Guidelines

1) Study the existing methods for analytical computation of such weather alarms from available weather data. Choose phenomenon from the list to focus on.
2) Propose the mathematical solution to such problem.
3) Design and implement algorithm(s) the solution using the NetCDF library in Python and other available libraries needed for such computation.
4) Integrate the algorithmic solution to an existing weather processing pipeline providing connection to visualization tools for the pilots.
5) Scale-up the solution to provide the required scale in volume and speed of computation needed by the real deployment (order of minutes for one computation every 15 minutes)
6) Experimentally verify that the method works good enough for practical usage by the pilots.

Preliminary scope of work in English

The most important phenomenon like that are icing, CAT, CIT and hail. Such phenomenon does not need to be necessarily predicted and localized precisely in the atmosphere, but for practical use only rough location of such phenomenon must be predicted and visualized to the pilots as icons. Such functionality is currently provided by systems like Meteoalarm [1], however not in 3D and for different weather phenomenon. The computation must be fast enough to be usable for the pilots in real-time, technically limiting the computation to order of minutes. The volume of interest is the area of Europe from the ground to approximately 45000ft (~13km) height for 5 hours window to the future. Prediction of each of mentioned phenomenon requires a substantial amount of work, therefore the student can choose and focus only on one of the mentioned phenomenon.
