In this paper, we present two micro rain radar-based approaches to discriminate between stratiform and convective precipitation. One is based on probability density functions (PDFs) in combination with a confidence function and the other one is an ar

Temporal changes in daily precipitation observed at more than 2300 stations in Germany during the second half of the 20th century are analysed. Compared to other studies, this analysis is based on a very high spatial density of observation locations

Publikováno v: CIRED 2012 Workshop: Integration of Renewables into the Distribution Grid.

The rapid growth of renewable energies is leading to increasing imbalances between electricity production and consumption. During high-wind periods with local overproduction of energy, the stability of the distribution grid can only be ensured if a f

The link between trends in circulation patterns and trends in the flood magnitude is studied for 122 meso-scale catchments in Germany for a period of 52 years (1951–2002). Flood trends, significant at the 10% level, are detected for a large number
