Content
Ljubljana airport is located in the basin, surrounded by high mountains with peaks over 2500 m. The formation of radiation fog at the airport is therefore very common, especially in the wintertime. This greatly impacts the safety and effectiveness of aviation traffic.
The method used in Slovenia is based on statistical methods of interpreting observations and numerical weather prediction models output. In two methods, discriminant analysis and decision trees, they use three types of predictors - observations, MOS and PPM. They do not use the results directly but rather as a guide for the real forecast.
