English Abstract This report is the final report of the project
"Representation of the Seasonal Hydrological Cycle in climate and Weather
Prediction models in west Europe (NRP project 951246)". The report
describes the methodology used to unravel the influences of the land surface
on the atmosphere, in particular rainfall and temperature. 1-Dimensional
SVAT models are tested against observations and new parameterizations for
soil hydrology and canopy atmosphere exchange are developed and implemented
in the land surface model of a Regional Atmospheric Climate Model (RAMCO).
New maps of soil and vegetation properties are developed and used in
sensitivity studies. These studies show effects of these new parameters on
soil moisture storage and timing of evaporation. Europe-wide these
differences are small, but regionally they appear important. Also an
unexpectedly close relation between soil moisture, evaporation and rainfall
was found in the weather of Europe.
