This project will investigate co-occurring extreme wintertime events of low temperature over North America and wind and precipitation over Europe (hereafter pan-Atlantic extremes) using CMIP6 models. Individually, these extreme events can cause sever disruption, loss of life and damage to infrastructure costing billions of Euros. When these events occur simultaneously, they can often result in larger impacts than the sum of their individual components. Previous work using reanalysis data has established a statistical and dynamical relationship for pan-Atlantic extremes. This work also established a regional dendency between the location of the low temerature extremes and the type, timing and location of extremes experienced by Europe. We will determine how well these links are represented in CMIP6 models compared to reanalysis. This project aims to open the door to improvements in the predictability of pan-Atlantic extremes and the investigation of how pan-Atlantic extreme occurrences will vary due to climate change.
