Intended for pilots of light aircraft, sailplanes, hang gliders, microlights and balloons, this detailed book on meteorology explains the benefits and hazards of atmospheric phenomena. The author describes the influence of high-level jet streams on the development of depressions, as well as detailing thermals, lee waves and up-and-down currents which are important to pilots of sailplanes, microlights, hang gliders and balloons. Diagrams show the movement of air at various heights and also trace the development of clouds, from fair weather cumulus to giant cumulonimbus and the associated hazards of lightning, hail, downbursts and outflows. In addition there are sections on how to obtain weather data and satellite information and notes on computer forecast. Tom Bradbury trained on light civil aircraft after the war and won the Diamond C badge in gliding. He served in the British Meteorological Office for over 40 years and has acted as forecaster at many gliding contests.
