Attribution of subseasonal cold‐spell forecasts to remote drivers using nudging experiments

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Nudging experiments with the European Centre for Medium‐Range Weather Forecasts (ECMWF) model show that Northern European cold spells can arise from different drivers. Some events are predominantly influenced by stratospheric dynamics, while others also involve important tropospheric processes.

Error in ERA5 2‐m temperature identified using GraphCast

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We identify a recurrent error in ERA5 2‐m temperature over the Ethiopian Highlands that occurs predominantly at 0600 UTC on ≈7%$$ \approx 7\% $$ of dates. The artefact is caused by the 2D optimal‐interpolation scheme assimilating temporally displaced surface reports (e.g., 0900 UTC) into the 0600 UTC analysis.

Response of the Intertropical Convergence Zone to Antarctic Ice Sheet Melt

Geophysical Research Letters, 2018
Past cooling events in the Northern Hemisphere have been shown to impact the location of the intertropical convergence zone (ITCZ) and therewith induce a southward shift of tropical precipitation.

Decadal‐scale drivers of South Pacific hydroclimate variability

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Using prescribed SST perturbations in the IGCM4 model, we investigate the mechanisms by which three major modes of low‐frequency climate variability—the IPO, AMV, and Southern Ocean SST‐driven midlatitude jet shifts—modulate the South Pacific hydroclimate.

Assessment of subseasonal forecast skill of tropical–extratropical cloud bands over the four subtropical convergence zones

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study evaluates the subseasonal predictive skill of tropical–extratropical cloud bands across four subtropical convergence zones in ECMWF reforecasts (2003–2022). Results show that, while exact daily predictions are limited to one week, accounting for temporal displacement improves forecast skill significantly, revealing a systematic early onset ...

Climate‐change‐amplified wind‐related economic losses during Cyclone Harry (2026)

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Cyclone Harry (January 2026) produced significant wind and rainfall impacts across southern Italy. Compared with 1950–1987, present conditions show warmer temperatures and stronger winds, increasing exposure. An estimated 72 million euros of damage are attributable to climate‐driven wind intensification. Abstract Cyclone Harry affected Sicily, Calabria,

A new objective technique for assessing global climate teleconnections

, 2018
Teleconnections are one of the main sources of intra-annual to inter-decadal variation in weather and climate and are one way that changes at the largest scales can be cascaded to adjustments at the smaller scales.
