Short Discription

Ø  Snow Hydrology requires spatial resolution of 0.1 km

Ø  The most advanced regional climate data set available for Europe is from the EURO-CORDEX project with spatial resolution of 12 km

Ø  There is a Substantial gap between the available and the necessary spatial resolution of the meteorological information.

Downscaling

Ø  Downscaling is a procedure to take information known at

large scales to make predictions at local scales. i) Dynamical Downscaling ii) Statistical Downscaling

Ø  Dynamical Downscaling è Out of reach!

Ø  In the case of snow hydrology - usually a statistical downscaling approach is required.

Seite 5

Ø  A weather generator is a statistical model used to generate realistic daily sequences of weather variables — precipitation, maximum and minimum temperature, humidity, etc.

Ø  WG will be used to derive future climatological states to be used in snow-hydrological application for the Alpine region.
