The worldwide picked out as a central theme climate change and its results are very differently on the
regional level. The challenge concerning the development on the regional level of necessary adaptation
strategies and adaptation measures is accordingly high. To be able to estimate exactly possible climate
changes and from it arising problems, it requires the evaluation of the regional available climate data. By
means of the data being since 1965 to temperature, precipitation and global radiation a suitable climate
analysis was carried out in this work for the region Halle (Saale). By reason of the geographic position
in Middle Germany dry region there is a high vulnerability. For Germany and Saxony-Anhalt definite
noticeable climate changes were also proved for the region Halle (Saale) in the investigation period
1965 to 2008. The mean temperature increased by an average 1.3 K. Above all, the spring and winter
months showed a positive change of air temperature. The temperature developments also led to changes
in the appearance of extreme temperature incidents. The increase of the number of summer months
and hot days faces a decrease of frost and ice days. The mean precipitation sums show a not significant
trend of the increase. But, a clear rearrangement of the precipitation can be observed. Especially in
July and September an increase of the precipitation sum occurred. In June and August the precipitation
declined clearly. Furthermore, a slight increase of the winter precipitation is demoted. The shifting of
the precipitation maximum for July is mainly focused on a rise of the intense precipitation. These generally
increased in their intensity. The global radiation has increased after an at first negative trend since
the eighties. In all examined stations the upraised climate parameters showed similar developments.
Originally supposed differences between the stations Halle/Kröllwitz as a city station as well as Bad
Lauchstädt and Seeben as environs stations could not be confirmed. Probably city climatological effects
repeal by the distance to the city centre and the climatic positve favouring Dölauer Heide and Saaleaue
in immediate nearness. Regarding on the development of temperature extremes and intense precipitation
within the city, a consideration of the last ten years in all available stations seems reasonable. Especially
because of the very probably increasing air temperatures (IPCC, in 2007) the number of the summery
extreme incidents increases. This would have direct consequences on the quality of life of the people
living in the city.
Key words: climate change, climate data, air temperature, precipitation, global radiation, climate of
