulations. First, a dataset of Doppler radar wind swaths obtained from NOAA/AOML/HRD is used to create azimuthal mean tangential wind fields for 7 storms on 17 different days. Three conventional wisdoms of vertical structure are reexamined: the outward slope of the Radius of Maximum Winds (RMW) decreases with increasing intensity, the slope increases with the size of the RMW, and the RMW is a surface of constant absolute angular momentum (M). The slopes of the RMW and of M surfaces are objectively determined. The slopes are found to increase linearly with the size of the low-level RMW, and to be independent of the intensity of the storm. While the RMW is approximately an M surface, M systematically decreases with height along the RMW. The steady-state analytical theory of Emanuel (1986) is shown to make specific predictions regarding the vertical structure of tropical cyclones. It is found that in this model, the slope of the RMW is a linear function of its size and is independent of intensity, and that the RMW is almost exactly an M surface. A simple time-dependent model which is governed by the same assumptions as the analytical theory yields the same results. Idealized hurricane simulations are conducted using the Weather Research and Forecasting (WRF) model. The assumptions of Emanuel2s theory, slantwise moist neutrality and thermal wind balance, are both found to be violated. Nevertheless, the vertical structure of the wind field itself is generally well predicted by the theory. The percentage rate at which the winds decay with height is found to be nearly independent of both size and intensity, in agreement with observations and theory. Deviations from this decay profile are shown to be due to gradient wind imbalance. The slope of the RMW increases linearly with its size, but is systematically too large compared to observations. Also in contrast to observations, M generally increases with height along the RMW.
