Research Topic Multi-site Weather Generator for complex-terrain applications in snow hydrology
Seite 3
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.
