Impact of Weak‐Constraint Four‐Dimensional Variational data assimilation on the prediction of a sudden stratospheric warming event in 2024

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The Weak‐Constraint Four‐Dimensional Variational (WC‐4DVAR) system markedly improved the analysis and forecasting of the 2024 sudden stratospheric warming (SSW) event. It reduced biases and enhanced 7–9 day predictions of temperature across the SSW life cycle, with the most pronounced gains for winds also during the critical onset period.

Scale dependence of the marine atmospheric boundary‐layer response to ocean surface‐temperature variability in the EUREC4$$ {\mathrm{EUREC}}^4 $$A region

Quarterly Journal of the Royal Meteorological Society, EarlyView.
With a minimal physics model and a high‐resolution fully 3D simulation, we demonstrate that the marine atmospheric boundary layer (MABL) response to sea‐surface temperature (SST) variability displays a dependence on the horizontal scales of motion.

Characterization and Variability of Extratropical Cyclones in the Southwest Atlantic Ocean

Advances in Meteorology
Extratropical cyclones are key features that contribute to changes in precipitation, wind, and temperature at midlatitudes, sometimes causing extreme conditions. Despite the southwest Atlantic Ocean being recognized for cyclone formation and intensification, several aspects of spatial and temporal variability remain unclear.

The physical and synoptic‐dynamical differences between warm days, hot days, and heatwaves during summer in Victoria, Australia

Quarterly Journal of the Royal Meteorological Society, EarlyView.
During the day, there is composite mean cold advection in the boundary layer on warm days (WDs), hot days (HDs) and heatwaves (HWs). There is weaker surface‐sensible heating on HDs and HWs. A nocturnal jet advects warm air on HDs and HWs. There is a strong and slow‐moving upper‐level anticyclone on HWs.

North American “warming holes” and European heat during abrupt Holocene cooling events in the Atlantic

Nature Communications
In recent decades, Europe has warmed rapidly while a prominent ‘warming hole’ has muted changes in eastern North America. Paradoxically, the pattern coincides with cooling in the North Atlantic, even though ocean cooling is commonly expected to chill ...

Evolution of sea fog based on meteorological and oceanographic observations during FATIMA Yellow Sea campaign

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study presents a conceptual framework linking sea‐water temperature Tw gradients to the formation and persistence of sea fog in the southeastern Yellow Sea. Over cold waters maintained by tidal mixing, downward latent heat flux enhances lower‐level stability and sustains persistent sea fog, whereas over warmer waters, upward fluxes and thermal ...

Structural changes in the interannual variability of extreme autumn precipitation in eastern Spain and the weakening of synoptic forcing

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Total autumn precipitation in eastern Spain remains stable between 1950 and 2024, masking a substantial internal redistribution between ordinary and extreme rainfall. While torrential precipitation (Rp95) increases and ordinary precipitation (Ro) decreases, the extreme contribution index (Cext) shows a significant positive trend and a structural shift ...
