Systematic errors in forecast near-surface air temperature (SAT) still constitute a considerable problem for numerical weather prediction (NWP) at high latitudes. Numerous studies in the past have attempted to reduce this problem through recalibratio

Huge computer resources needed to promptly compute the 24-h global weather forecast dictate the necessity to optimize the numerical algorithms of the model and their parallel implementation. We present some experience gained while implementing the ne
