Book Description
Understanding climate change requires analysis of its effects in specific contexts, and the case studies in this volume offer examples of such issues. Its chapters cover tropical cyclones in East Asia, study of a fossil in Brazils Araripe Basin and the fractal nature of band-thickness in an iron formation of Canadas Northwest Territories. One chapter examines the presence of trace elements and palynomorphs in the sediments of a tropical urban pond. Examples of technologies used include RS- GIS to map lineaments for groundwater targeting and sustainable water-resource management, the ALADIN numerical weather-prediction model used to forecast weather and use of grids in numerical weather and climate models. Finally, one chapter models sea level rises resulting from ice sheets melting.

Book Description
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 Description
Severe tropical storms and typhoons hit East Asia mainly from summer to autumn every year, bringing abundant water resources to the inhabitants. However, typhoons are among the most devastating of all natural disasters, causing the loss of many lives and giving rise to large economic losses. In Japan, the number of fatalities as a result of typhoons has been reduced because of new observation techniques, such as rawinsonde, meteorological satellites, radar, numerical forecasts, information services through radio and television, and the service of structures including river improvement and erosion and torrent control works. We have found, however, that recent severe tropical storms, the cyclone in Bangladesh in 1998 and Hurricane Katrina in the United States in 2005, generated massive destruction. In regard to typhoons, several time-period variations appear in the genetic numbers during 1951-2005: interannual frequency, interdecadal frequency, and long-term trends. This suggests that typhoons and hurricanes have become activated and this should relate to the recent global warming over the past 30 years. Therefore it is necessary to confirm how tropical storm activity will change in the future as a result of climate variability and fluctuation. The third report of the IPCC (the United Nation s Intergovernmental Panel on Climate Change) indicates that water-related disasters resulting from severe weather will change in quality in association with global warming. With the recent development of satellite remote sensing, ground and aircraft observations, numerical simulation techniques, and the investigations of global climate change, the relationship between global warming and tropical storms and, furthermore, their related disasters are making progress. Under these situations, our group planned to conduct a project, entitled Study on extreme weather events and water-related disasters as a result of climate variability and changes, to make use of projecting a long-term change of water-related disasters from 2002 to 2004. Based on our group s recent research and the related studies of other institute researchers in Japan, we prepared the results of tropical cyclones as recent reviews for publication as a book, Water-Related Disasters; Climate Variability and Change: Results of Severe Tropical Storms in East Asia. In this work, we introduce new numerical and data-analysis research concerning the relationship between East Asia s climate variability and changes and tropical storms, the storms by themselves, and the water-related disasters they cause. The first paper, Climate Changes and Tropical Storms in the Western North Pacific, reviews the general overview of typhoon classifications, developing mechanisms, structures, climatologies, and their disasters. The second paper, The Structure of Tropical Cyclones, addresses three stages: developing stage in general, mature stage, and developing stage in detail. The third paper, Extratropical Response to Typhoon-Induced Convective Heating over the Western North Pacific in Summer, is a new insight into how the typhoons are generated over the tropics and how they affect the midlatitude area through teleconnection. Paper number four, The Relationship Between ENSO and a Tropical Cyclone Simulated in a CGCM, deals with the characteristics of typhoon activity during the El Niño and La Niña periods. The fifth paper, Global Warming and Tropical Storms. Simulations Using General Circulation Models, presents the hot topic of tropical storm activity when global warming occurs. Paper number six, Potential Hydrologic Change Resulting from Greenhouse Warming, is a downscaling result of CGCM to a regional atmospheric model for global warming simulation. The seventh paper, The Influences of Climate Change in the Frequencies of Storm Rainfalls and Flood Disasters, addresses the particularly heavy rain caused by ENSO and typhoons in Japan. This paper also describes the impacts of global warming on heavy precipitation frequency and the flood risk of the Tama River Basin in Japan. The final paper in the book, Changes in Wave Climate in the Western North Pacific, presents a study of interannual variability and a future projection of summertime wave heights in the western North Pacific. We hope this book will be read and referred to not only by researchers of tropical cyclones and by climatologists, but also by the wider scientific community of researchers, science managers, and graduate students.

Book Description
Essay from the year 2011 in the subject Geography / Earth Science - Meteorology, Aeronomy, Climatology, grade: 11.0, University of Exeter, language: English, abstract: Since tropical cyclones(TCs) are one of the major geophysical cause of loss of life and property, it is important to understand if there is any change in the frequency and intensity of TCs due to anthropogenic climate change. IPCC considers 0.25-0.5 C increase in warming over tropical oceans over the past few decades due to increase in greenhouse gas concentration over past 50years. During 6th International Workshop on Tropical Cyclones, a statement was released on the connection between the TCs and anthropogenic climate change. The statement was in response to the increase in number of recent high-impact TC events which includes, 10 land falling Tcs in Japan in 2004, 5 TCs affecting the Cook island in a five week period during 2005, cyclone Gafilo in Madagascar in 2004, cyclone Larry in Australia in 2006, typhoon Saomai in China in 2006, and violently active Atlantic TC season during the period of 2004 to 2005, including the catastrophic socioeconomic impact of Hurricane Katrina. A few recent articles [1] have noted a large increase in TC’s intensity, frequency and wind-speeds in some regions during past 5 decades, which could be attributed to the increase in the concentration of green house gases in past 50years. However, other studies explain this noticed increase as a result of better observations made and instruments used, making it easier to detect TCs. Consensus statement by the International workshop on TC-6 reported uncertain conclusions about the influence of climate change on TC after taking into account evidence both for and against. It was concluded that no TC could be solely attributed to the anthropogenic climate change. Model and theory predicts 3-5% increase in wind speed per degree C increase in SST. But, there is inconsistency between the small change in wind speed projected by theory and modelling versus large variations reported by some observational studies. Significant limitation of measurements over some regions make detection of trends difficult. It was suggested that if increase in SST continues, susceptibility to TC storm surge flooding would strengthen.

Book Description
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.
