Heavy Weather Avoidance Concepts And Applications Of 500 Mb Charts

In Heavy Weather Avoidance, Chen and Chesneau merge the seamanship of a master mariner and the forecast expertise of a senior meteorologist, providing readers with double-barrel exposure to what actually goes on in the atmosphere and on the sea's surface. Mariners and recreational sailors are more concerned about the implications of volatile weather rather than its fluid dynamics. From start to finish the authors have cut to the chase, creating a readable text brimming with useful graphics. It's focused on the root cause of how and why bad weather develops and where it's likely to go. There's enough theory provided for a reader to get a feel for how air mass energy transfer works, but just as the theoretical aspect takes on a mission of its own, there's a shift to more practical self-forecasting and storm avoidance wisdom. Captain Ma-Li Chen shares his well-tested routing strategy and describes how it factors in the use of the 500 Mb chart.

Since writing the previous edition of Storm Tactics Handbook, Lin and Larry have voyaged an additional 55,000 miles. This has taken them as far north as Norway, twice across the Atlantic, south to Argentina and into the Pacific, around Cape Horn contrary to the prevailing winds then on a North Pacfic circuit. With insights gained from these recent voyages, they have fully revised and expanded this text by more than 40% including seven completely new chapters – among them;

Lessons from Cape Horn,

An interview on storm survival and heaving to with the late Sir Peter Blake,

Heaving-to using a Gale Rider on 55 foot Morgan’s Cloud,

Adding Rudder Protection Stops.

Discussions on avoiding chafe, building and using storm staysails, choosing storm gear, when to deploy para-anchors, tactics for avoiding the worst areas of cyclonic storms and many more have been expanded to answer questions posed by readers and seminar attendees.

Originally published in 1975, Voyaging Under Power created a revolution in small-boat cruising. Until then, essentially all long-distance cruising was done in sailboats because there simply were no production powerboats capable of crossing oceans. Author Robert Beebes book showed for the first time how to cruise under power, covering boat design, engine selection, outfitting, and operations. The result was the birth of a new market, served by a whole new industry of power cruiser designers, builders, equipment manufacturers, and magazines.

Whether you are a weekend sailor, an experienced yachtsman, or a professional mariner, you will find this book to be an indispensable guide to coping with storms at sea.

Weather Map Handbook is a guidebook and encyclopedia of the most common weather forecasting charts used in operational forecasting in the 2010s. It's written by a veteran forecaster for forecasters. All of the products are available on centralized systems like AWIPS and on the Internet on servers run by central weather agencies. Using a double-page format, the Weather Map Handbook demonstrates nearly every type of weather map, image, and product in common use. An overview of each item's origin, purpose, shortfalls, and tips are outlined. Standards for analysis symbology and chart markings are summarized. The surface, 850 mb, 700 mb, 500 mb, and 300-200 mb charts get two pages each, complete with philosophy, objectives, and techniques for each chart. Thickness, isentropic, and Q vector products get their own sections. The WSR-88D doppler radar, in use by the United States weather services, has played a vast part in the weather information revolution. In the Weather Map Handbook, it gets an entire section ranging from reflectivity, velocity, and spectrum width to dual-polarization products. Some of the details provided in this book are obscure and nearly impossible to find. From the workings of the Composite Reflectivity product to the exact process used by the Mesocyclone Detection Algorithm to deconstruct a radar scan, any NEXRAD radar product on the Internet can be understood. From the NAM to the HRRR, from the GFS to the ECMWF, forecasters get grounded in the history and configuration of numerical forecast model. Ensemble forecasts are highlighted. The satellite chapter explains visible, infrared, and water vapor imagery, how it's created, and how to interpret it. Even the METAR, TAF, SYNOP, and radiosonde formats get their own sections, complete with decoding instructions. Whether you're a hobbyist, private forecaster, a professional, or a student, the Weather Map Handbook is the book you can't be without.
