Available in PDF, EPUB and Kindle. Book excerpt: Adjoint methods are used to examine the development of idealized and real extratropical cyclones. This research represents the first use of adjoint sensitivity that includes moist physical processes to study complete cyclone life cycles. Adjoint sensitivity is a computationally efficient technique for determining, in a comprehensive sense, the sensitivity of a forecast aspect (J) to small perturbations of model variables at earlier times in a numerical forecast, including initial conditions. In these simulations, J is selected to represent central pressure or vorticity of forecast cyclones. Specification of lower tropospheric (500-800 hPa) temperature and moisture near the incipient cyclone at the beginning of the storm track appears especially critical to cyclone prediction. Rapid cyclone intensification appears related to enhancement of dry baroclinic instability by latent heat release from nonconvective precipitation near the cyclone warn front. Cyclones can also be intensified by reduced surface stress and higher sea-surface temperature in the warm sector of the storm. The cyclone life cycle may be viewed in terms of an initially small- scale instability that propagates upward from a baroclinic zone in the lower troposphere, and leads to intensification of anomalies in both the upper and lower troposphere at the end of the storm track.

This book was released on 2013-12-10 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: High air pollution levels pose a significant threat to plants, animals and human beings. Efforts by researchers are directed towards keeping air pollution levels below well defined ‘critical‘ levels in order to maintain a sustainable atmosphere and environmental system. The application of advanced mathematical models is important for researchers to achieve this goal as efficiently as possible. Mathematical models can be used to predict answers to many important questions about the environment. This application comes with several complex theoretical and practical obstacles which need to be resolved. A successfully applicable mathematical model needs to enable researchers to • Mathematically describe all important physical and chemical processes. • Apply fast and sufficiently accurate numerical methods. • Ensure that the model runs efficiently on modern high speed computers. • Use high quality input data, both meteorological data and emission inventories, in the runs. • Verify the model results by comparing them with reliable measurements taken in different parts of the spatial domain of the model. • Carry out long series of sensitivity experiments to check the response of the model to changes of different key parameters. • Visualize and animate the output results in order to make them easily understandable even to non-specialists. This monograph thoroughly describes mathematical methods useful for various situations in environmental modeling - including finite difference methods, splitting methods, parallel computation, etc. - and provides a framework for resolving problems posed in relation to the points listed above. Chapters are written by well-known specialists making this book a handy reference for researchers, university teachers and students working and studying in the areas of air pollution, meteorology, applied mathematics and computer science.

Download or read book Operational Oceanography in the 21st Century written by Andreas Schiller and published by Springer Science & Business Media. This book was released on 2011-04-11 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade the significant advances in real-time ocean observing systems, ocean modelling, ocean data assimilation and super-computing has seen the development and implementation of operational ocean forecast systems of the global ocean. At the conclusion of the Global Ocean Data Assimilation Experiment (GODAE) in 2008 ocean analysis and forecasting services were being supported by 12 international centres. This book is about ocean forecasting - a maturing field which remains an active area of research, and includes such topics as ocean predictability, observing system design, high resolution ocean modelling and ocean data assimilation. It presents the introduction to ocean forecasting which provides a foundation for new opportunities in areas of coupled bio-geochemical forecasting and coupled atmosphere-wave-ocean forecasting. The book describes an updated account of research and development to improve forecast systems, determining how best to service the marine user community with forecast information as well as demonstrating impact to their applications. It also discusses operational centres that are now supporting a range of real-time ocean services including online graphical and data products for their user communities and their feedback on the quality of information. The contents of this book are aimed at early career scientists and professionals with an interest in operational oceanography and related ocean science. There are excellent opportunities for exciting careers in the emerging field of operational oceanography in order to address current and future challenges as well as provide the supporting services to a rapidly growing user community.
