Climate change and circulation types in the Alpine region
Meteorologische Zeitschrift, 2017 The frequency of circulation types over the Alpine region is explored using 20 different global and regional climate model chains. The projected changes in these circulation types are investigated for the 21st century using the SRES A1B scenario.

An Ensemble Mean and Evaluation of Third Generation Global Climate Reanalysis Models
Atmosphere, 2018 We have produced a global ensemble mean of the four third-generation climate reanalysis models for the years 1981–2010. The reanalysis system models used in this study are National Centers for Environmental Prediction (NCEP) Climate Forecast System

Subgrid-Scale Topographic Effects on Radiation for Global Weather Forecast Models
AtmosphereThe incoming solar radiation arriving the Earth’s surface is strongly influenced by surface terrain. Conventional global weather forecast models, with grid scales of about 10 km, lack the resolution to accurately capture terrain-induced variations.
