Reeds Weather Handbook (2nd edition)/Справочник по погоде (2-е издание)

Издание на английском языке
Weather determines when we sail, where we sail to – and whether we arrive safely. This essential pocket-sized guide, now revised for its second edition, equips the reader with all the necessary tools to predict and deal with local and distant weather conditions, whether on a day trip or a longer cruise, along the coast or further offshore.
Each topic is broken down into digestible chapters, explaining the origins and effects of the full spectrum of weather conditions, including: using and evaluating weather forecastsdepressions, fronts, isobars and other coastal effects waves and swell weather lore and sky watching.
Meteorology is still advancing and sources of forecasts are changing. This new edition keeps the handbook up-to-date, with a particular focus on the increasing use of GRIB files, computer weather modelling and sources of forecasts, especially with the proliferation of computer forecasts becoming available free of charge.
With practical explanations and helpful diagrams and photographs, this is the ideal aide-memoire for skippers and crew, especially those studying for their Day Skipper and Yachtmaster exams.
