The sea breeze affects our lives in many ways. It controls our local weather, not only on the coast but also in many districts inland. Air pollution and smog, also the distribution of airborne insect pests and the spread of pollen are all controlled by the sea breeze. In the world of sport it is important to glider pilots, sailors and surfers, and balloonists. In the book we see how radar, lidar and satellite photography have helped to forecast and map sea breezes and the all-important 'sea-breeze front'. The book ends with a description of laboratory experiments mostly carried out by the author and his co-workers, and a simple summary of theoretical models. The book will be welcomed by those researching in the subject but will also be valuable to the general reader who is interested in local weather and the natural environment.

This 1997 book comprehensively describes all aspects of gravity flow, a physical process in the environment that is covered by many different disciplines, including meteorology, oceanography, the earth sciences and many industrial processes. No other book covers a similar range of information. This second edition includes much new material, and, like the first edition, the hardback has been very well received. Gravity currents are described with a variety of laboratory experiments, many from the author's own work. Now in paperback, Gravity Currents is a valuable supplementary textbook for undergraduates and a reference work for research workers. The general reader will also find much of interest, since the physics of the flows involved is clearly described, without advanced mathematics, by numerous photographs and illustrations.

Referring to specific information inside an XML document is a little like finding a needle in a haystack: how do you differentiate the information you need from everything else? XPath and XPointer are two closely related languages that play a key role in XML processing by allowing developers to find these needles and manipulate embedded information. XPath describes a route for finding specific items by defining a path through the hierarchy of an XML document, abstracting only the information that's relevant for identifying the data. XPointer extends XPath to identify more complex parts of documents. The two technologies are critical for developers seeking needles in haystacks in various types of processing. XPath and XPointer fills an essential need for XML developers by focusing directly on a critical topic that has been covered only briefly. Written by John Simpson, an author with considerable XML experience, the book offers practical knowledge of the two languages that underpin XML, XSLT and XLink. XPath and XPointer cuts through basic theory and provides real-world examples that you can use right away.Written for XML and XSLT developers and anyone else who needs to address information in XML documents, the book assumes a working knowledge of XML and XSLT. It begins with an introduction to XPath basics. You'll learn about location steps and paths, XPath functions and numeric operators. Once you've covered XPath in depth, you'll move on to XPointer--its background, syntax, and forms of addressing. By the time you've finished the book, you'll know how to construct a full XPointer (one that uses an XPath location path to address document content) and completely understand both the XPath and XPointer features it uses. XPath and XPointer contains material on the forthcoming XPath 2.0 spec and EXSLT extensions, as well as versions 1.0 of both XPath and XPointer. A succinct but thorough hands-on guide, no other book on the market provides comprehensive information on these two key XML technologies in one place.
