Zusammenfassung
The global increase of global air temperatures since the Late-Glacial and during the Holocene is well-documented by means of proxy-data and meteorological monitoring. These model claculation show a more intensive global warming in high latitudes in comparison to the rest of the world. In relation to summer precipitation amount (May-September) an increase can be found for May ( 105%) and July ( 98%), while August (-65%) and September (-77%) follow high decreasing trends. While the number of precipitation events with middle and high amounts of rainfall decreased, the low-intensity precipitation increased during the summer period from 1978 to 2007. The evaluation of measuring data to strata specific interception results in very high losses in moss layer (55-60%). 17& of the precipitation sum were intercepted by the tree layer in both stands, while 4% were caught by shrub layer in VF Auf. Low amount of precipitation sum were held back by the dwarf layer (3-4%) in VF Auf, while one tenth of totally precipitation sum was intercepted by litter layer in both boreal stands. However, the seeping water entry varied from 8.5% in VF Auf to 5.2% in VF Alt.
