This book was released on 2018-08-16 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the interval of 1944-1997, 120 intense hurricanes (i.e., those of category 3 or higher on the Saffir-Simpson hurricane damage potential scale) were observed in the Atlantic basin, having an annual frequency of 0-7 events per year, being more active prior to the mid 1960's than thereafter (hence a possible two-state division: more active versus less active), and being preferentially lower during El Nino years as compared to non-El Nino years. Because decadal averages of the frequency of intense hurricanes closely resemble those of average temperature anomalies for northern hemispheric and global standards and of the average temperature at the Armagh Observatory (Northern Ireland), a proxy for climatic change, it is inferred that the long-term trends of the annual frequency of intense hurricanes and temperature may be statistically related. Indeed, on the basis of 4- and 10-yr moving averages, one finds that there exists strong linear associations between the annual frequency of intense hurricanes in the Atlantic basin and temperature (specially, when temperature slightly leads). Because the long-term leading trends of temperature are now decidedly upward, beginning about the mid 1980's, it is inferred that the long-term consequential trends of the annual frequency of intense hurricanes should now also be upward, having begun near 1990, suggesting that a return to the more active state probably has already occurred. However, because of the anomalous El Nino activity of the early to mid 1990's, the switch from the less active to the more active state essentially went unnoticed (a marked increase in the number of intense hurricanes was not observed until the 1995 and 1996 hurricane seasons, following the end of the anomalous El Nino activity). Presuming that a return to the more active state has, indeed, occurred, one expects the number of seasonal intense hurricanes during the present epoch (continuing through about 2012) to usually be higher than average (i.e., ..

Download or read book Hurricanes of the North Atlantic written by James B. Elsner and published by Oxford University Press. This book was released on 1999-06-10 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: Called the greatest storms on the planet, hurricanes of the North Atlantic Ocean often cause tremendous social and economic upheaval in the United States, Mexico, and the Caribbean. And with the increasing development of coastal areas, the impact of these storms will likely increase. This book provides a comprehensive analysis of North Atlantic hurricanes and what they mean to society. It is intended as an intermediary between hurricane climate research and the users of hurricane information. Topics include the climatology of tropical cyclones in general and those of the North Atlantic in particular; the major North Atlantic hurricanes, focusing on U.S. landfalling storms; the prediction models used in forecasting; and societal vulnerability to hurricanes, including ideas for modeling the relationship between climatological data and analysis in the social and economic sciences.
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.
Download or read book Recent Hurricane Research written by Anthony Lupo and published by BoD – Books on Demand. This book was released on 2011-04-19 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents recent research on tropical cyclones and their impact, and a wide range of topics are covered. An updated global climatology is presented, including the global occurrence of tropical cyclones and the terrestrial factors that may contribute to the variability and long-term trends in their occurrence. Research also examines long term trends in tropical cyclone occurrences and intensity as related to solar activity, while other research discusses the impact climate change may have on these storms. The dynamics and structure of tropical cyclones are studied, with traditional diagnostics employed to examine these as well as more modern approaches in examining their thermodynamics. The book aptly demonstrates how new research into short-range forecasting of tropical cyclone tracks and intensities using satellite information has led to significant improvements. In looking at societal and ecological risks, and damage assessment, authors investigate the use of technology for anticipating, and later evaluating, the amount of damage that is done to human society, watersheds, and forests by land-falling storms. The economic and ecological vulnerability of coastal regions are also studied and are supported by case studies which examine the potential hazards related to the evacuation of populated areas, including medical facilities. These studies provide decision makers with a potential basis for developing improved evacuation techniques.
Download or read book Hurricanes and Climate Change written by James B. Elsner and published by Springer Science & Business Media. This book was released on 2010-01-23 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies suggest that tropical cyclones are more powerful than in the past with the most dramatic increase in the North Atlantic. The increase is correlated with an increase in ocean temperature. A debate concerns the nature of these increases with some scientists attributing them to a natural climate fluctuation and others suggesting climate change related to anthropogenic increases in forcing from greenhouse gases. A Summit on Hurricanes and Climate Change was held during the spring of 2007 on the island of Crete that brought together leading academics and researchers on both sides of the scientific debate to discuss new research and express opinions about what will happen in the future with regard to hurricane activity. This proceedings volume highlights the state-of-the-science research into various aspects of the hurricane-climate connection. It is likely that the science presented here will lead to new research that will help answer crucial questions about our sustainable future.
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.

