A Skewed Working Paper!

Skewed logistic distribution for statistical temperature post-processing in mountainous areas

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.
