| Zusammenfassung |
| Lake Neusiedl (Neusiedler See, FertÅ tó) is a very shallow steppe lake (area 320 km2, mean
depth 1.2 m) at the border of Austria/Hungary. The low ratio of water depth to water
volume accounts for dynamic, air temperature-dependent developments of water
temperature with the potential of unusually warm waters that are a pillar of the touristic
attractiveness of the lake. Likewise these conditions are a risk factor for water quality
deterioration.
In the frame of the EULAKES-project (European Lakes under Environmental Stressors,
www.eulakes.eu), financed by the Central Europe Programme of the EU, data records of
water temperature at 5 monitoring stations of Lake Neusiedl (eHYD) and the nearby air
temperature monitoring station Eisenstadt - Sopron (HISTALP database and ZAMG) were
used to investigate the period 1976-2009. Additionally the influences of 7 teleconnection
patterns, i.e. the East Atlantic pattern (EAP), the East Atlantic/West Russia pattern (EA/WR),
the Eastern Mediterranean Pattern (EMP), the Mediterranean Oscillation (MO) for Algiers
and Cairo, and for Israel and Gibraltar, resp., the North Atlantic Oscillation (NAO) and the
Scandinavia pattern (SCA) were assessed.
The increase of temperature during the observation period was more pronounced for water
than for air. Water temperatures increased significantly (p |
