Examples of use: compare stations or classify observed events. Use this approach when more than one point in space or time is of interest. Periods of analysis: 1961 - 2020 (daily sums): updates every 10 years / 1981 onwards (min./hourly sums): yearly updates

Examples of use: single, local design. Use this approach in the context of specific, spatially and temporally confined applications. Period of analysis: From the earliest measurements onwards: yearly updates.

Hyetographs of the 10 events with the highest cumulated precipitation over duration intervals of 1, 4, 8, 12, 24 and 48 hours.

The following maps depict precipitation amounts for extreme events. The spatially comprehensive representation describes the climate of heavy precipitation in Switzerland and its immediate surroundings, and illustrates contrasts between regions and seasons. The maps constitute an important knowledge base for the protection against natural hazards.

Return levels of 2 and 5 minute precipitation sums extrapolated from the extreme value analysis of 10 minute precipitation sums.
