Extreme value analysis - Precipitation v2022 (Standard period)

Extreme value analysis - Precipitation v2022 (Standard period)Application

Return levels and return periods of precipitation over 10 minutes to 5 days. Observation period 1961-2020 for daily and multi-daily durations.
Maps of extreme precipitation

Maps of extreme precipitationApplication

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.
Extreme value analysis - Hyetograms

Extreme value analysis - HyetogramsApplication

Hyetographs (data) of the 10 (30) events with the highest cumulated precipitation over durations of 1, 4, 8, 12, 24 and 48 hours
Extrapolation for 2 and 5 minute precipitation

Extrapolation for 2 and 5 minute precipitationApplication

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