How to build the statistical model
• Transfer functions: quantify relationship between large-scale
climate (predictor) and local variables (predictand) by
e.g. regression. Most often used for monthly temperature and
precipitation.
Related to Perfect Prognosis (PP) and Model Output Statistic
(MOS) in numerical weather prediction.
• Weather typing: relate a particular atmospheric state
to a set of local climate variables
(Lamb weather typing, Grosswetterlagen, others..)
• Weather generators: generate realistic looking sequences
of e.g. daily precipitation based on the large-scale
atmospheric state
