Book Description
Many numerical model verification systems are handicapped by their inability to separate random errors, defined as scales of motion smaller than the concerned scale, and systematic errors. Random errors may be eliminated by time averaging over a minimum allowable data period. Statistical methods are implemented to determine a minimum data period needed to constitute a time scale within which numerical forecasts errors are truly systematic and not smoothed fields of rapidly varying random errors for a synoptic scale event. Long term or model climatological error patterns of a specific event are compared with randomly determined shorter term error patterns through statistical tests and measures to provide results which indicate a minimum case number needed to sufficiently smooth out unwanted random errors.

Book Description
This textbook provides a comprehensive yet accessible treatment of weather and climate prediction, for graduate students, researchers and professionals. It teaches the strengths, weaknesses and best practices for the use of atmospheric models. It is ideal for the many scientists who use such models across a wide variety of applications. The book describes the different numerical methods, data assimilation, ensemble methods, predictability, land-surface modeling, climate modeling and downscaling, computational fluid-dynamics models, experimental designs in model-based research, verification methods, operational prediction, and special applications such as air-quality modeling and flood prediction. This volume will satisfy everyone who needs to know about atmospheric modeling for use in research or operations. It is ideal both as a textbook for a course on weather and climate prediction and as a reference text for researchers and professionals from a range of backgrounds: atmospheric science, meteorology, climatology, environmental science, geography, and geophysical fluid mechanics/dynamics.

Book Description
Climate Systems Modeling presents an interdisciplinary and comprehensive study of the dynamics of the whole global system. As a comprehensive text it will appeal to students and researchers concerned with any aspect of climatology and the study of related topics in the broad earth and environmental sciences.

Book Description
This book articulates why services from national meteorological and hydrological services (NMHSs) are important to improve nations' weather and climate resilience. It provides a baseline vision for improving NMHSs, identifies obstacles, and recommends World Bank strategies.

Book Description
Now in paperback, this book has succeeded in its aim to introduce the global climate problem and the complex processes and interactions which play a part in climatic change to a wide range of scientists working in climatic research or the related fields of meteorology, oceanography, glaciology and hydrology. It is centred around the World Climate Research Programme, an international enterprise jointly sponsored by the scientific community (through the International Council of Scientific Unions) and the national weather centres (through the World Meteorological Organisation). If progress is to be made in understanding climatic change, it is necessary to observe and understand all components of the climate system and the interactions between them. This book is particularly relevant to many contemporary climatic problems and to the two most important questions arising tom them: to what extent can changes in climate be predicted; and what is the extent of man's influence on climate. The Global Climate answers these questions, showing how the important processes may be -observed, evaluated and modelled by computer.

Book Description
This study systematically investigates the representation of warm conveyor belts (WCBs) in large reforecast data sets of different numerical weather prediction models and evaluates the role of WCBs for the onset and life cycle of Atlantic-European weather regimes. The results emphasize the importance of accurate forecast of WCBs for sub-seasonal prediction on time scales beyond two weeks and tie the low forecast skill of blocked weather regimes over Europe to misrepresented WCBs.
