Weather has a daily impact on our lives. The elements of heat, cold, wind, rain, snow and hail control much of our behaviour. David Ellyard investigates this force and shows the reader how to predict the weather in the southern hemisphere with simple devices and discusses how technology has advanced through the ages to harness patterns for power. He also explains the causes of the Greenhouse effect and takes case studies of weather patterns in southern hemisphere land masses such as Australia, New Zealand, South Africa, South America and Antarctica.
