Don utilizes “analog forecast” principles which are more weighted to past observed weather events/patterns as opposed to computer modelling. Day believes the key to accurate long-range forecasts are combination of identifying past weather patterns and comparing those patterns forecast by modern computer modelling. Day also specializes in weather forecasting and analysis for stratospheric aviation with emphasis on lighter than air vehicles (stratospheric balloons, airships, and very high-altitude experiments). He was the chief meteorologist for Felix Baumgartner’s record and groundbreaking Red Bull Stratos Stratospheric sky dive in 2012 and for Google’s Alan Eustace stratospheric jump in 2014 (Stratex).
