Forecasting For Soaring Flight -wmo- Technical Note No. 203- - Weather

For current operational use, one should combine the physical principles of TN 203 with modern NWP output, but the mental framework — especially the separation of lift mechanisms and the emphasis on the convective boundary layer — is timeless. If you need a specific extract, figure description, or comparison with modern soaring forecast guidelines, let me know.

1. Context and Purpose Published in the early 1980s (though still a foundational reference in meteorological education for soaring), Technical Note No. 203 was produced by a working group of the WMO Commission for Aeronautical Meteorology. Its primary goal was to provide operational meteorologists and soaring pilots with a systematic framework for forecasting mesoscale and local conditions critical to unpowered flight. For current operational use, one should combine the
