MAWECLI – MArine and WEather events in the changing CLImate as potential external hazards to nuclear safety
MAWECLI (MArine and WEather events in the changing CLImate as potential external hazards to nuclear safety) aims to increase preparedness towards single and compound marine and atmospheric extreme events that may pose external hazards at nuclear power plant level. The project strives to enhance methods on physical and statistical modelling, extreme value analysis and uncertainty quantification by joining expertise of scientists from various disciplines.
MAWECLI project studies marine and atmospheric extreme events to support nuclear power plant safety in Finland. The photo shows arcus clouds on the leading edge of thunderstorms near the southern coast of Finland on 23 June 2021. Photo: Lassi Karvonen.
The project outcomes include improved estimates on coastal flooding risks, extreme air temperature, and worst-case flooding events caused by cyclones. We also produce estimates of the frequency and magnitude of high wind gusts, impacts of climate change on sea-effect snowfall, and joint effect of intense snowfall and high wind speeds, and make multi-hazard assessment for convective storms, meteotsunamis and lightning.
