was originally suggested by Páll Bergþórsson, former director of IMO, and Bo R. Döös in 1955. In addition to the analysis, the model also needs prediction of the development of weather at the boundaries of the domain, retrieved from a coarser resolution global NWP simulation from the European Centre for Medium-Range Weather Forecasts (ECMWF).

Simplest case: change in mean climate,
with no change in the magnitude of variability
If variability changes as well, the two tails of the distribution
(e.g., warm and cold) will be affected differently.
