If you are doing an RYA course or are simply seeking to gain a greater understanding of the weather, this edition of the RYA Weather Handbook (which covers the Northern and Southern Hemispheres) is full of practical and useful information, on aspects such as theory, weather charts, clouds, predicting the wind, and the technology used in sourcing meteorological information.

This edition provides more information than ever before about where to obtain forecasts, the growing use of technology in forecasting weather and obtaining up-to-date information and in particular monitoring the tell-tale signs around you for any indication that the weather may not be doing what was forecast.

The areas that have been substantially updated and enhanced with additional content are:

• Tropical weather (hurricanes, cyclones and sailing in the tropics)

• Climate change

• New technology

The illustrations have also been completely modernised and the look and feel of the layout has benefitted from an overall redesign, making even the most complicated subject easily understandable.
