This book was released on 1998-03-01 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Subjective and objective analyses of satellite scatterometer near- surface winds are utilized to estimate tropical cyclone (TC) critical wind radii and size over a region of the western North Pacific. An outer wind profile assuming a linear slope dependent on the TC latitude is used to determine the radial extent of cyclonic winds beyond a set radius. Inside the set radius, a partial conservation of angular momentum is assumed into the TC maximum wind radius and the 35, -50, and 100-kt radii are calculated. Nine TCs were investigated during the operating period of the NASA scatterometer (NSCAT). Critical wind radii values in four quadrants (front, right, rear, and left) of the TCs are found to be comparable to the Joint Typhoon Warning Center (JTWC) critical wind radii values issued in warnings. The radial extent of cyclonic winds are also comparable to the radius of zero winds estimated by determining where the cyclonic flow turned to anticyclonic flow in the NSCAT sea-surface wind swaths.

This book was released on 1979 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Up-to-date results of recent tropical cyclone research at Colorado State University are presented. Particular attention is paid to new findings which impact on tropical cyclone analysis and forecasting efforts. Observational studies using large amounts of composited rawinsonde, satellite, and aircraft flight data have been performed to analyze global aspects of tropical cyclone occurrences, physical processes of tropical cyclone genesis, tropical cyclone intensity change, environmental factors influencing tropical cyclone turning motion 24-36 hours before the turn takes place, tropical cyclone intensity determination from upper tropospheric reconnaissance, and the diurnal variations of vertical motion in tropical weather systems.

This book was released on 2016-11-21 with total page 762 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals primarily with monitoring, prediction and understanding of Tropical Cyclones (TCs). It was envisioned to serve as a teaching and reference resource at universities and academic institutions for researchers and post-graduate students. It has been designed to provide a broad outlook on recent advances in observations, assimilation and modeling of TCs with detailed and advanced information on genesis, intensification, movement and storm surge prediction. Specifically, it focuses on (i) state-of-the-art observations for advancing TC research, (ii) advances in numerical weather prediction for TCs, (iii) advanced assimilation and vortex initialization techniques, (iv) ocean coupling, (v) current capabilities to predict TCs, and (vi) advanced research in physical and dynamical processes in TCs. The chapters in the book are authored by leading international experts from academic, research and operational environments. The book is also expected to stimulate critical thinking for cyclone forecasters and researchers, managers, policy makers, and graduate and post-graduate students to carry out future research in the field of TCs.
Download or read book Tropical Cyclone Modification written by Robert C. Sheets and published by . This book was released on 1981 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Project Stormfury modification theory, its physical basis, and the experiment design are described, and the possible effects of such experiments on tropical cyclone motion, rainfall, wind fields, and storm surge are examined. Studies of natural storm variability, exploratory experiments, sensitivity tests, numerical simulations, and theoretical calculations indicate that experiments conducted according to the Stormfury hypothesis could result in reductions of 10% to 15% in the maximum windspeed and associated damage reductions of 20% to 60%, with no apparent significant and/or detectable effect on storm motion or net rainfall accumulated areawide or at specific locations for a moving storm.

Book excerpt: This book studies the pitfalls of regional climate models in simulating track and intensity of tropical cyclone over western North Pacific for the East Asian summer monsoon climate.A number of sensitivity experiments related to tropical cyclone simulation with different model configurations and model physical schemes, including model resolution, model lateral boundary condition, effect of sea surface temperature, cumulus parameterization scheme and model microphysics scheme, as well as the features and the failure of tropical cyclone simulation in regional climate models were carefully analyzed with model output with high temporal resolution, to investigate shortcomings of the models, so as to come up with better models to simulate and study tropical cyclone track and intensity.The book is suitable for graduate students in meteorology with focuses in the tropical cyclone simulation, as well as professionals devoted to model development and study of tropical cyclone activities.
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.
Download or read book Tropical Cyclone Wind Probability Forecasting WINDP written by Jerry D. Jarrell and published by . This book was released on 1981 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of a model to estimate 30 and 50 kt wind probabilities from tropical cyclone forecasts is described. Some examples to illustrate the use of probabilities are discussed. The model is based on position forecast errors, which are used to determine the probability of a cyclone occupying a particular geographical position, and on wind profile errors. Wind profile errors consist of errors in the forecast maximum wind and errors in the forecast radius of 30 and 50 kt winds. The profile errors are used to estimate the probability of 30 an 50 kt winds occurring at a point, given that the cyclone occupies a particular position. These position and wind probability elements are combined by using an assumption of independence which is supported by correlation coefficients. The model, which includes features of the earlier strike probability model, is tested on independent data. Test results are shown to illustrate good agreement between forecast probability and the frequency of occurrence of 30 and 50 kt winds. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This book highlights some of the most recent research in the climatological behavior of tropical cyclones as well as the dynamics, predictability, and character of these storms as derived using remote sensing techniques. Also included in this book is a review of the interaction between tropical cyclones and coastal ocean dynamics in the Northwest Pacific and an evaluation of the performance of CMIP6 models in replicating the current climate using accumulated cyclone energy. The latter demonstrates how the climate may change in the future. This book can be a useful resource for those studying the character of these storms, especially those with the goal of anticipating their future occurrence in both the short and climatological range and their associated hazards.
