Bad weather can play havoc with the best-laid plans. This is especially true in air traffic management, where poor meteorological conditions are the cause of an estimated 20% of all traffic delays in Europe. Performing better during adverse weather relies on timely and accurate forecasts, which is easier said than done given how quickly the conditions can evolve. Closing the gap on the uncertainty brought about by weather has been a focus of a number of SESAR research and innovation projects over the last two years.
INTEGRATING METEOROLOGICAL UNCERTAINTY INTO FLOW MANAGEMENT
Adverse weather has a significant impact on air traffic. It is estimated that poor meteorological conditions en-route are responsible for about 4 million minutes of delay every year in Europe. Delays come about because bad weather makes air traffic difficult to predict and complex to manage, resulting in reduced airspace capacity. “It is quite challenging, mainly because forecasting adverse weather is very difficult, even for short lead times. Furthermore, the accuracy of the weather prediction rapidly degrades with the forecasting horizon. Quantifying the weather forecast uncertainty is the main
