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.

Download or read book Hurricanes written by Henry F. Diaz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hurricanes of the North Atlantic Ocean have left their imprint on the landscape and human cultures for thousands of years. In modern times, fewer lifes have been lost due, in part, to the development of modern communication systems, and to improved understanding of the mechanisms of storm formation and movement. However, the immense growth of human populations in coastal areas, which are at risk to hurricanes, has resulted in very large increases in the amount of property damage sustained in the last decade in the Atlantic, Gulf of Mexico and Caribbean regions. This book is of interest to climatologists and meteorologists and as source of information for policymakers and emergency management planners.

Available in PDF, EPUB and Kindle. Book excerpt: The formation of tropical cyclones in unfavorable large-scale environments remains a challenge for researchers and forecasters. This thesis provides an investigation of the genesis of Tropical Storm Cindy (2017) using a combination of aircraft measurements collected during the Convective Processes EXperiment (CPEX) field campaign and a fully-coupled atmosphere-wave-ocean numerical simulation. Prior to TC genesis, a shallow cyclonic vortex is embedded in a deep layer of W/SW winds associated with an upper-level trough. Despite vertical wind shear greater than 20 m/s, low mid-tropospheric relative humidity and poorly organized convection, Cindy formed at 1800 UTC 20 June 2017 in the central Gulf of Mexico. At the time of genesis, the dropsondes and the numerical simulation reveal the presence of subsidence within the developing storm. Descent produces a temperature and moisture perturbation maximized in the 2-2.5 km layer. In the hours prior to TC genesis, 2500 m temperature increases by 5 °C and the dew point temperature depression grows larger than 8 °C. At TC genesis, the subsidence-induced virtual temperature perturbation in the 1.5-3.5 km layer accounts for 50% of the sea-level pressure perturbation and for more than 65 % of the sea-level pressure drop during the genesis stage. A backward trajectory analysis indicates that the air parcels warm by 14 °C in response to a 1.8 km descent along the upshear flank of the storm, with an estimated subsidence rate of nearly 6 cm/s.

This book was released on 2022-03-10 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive summary of research on tropical cyclone variability at various time scales, from intraseasonal and interannual to interdecadal and centennial. It covers the fundamental theory, statistics and numerical modelling techniques used when considering climate variability in relation to tropical cyclone activity. Major climate oscillations including the Madden-Julian, El Niño, Atlantic Meridional Mode, and Pacific Decadal oscillations are covered, and their impacts on tropical cyclone activity in the Pacific and Atlantic oceans are discussed. Hurricane landfalls in the United States, Caribbean and East Asia are also considered. Climate models and numerical simulations are used to show how prediction models of tropical cyclones are developed, while looking to the future, particular attention is paid to predicting how tropical cyclones will change in response to increased concentrations of greenhouse gases. This book ideal for researchers and practitioners in atmospheric science, climatology, oceanography and civil and environmental engineering.
Download or read book Understanding Environmental Favorability for Tropical Cyclogenesis by Analysis of Threshold Parameters written by Michael McGauley and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: As the climate changes, the ability to predict changes in the frequency of tropical cyclogenesis is becoming of increasing interest. A unique approach is proposed that utilizes threshold values in potential intensity, wind shear, vorticity, and normalized saturation deficit. Prior statistical methods generally involve creating an index or equation based on averages of important meteorological parameters for a given region. The new method assumes that threshold values exist for each important parameter for which cyclogenesis is unlikely to develop. This technique is distinct from previous approaches that seek to determine how each of these parameters interdependently favors cyclogenesis. To determine three of the individual threshold values (shear, potential intensity, and vorticity), an idealized climate is first established that represents the most advantageous but realistic (MABR) environment. An initial numerical simulation of tropical cyclone genesis in the MABR environment confirms that it is highly favorable for cyclogenesis. Subsequent numerical simulations vary each parameter individually until no tropical cyclone develops, thereby determining the three threshold values. The new method of point downscaling, whereby background meteorological features are represented by a single vertical profile, is used in the numerical simulations to greatly simplify the approach. The remaining threshold parameter (normalized saturation deficit) is determined by analyzing the climatological record and choosing a value that is statistically observed to prevent cyclogenesis. Once each threshold value is determined, the fraction of time each is exceeded in the location of interest is computed from the reanalysis dataset. The product of each fraction for each of the relevant parameters then gives a statistical probability as to the likelihood of cyclogenesis. For predicting regional and monthly variations in frequency of genesis, this approach is shown to generally meet or exceed the predictive skills of earlier statistical attempts with some failure only during several off-season months. This method also provides a more intuitive rationale of the results. Since the genesis frequency index (GFI) method has shown to meet or exceed the predictive skill of other indices, analysis of the impact of El Niño and La Niña on cyclogenesis is performed for each of the six ocean basins. Although the GFI method generally corroborates other studies that have shown El Niño years are conducive for storms in the eastern Pacific and detrimental to storms in the Atlantic, the GFI method reveals important differences within each basin that other studies have not found. In particular the GFI method shows a region north of South America, known for its paucity of storms regardless of global weather phenomenon, is not greatly affected by El Niño events reinforcing the claim the GFI method is a more robust predictor of cyclogenesis. The first calculation of GFI used NCEP reanalysis to determine each of the four fractions (or frequencies). Since the NCEP reanalysis data has shown to underestimate mid and upper-level humidity, two other data sources are used to determine if a more accurate humidity profile can improve the GFI method. Although some of the basins did show an improved skill, there was not a global improvement from a particular data set and therefore the reanalysis data set chosen to calculate GFI was not deemed an important consideration. In an attempt to explain the threshold nature of cyclogenesis, analyses of momentum and moisture budgets on a nascent vortex were performed. Although momentum budgets revealed that friction did not contribute significantly to whether the storm would develop or not, no other processes revealed a threshold-like behavior in cyclogenesis. The moisture budgets, however, revealed an inverse relationship of advected water vapor to latitude. The cause of this was found to be that radial winds are significantly affected by the Coriolis parameter and at higher latitudes these winds (and therefore advected water vapor) were reduced. Since a developing storm requires the latent heat release from moisture and with less moisture available at higher latitudes, the storm must be more efficient at converting this heat to kinetic energy. Investigation into inertial stability found that although the Coriolis parameter was responsible for reduced radial winds at higher latitudes, it was also responsible for the increased stability. With increased stability, the heat produced within the inner vortex was confined to the same region. At low latitudes, even though there was abundant moisture, the inertial stability was too low to allow development, therefore revealing part of the threshold-like behavior of cyclogenesis.
