Assessing the Performance of the Copernicus European Regional Reanalysis Dataset in Reproducing Extreme Weather Events in Poland

International Journal of Climatology, EarlyView.
Global reanalyses, for example ERA5 and ERA5‐Land, tend to misrepresent the local‐scale weather extremes due to the limited spatial resolution. In this paper CERRA shows clear and consistent improvements over ERA5 and ERA5‐Land in representing extreme temperature and precipitation in Poland, particularly for localized and short‐lived heavy rainfall ...

Observed Linkages Between Marine Heatwaves and Extreme Weather Over Land: A New Zealand Case Study

International Journal of Climatology, EarlyView.
Marine heatwaves consistently warm New Zealand's land surface, but rainfall impacts occur only when synoptic systems enable moisture transport. This 38‐year analysis shows MHWs act as thermodynamic background drivers of heat and conditional amplifiers of extreme rainfall events or droughts.
