1. The CLAVIER project<br />
The CLAVIER project (Climate Change and Variability:<br />
Impact on Central and Eastern Europe) is supported by the<br />
European Commission's 6th Framework Programme as a 3<br />
year Specific Targeted Research Project from 2006 to 2009<br />
under the Thematic Sub-Priority "Global Change and<br />
Ecosystems". The CLAVIER consortium consists of 13<br />
partners from 6 countries, most of them coming from the<br />
CLAVIER target countries Hungary, Romania and Bulgaria.<br />
Based on a set of climate change simulations from different<br />
regional climate models, linkages between climate change<br />
and its impact on weather patterns, air pollution, extreme<br />
events, and on water resources are investigated.<br />
Furthermore, an evaluation of the economic impact on<br />
agriculture, tourism, energy supply and the public sector is<br />
conducted.<br />
Figure 1 shows the case study regions for economic impact<br />
assessment which have been defined based on the expert<br />
knowledge of the local CLAVIER partners.<br />

2. The CLAVIER model ensemble<br />
The CLAVIER model ensemble consists of three regional<br />
climate models, namely REMO from the Max Planck<br />
Institute for Meteorology (MPI-M) in Hamburg, used in<br />
Version 5.7 by MPI-M and REMO5.0 used by the<br />
Hungarian Meteorological Service in Budapest, and the<br />
LMDZ model developed at CNRS in Paris. From all models,<br />
A1B scenario simulations driven by the global climate<br />
model ECHAM5 are available for the period of 1950 to<br />
2050 with a horizontal resolution of about 25 to 30 km. For<br />
LMDZ, additional simulations driven by the IPSL global<br />
model are available for the A1B scenario.<br />
3. Interface climate simulations – impact<br />
studies<br />
One main challenge of conducting climate change impact<br />
assessment is the multidisciplinary knowledge which is<br />
needed. CLAVIER joins disciplines such as climate<br />
modelers, hydrologists, geographers, engineers and<br />
economists. To facilitate the communication and the data<br />
flow, an interfacing work package has been established<br />
which bridges the gap between the model simulation data<br />
and the needed input data for the impact studies. Among<br />
others, this work package is carrying out a bias correction<br />
procedure to account for the known biases of the regional<br />
climate models.<br />
4. Physical Impact Assessment<br />
The impact of climate change on different sectors has been<br />
studied. Among others, analyzes have been and will be<br />
carried out on: the water levels of the Lake Balaton, the<br />
hydrological regime of the Tisza river basin, possible<br />
changes in weather extremes, landslide and mud flow risks<br />
in the Sub-Carpathian regions, the risk of road damages in<br />
Hungary, and possible changes in typical weather regimes<br />
for Central and Eastern Europe and their implications to<br />
air pollution levels.<br />
5. Economic Impact Assessment<br />
The economic impact assessment concentrates on the four<br />
economic sectors with the highest expected impacts,<br />
agriculture, tourism, energy supply and the public sector.<br />
Based on the climate change information and on economic<br />
data for the respective sector (e.g. temperatures,<br />
precipitation from the climate simulations, sectoral<br />
economic data e.g. on tourism revenues, overnight stays,<br />
number and types of hotels, tourism infrastructure,<br />
restaurants, shops, beaches etc. for the tourism studies),<br />
the sensitivity and the exposure to a changing climate is<br />
assessed in 10 case study regions on the NUTS II and<br />
NUTS III level and finally translated into expected<br />
changes in regional macroeconomic indicators, such as the<br />
sectoral Climate Change impact on Gross Regional<br />
Product (GRP) allowing also for first estimates on the<br />
impact on Gross Domestic Product (GDP) on the national<br />
level respectively.<br />
This workshop contribution will give an overview on the<br />
results of the CLAVIER project.<br />
