Title Connecting large scale atmospheric circulation structures and local extremes
Period 03 / 2006 - 09 / 2007
Status Completed
Research number OND1318822

Abstract

Local weather extremes, like extreme low or high temperatures, extreme precipitation events, droughts, are not just caused by local conditions; a dominant influence is exerted by the large scale atmospheric flow. In this project we develop a statistical method to describe this influence in an optimal way. Observed meteorological timeseries are analysed. Results from climate model integrations are validated against the observations. This technique can be applied to future scenario simulations to better evaluate possible changes in the probability of local extremes in a future climate.

Abstract (NL)

Lokale weerextremen, zoals extreem lage of hoge temperaturen, extreme neerslag, extreme droogte, komen niet uit de lucht vallen; er is een duidelijk verband met de toestand van de grootschalige atmosferische circulatie. In dit projekt ontwikkelen we een statistische methode om dit verband uit waargenomen en gesimuleerde tijdreeksen optimaal te destilleren. Deze techniek kan vervolgens gebruikt worden om de simulaties te valideren en veranderingen in toekomstige extremen uit scenario simulaties beter in te schatten.
