For years hillwalkers and climbers have struggled to understand the complexities of weather systems. Written by a professional weather forecaster, Weather for Hillwalkers provides invaluable insight to the beginner and veteran alike. Now in a new edition, Malcolm Thomas offers an understanding of the principles of the elements - the causes of wind, rain, snow, cloud, fog, thunder and clear skies - and looks at how they are affected by mountains and high ground. Readers will learn the terminology of depressions, warm and cold fronts, air masses and more; how to interpret weather maps; and how to make short-term weather forecasts from observations. This is essential reading for those tackling the elements amongst the hills.
