​This study shows that the Caspian Sea level time series possess long range dependence even after removing linear trends, based on analyses of the Hurst statistic, the sample autocorrelation functions, and the periodogram of the series. Forecasting performance of ARMA, ARIMA, ARFIMA and Trend Line-ARFIMA (TL-ARFIMA) combination models are investigated. The forecast confidence bands and the forecast updating methodology, provided for ARIMA models in the literature, are modified for the ARFIMA models. Sample autocorrelation functions are utilized to estimate the differencing lengths of the ARFIMA models. The confidence bands of the forecasts are estimated using the probability densities of the residuals without assuming a known distribution. There are no long-term sea level records for the region of Peninsular Malaysia and Malaysia’s Sabah-Sarawak northern region of Borneo Island. In such cases the Global Climate Model (GCM) projections for the 21st century can be downscaled to the Malaysia region by means of regression techniques, utilizing the short records of satellite altimeters in this region against the GCM projections during a mutual observation period. This book will be useful for engineers and researchers working in the areas of applied statistics, climate change, sea level change, time series analysis, applied earth sciences, and nonlinear dynamics.

Weather warnings are important because governments use them to protect life and property. In addition, predicting temperature and precipitation is important for agriculture. As such, weather forecasting is an integral part of meeting targets 2 and 13 of the United Nations’ Sustainable Development Goals: zero hunger and climate action, respectively. This book presents recent developments in scientific research on weather and climate in the extreme environments of Asian, African, and European regions. It provides in-depth case studies from Pakistan, the United States, Vietnam, Nigeria, and Africa. The global and inter-disciplinary results of these studies help us to understand and address the grand challenges of weather as well as its impact on society.

This book provides a comprehensive theory of mono- and multi-fractal traffic, including the basics of long-range dependent time series and 1/f noise, ergodicity and predictability of traffic, traffic modeling and simulation, stationarity tests of traffic, traffic measurement and the anomaly detection of traffic in communications networks. Proving that mono-fractal LRD time series is ergodic, the book exhibits that LRD traffic is stationary. The author shows that the stationarity of multi-fractal traffic relies on observation time scales, and proposes multi-fractional generalized Cauchy processes and modified multi-fractional Gaussian noise. The book also establishes a set of guidelines for determining the record length of traffic in measurement. Moreover, it presents an approach of traffic simulation, as well as the anomaly detection of traffic under distributed-denial-of service attacks. Scholars and graduates studying network traffic in computer science will find the book beneficial.

The enormous progress over the last decades in our understanding of the mechanisms behind the complex system “Earth” is to a large extent based on the availability of enlarged data sets and sophisticated methods for their analysis. Univariate as well as multivariate time series are a particular class of such data which are of special importance for studying the dynamical p- cesses in complex systems. Time series analysis theory and applications in geo- and astrophysics have always been mutually stimulating, starting with classical (linear) problems like the proper estimation of power spectra, which hasbeenputforwardbyUdnyYule(studyingthefeaturesofsunspotactivity) and, later, by John Tukey. In the second half of the 20th century, more and more evidence has been accumulated that most processes in nature are intrinsically non-linear and thus cannot be su?ciently studied by linear statistical methods. With mat- matical developments in the ?elds of dynamic system’s theory, exempli?ed by Edward Lorenz’s pioneering work, and fractal theory, starting with the early fractal concepts inferred by Harold Edwin Hurst from the analysis of geoph- ical time series,nonlinear methods became available for time seriesanalysis as well. Over the last decades, these methods have attracted an increasing int- est in various branches of the earth sciences. The world’s leading associations of geoscientists, the American Geophysical Union (AGU) and the European Geosciences Union (EGU) have reacted to these trends with the formation of special nonlinear focus groups and topical sections, which are actively present at the corresponding annual assemblies.

After the sovjet era and since their independence the new Central Asian countries are rebuilding a system of water resources management: an important challenge for the development of the whole region. The NATO workshop held on 25-27 August 2003 by the Federal Agency for Nature Conservation, Germany and the Siberian Branch of the Russian Academy of Science, attended by experts from five Central Asian countries, Russia, six Western European countries, the US and the UNEP offered water engineers and nature scientists as well as economic and political scientists and practitioners from water administrations and international river commissions to meet in Novosibirsk and develop sustainable approaches in the management of Central Asian water resources. This book presents important aspects of transboundary water resources, i.e. the global water crisis: problems and perspectives; regional experiences in solving water problems in Central Asia; problems and management of transboundary water resources; ecological and economic aspects of water management; scientific analysis and tools of water changes; strategic implications of water access arisen during the workshop. A final recommendation in the area of equitable sharing of benefits, monitoring and data collection as well as proposals for Central Asia transboundary waters programme were set in the book as the main result of the meeting.

The living standards and scale of development around the world are vastly unequal. One notable observation is that much of the poverty-stricken area is located between the tropics of Cancer and Capricorn. By contrast, affluent nations are situated in more temperate zones. Such a phenomenon gives weight to the geography hypothesis that seeks to explain the occurrence of global economic inequality, by placing an emphasis on the importance of natural elements such as location and climate in determining the economic conditions of a nation. This book concentrates exclusively and in depth on the key economic phenomena and factors which shape tropical economies today. It examines contemporary economic problems confronting the tropical countries and provides policy recommendations that align with the United Nations’ Sustainable Development Goals set in the 2030 Agenda. It contains research works and case studies of tropical economies that are related to the area of development and environment economics. The book’s themes range from economic growth, poverty reduction, income inequality, economic globalization, international trade, capital flow, financial development, and institutional development to environmental sustainability within the Tropics. Recognizing the dynamism and diversity of the tropics, the book encompasses empirical and policy analyses that address the key economic issues and challenges in the region so as to provide an important platform from which new policymaking initiatives can flourish. This book will draw readership primarily from the fields of economics and public policy, particularly under the subject areas of development and environment economics, as well as discussions in the sustainability policy space.
