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.

Using microwave imager observations to improve the ocean temperature in a coupled NWP system

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A recent upgrade to the ECMWF IFS has implemented outer‐loop coupling between the atmosphere and the ocean. This work uses this method to pass ocean skin temperature estimates derived from satellite‐borne microwave imagers to the ocean data assimilation system; the updated ocean state is then passed back to the atmospheric system.

Dry intrusions and warm‐core development in Medicanes: Insights from a multi‐case analysis and the peculiar evolution of Ianos

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Mediterranean tropical‐like cyclones show a clear seasonality, with September cyclones exhibiting the deepest convection and Ianos representing the most extreme case. While one or more dry intrusions are typically detected during the cyclone life cycle, Ianos instead features two much weaker descending airflows.

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 ...

Multiscale numerical sensitivity simulations of a mesoscale gravity‐wave event

Quarterly Journal of the Royal Meteorological Society, EarlyView.
High‐resolution WRF simulations of the February 14–15, 1992 STORM‐FEST event show that mesoscale gravity‐wave genesis occurs via geostrophic adjustment within an upper‐level unbalanced jet, while wave ducting governs maintenance. High‐resolution (1 km), improved physical parameterization, and targeted sensitivity simulations demonstrate that upstream ...

Impact of fragmented urbanization on observed precipitation

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study investigates the impact of fragmented urban landscapes on downwind precipitation by applying an innovative observation‐centered approach to an extensive rain gauge network in Belgium. The approach classifies the observations based on the upwind urban land cover fraction, and compares precipitation indices between rural‐ and urban‐labeled ...

Evaluation and assimilation of Arctic Weather Satellite data in the AROME‐Arctic forecast system

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The Arctic Weather Satellite (AWS), launched in August 2024, is a prototype for the future EPS–Sterna constellation of small satellites carrying an innovative microwave sounder. We present the first assessment of AWS in the regional AROME‐Arctic numerical weather prediction system, covering post‐launch calibration results and the impact of AWS ...
