An article by our colleague Jörg Burdanowitz has been published by Atmospheric Chemistry and Physics. The study reveals that extreme precipitation scaling over the ocean according to sea surface temperature depends on resolution. Along-track OceanRAIN ship data indicate a super Clausius-Clapeyron scaling above 8 % K-1 while the most recent ERA5 reanalysis scales with less than 5 % K-1. Unlike over land, no evidence was found for shorter precipitation events over higher sea surface temperature.
