This new third edition of 'Meteorology for Pilots' has been modified to satisfy all aspects of the meteorological requirements necessary to be JAR compliant. It also discusses the latest data concerning global warming and its consequences, especially in relation to the El Nino effect.For aviation the study of meterology provides knowledge and awareness of the atmosphere, which is, after all, the medium within which the pilot works. A proper study of the subject will provide the basis that can enable a pilot to appreciate properly the weather forecast given to him for a flight - and indeed to forecast for himself. Technical aircraft safety is now approaching the highest standards, whilst safety affected by particular weather conditions remains a large problem.Clearly a proper study of meteorology can only assist the pilot in providing safe passage.
