Skewed logistic distribution for statistical temperature post-processing in mountainous areas › A Skewed Working Paper!
This study shows the use and benefits of having a skewed response distribution rather than a symmetric one for ensemble post-processing of near surface temperature in Central Europe. A small adjustment which can strongly improve the predictive performance in alpine areas where the current ensemble forecast systems miss some of the wintery cold pools and overadiabatic heating of the valley atmosphere.

Hope being live in autumn! › Wetterturnier 2.0 Test Phase
For those grown up in a meteorological department in Innsbruck, Vienna, Zürich, Leipzig and Berlin the Wetterturnier should be well known. It is a platform where people challenge each other doing the best possible weather forecast for the upcoming weekend! As the existing system is getting old and buggy I've designed a new system over the last years (took quite a while!). However we are in the test phase right now! Read More ›

Parallelization with Python › Parallelization With Python
If you have a bunch of smaller jobs you have to go trough you might think of parallelization. While some software offers native parallel execution many do not. Python offers a very simple way to parallelize OpenMP jobs (no shared memory). An example. Read More ›
