The essential parts of the project are the global and regional climate model integrations focusing on Central Europe in the 18th-20th centuries and their comparison to temperature and precipitation series reconstructed from instrumental measurements, documentary evidence and natural proxy data. The project research will address following questions:
How reliably can the climate of the 18th-19th centuries be reconstructed from existing measurements and proxies?
Can the confrontation of past climate model simulations and time series reconstructed from observed data help to improve models? And in case of a positive answer in which aspects and to what extent?
To which extent are regional and global climate models capable to reproduce temporal and spatial variability of hydrometeorological extremes?
To which extent is it possible to use the ensemble of simulations to fill in the missing values in time series of natural proxies or documentary data?
What is the capability of the GCM and RCM to reproduce low and high frequency variability of temperature and precipitation series in Central Europe?
What are differences in manifestations of natural and anthropogenic climate-forming factors in model outputs and temperature and precipitation (reconstructed and measured) data?
Models utilized at CHMI in the frame of project are:
Global Climate Model CNRM-CM5
developed at GMGEC Department of Centre National de Recherches Météorologiques/Météo-France (model ARPEGE as an atmospheric component, model NEMO as an ocean compoment, model TRIP as a river system component, model GELATO as a sea ice model and SURFEX as amodule describing atmosphere interaction with Earth’s surface) 2. Regional Climate Model ALARO-Climate as developed at Czech Hydrometeorological Institute in frame of ALADIN consortium.
