The atmosphere/flight environment is forever in a state of constant physical change, giving rise to weather conditions which vary throughout the range of an extremely large scale. The airman not only lives at the base of this sea of air, but navigates and flies through it. The weather, therefore, is a matter of vital concern to him, particularly conditions such as fog, ice formation, thunderstorms line squalls, all of which presents particularly unusual hazards to flying.
To minimize the hazards to air navigation that are constantly being manufactured in the so-called weather factory, a vast world-wide meteorological organization has been built up, to collect, analyze and broadcast information relative to the ever changing flight environment or the upper air.
The pilot can today avail himself of last minute weather reports and forecasts along all the regularly established air routes. In addition, he can secure much valuable weather data with reference to areas located off the organized airways. He must, however, possess sufficient and adequate weather sense, to be able to size up and deal with sudden changing conditions which may be encountered at any stage during flight. The brief notes which follow are intended to cover the highlights of the subject only. The student of aviation will be well advised to include meteorology among the subjects marked for further detailed study and read some of the excellent manuals which are available on the subject.