Book excerpt: Today, El Niño refers to the extreme warming episodes of the globally effective coupled ocean-atmospheric interaction commonly known as ENSO (i.e., "El Nino-Southern Oscillation"). Concerning its observed decadal frequency and severity, El Nino during the 1990's has often been regarded as being anomalous. Results of analysis herein however, appear to mitigate this belief.
Download or read book The Great Hurricane of 1780 written by Wayne Neely and published by iUniverse. This book was released on 2012-09-17 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Great Hurricane of 1780," also known as Hurricane San Calixto II, is one of the most powerful and deadliest North Atlantic hurricanes on record. Often regarded as a cataclysmic hurricane, the storm's worst effects were experienced on October 10, 1780. In "The Great Hurricane of 1780," author Wayne Neely chronicles the chaos and destruction it brought to the Caribbean. This storm was likely generated in the mid Atlantic, not far from the equator; it was first felt in Barbados, where just about every tree and house on the island was blown down. The storm passed through the Lesser Antilles and a small portion of the Greater Antilles in the Caribbean between October 10 and October 16 of 1780.Because the storm hit several of the most populous islands in the Caribbean, the death toll was very high. The official death toll was approximately 22,000 people but some historians have put the death toll as high as 27,500. Specifics on the hurricane's track and strength are unclear since the official North Atlantic hurricane database only goes back as far as 1851. Even so, it is a fact that this hurricane had a tremendous impact on economies in the Caribbean and parts of North America, and perhaps also played a major role in the outcome of the American Revolution. This thoroughly researched history considers the intense storm and its aftermath, offering an exploration of an important historical weather event that has been neglected in previous study.
Download or read book 2020 Atlantic Hurricane Season written by and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2020 Atlantic hurricane season was extremely active, with 30 "named storms" (tropical storm or higher strength), including 13 hurricanes, which is more than double the long-term average of 12 named storms and 6 hurricanes. Several records were set (e.g. number of named storms) and the Greek alphabet was used for the second time on record (in the past only in 2005) to assign a name to the tropical storms and hurricanes. The Atlantic hurricane season (North Atlantic Ocean, Caribbean Sea and Gulf of Mexico) officially starts on 1 June and ends on 30 November, with the highest activity from August to late October. However, in 2020, two tropical storms formed in May, before the start of the season, and the last month of the season was particularly active with two major hurricanes: ETA and IOTA. The 2020 season is the fifth consecutive Atlantic hurricane season above-average and several conditions contributed to make the 2020 record-breaking season possible, including La Niña which developed during the peak of the hurricane season and enhanced the hurricane activity in this basin. Every year the tropical cyclones (TCs) affect millions of people around the world, including several vulnerable islands of the Caribbean area and Central America, leaving a trail of destruction that requires the international assistance of the humanitarian community. In this report, the 2016-2020 Atlantic hurricane seasons and the extremely active 2005 season have been analysed, considering the impact on the affected areas and the international humanitarian support. Moreover, in 2020, the COVID-19 pandemic emergency influenced the TCs preparedness and response activities, creating a multi-risk scenario and increasing the vulnerability. Since 2011, the Global Disasters Alerts and Coordination System (GDACS) estimates the impact of all the TCs occurring worldwide and timely issued RED alerts for the most destructive events, like for ETA and IOTA in 2020, which devastated Central America.

Download or read book Hurricanes and Typhoons written by Richard J. Murnane and published by Columbia University Press. This book was released on 2004-12-01 with total page 494 pages. 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.
