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

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 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.
