This case study focuses on making a forecast and writing a TAF so that it best represents the meteorological situation to aviation customers. During the exercise, the student prepares a forecast for Sioux Falls, South Dakota. As part of the Distance Learning Aviation Course 1 (DLAC1) on Fog and Stratus Forecasting, the exercise applies concepts taught in the rest of the course, with special emphasis on determining the impacts on airfield flight operations and creating a TAF that describes those impacts. The module is a re-creation of several live teletraining sessions offered in 2003 as part of DLAC1.
• Use model analyses, forecast products, soundings, and climatology to write a customer-friendly TAF
• Evaluate the impacts of forecasted ceiling and visibility conditions on the airfield operations
• Verify the accuracy and usefulness of your TAF
July 2014: This lesson includes references to the Eta numerical weather prediction model no longer in operational use. The presentation of satellite products is similarly dated and does not include newer capabilities for fog and low cloud detection available with the current generation of geostationary and polar-orbiting weather satellites becoming available since the 2004 publish date.
