ExtremesModel runs show the 2023 North Atlantic marine heatwave could have been far worse
In a climate model, starting conditions like those of the 2023 North Atlantic marine heatwave can evolve into events much longer and hotter than the observed one.

ExtremesEvent-scale checks show WRF-HAILCAST reproduces hail swaths in about half of 1,502 events
When hail is judged at the scale of whole storm events rather than single cells, WRF-HAILCAST matches observed hail swaths in 50.87% of events, and most errors trace to storm placement, storm core development and hail growth rather than to CAPE or shear.

ExtremesMulti-GPU model simulates a Berlin-wide flood at 5 m resolution in 34 minutes
With eight GPUs, the RIM2D flood model can simulate a 48-hour rainstorm over all of Berlin fast enough for early warning, at 10 m, 5 m and even 2 m resolution.
