This book examines the meteorological phenomenon known as Western Disturbances (WDs) and traces their influence on the Indian subcontinent. It fully details the unique characteristics and dynamics of these disturbances, which produce large-scale instabilities in the atmosphere over northern India due to the orographic influence of the Himalayas. The authors first present a definition of the phenomenon and then go on to detail their structure and migration. Topics include dynamics, energetics and thermodynamics; modelling studies; land-use and land-cover interactions; and WDs in the changing climate. In addition, coverage outlines how WDs interact with and influence other weather systems throughout the four seasons of Indian climate: winter, pre-monsoon, monsoon and post-monsoon. It places special emphasis on wintertime dynamics since WDs significantly contribute to the precipitation in India during this time. The authors explain why this period should be termed "Indian winter monsoon" and differentiate it from the northeast monsoon which so far is the prevalent term used in the region's meteorological parlance. Complete with detailed illustrations and case studies, this monograph will help researchers and students gain a fundamental understanding of these important storms. This knowledge is essential not only for short–term and seasonal hydrometeorological forecasting but also for the assessment of regional climate change and its impacts.

It is no longer disputed nowadays that mathematical statistics is the main tool to be used in climatology. Mathematical statistics is in fact the science of random models and the purpose of the statistics analysis of series of observations is to from among the models which science makes available, the one which bes represents the behaviour of the observed phenomenon. Thi atitude may be justifed in two ways. From the theoretical point of view, the representation of the observad phenomenon by a model depending on aminimum number of paramenters anables objective statistical conslusions to be compared with the physical theories put forward, iether to confirm their validity or to reveal weaknesse: thus statistical analysis appears as a means for progress in the ofresearch. From the practical point view, due to the efficiency of methods of statistical analysis, their utilization ensures that the best use is made of the information accumulated dy the series of observations and that the maximum benefic will be derived from the capital represented by this information. If we think of the investments and operational cost which have been approved for the acquisition of the series of observations and of the economic value of these, which is continually demonstrated in the applications of meteorology and climatology, the necessity of such a position becomes obvious.

Entropy Theory and its Application in Environmental and Water Engineering responds to the need for a book that deals with basic concepts of entropy theory from a hydrologic and water engineering perspective and then for a book that deals with applications of these concepts to a range of water engineering problems. The range of applications of entropy is constantly expanding and new areas finding a use for the theory are continually emerging. The applications of concepts and techniques vary across different subject areas and this book aims to relate them directly to practical problems of environmental and water engineering. The book presents and explains the Principle of Maximum Entropy (POME) and the Principle of Minimum Cross Entropy (POMCE) and their applications to different types of probability distributions. Spatial and inverse spatial entropy are important for urban planning and are presented with clarity. Maximum entropy spectral analysis and minimum cross entropy spectral analysis are powerful techniques for addressing a variety of problems faced by environmental and water scientists and engineers and are described here with illustrative examples. Giving a thorough introduction to the use of entropy to measure the unpredictability in environmental and water systems this book will add an essential statistical method to the toolkit of postgraduates, researchers and academic hydrologists, water resource managers, environmental scientists and engineers. It will also offer a valuable resource for professionals in the same areas, governmental organizations, private companies as well as students in earth sciences, civil and agricultural engineering, and agricultural and rangeland sciences. This book: Provides a thorough introduction to entropy for beginners and more experienced users Uses numerous examples to illustrate the applications of the theoretical principles Allows the reader to apply entropy theory to the solution of practical problems Assumes minimal existing mathematical knowledge Discusses the theory and its various aspects in both univariate and bivariate cases Covers newly expanding areas including neural networks from an entropy perspective and future developments.

This introduction to wavelet analysis 'from the ground level and up', and to wavelet-based statistical analysis of time series focuses on practical discrete time techniques, with detailed descriptions of the theory and algorithms needed to understand and implement the discrete wavelet transforms. Numerous examples illustrate the techniques on actual time series. The many embedded exercises - with complete solutions provided in the Appendix - allow readers to use the book for self-guided study. Additional exercises can be used in a classroom setting. A Web site offers access to the time series and wavelets used in the book, as well as information on accessing software in S-Plus and other languages. Students and researchers wishing to use wavelet methods to analyze time series will find this book essential.
