The impact of Arctic sea‐ice loss on winter weather in the British Isles

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Arctic sea‐ice loss shifts the North Atlantic jet and storm track equatorward, and results in a more negative North Atlantic Oscillation and more positive East Atlantic and Scandinavian patterns. Strong extratropical cyclones weaken and become less frequent for the British Isles, but there is model disagreement for precipitation, surface winds, and ...

A study of a free convective boundary layer using a parcel‐based Lagrangian model

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We study the development of a convective boundary layer forced by surface heating and growing into a stably stratified atmosphere above. We compare our results with several recent comprehensive direct numerical simulation (DNS) studies and find broad agreement, and often close quantitative agreement, despite fundamental differences in the numerical ...

The benefits and challenges of using dense Mode‐S aircraft winds at ECMWF

Quarterly Journal of the Royal Meteorological Society, EarlyView.
In November 2022 ECMWF stopped using Mode‐S winds because their very high density in central Europe caused problems for the assimilation system. The data were reintroduced operationally in November 2023 combined with an improved aircraft thinning algorithm.

Continuum limit of the discrete nonlinear Klein-Gordon equation [PDF]

ESAIM: Proceedings and Surveys
We study the convergence of solutions of the discrete nonlinear Klein-Gordon equation on an infinite lattice in the continuum limit, using recent tools developed in the context of nonlinear discrete dispersive equations. Our approach relies in particular

Exploring strongly coupled land/atmosphere data assimilation for numerical weather prediction

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Soil moisture and soil temperature can be analyzed effectively in a numerical weather prediction system by expanding the atmospheric ensemble‐based data assimilation to update the soil states also. The best results were obtained here using a strongly coupled land/atmosphere data assimilation to assimilate the standard atmospheric observations plus ...

When tiny convective spread affects a midlatitude jet: Spread sequence

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We investigate spread evolution by mesoscale convection from tiny initial condition uncertainty during a real event. There is significant variation among the systems in their propensity to interact with the jet stream, whereby variability in one system (due to convective and long‐wave radiative heating tendencies) tightly relates to Rossby‐like ...

System Integration and Field Testing of Low‐Cost Autonomous Platooning Platforms: Collision Avoidance Scenario

Journal of Field Robotics, EarlyView.
ABSTRACT This paper presents the development and validation of a scalable platooning system based on the predecessor‐following (PF) topology, designed for low‐cost follower platforms. It integrates key technologies such as localization, path planning, profile generation, and low‐level control to create a practical solution.

A Unified Framework with Dynamic Kernel Learning for Bidirectional Feature Resampling in Remote Sensing Images

Remote Sensing
The inherent multiscale nature of objects poses a fundamental challenge in remote sensing object detection. To address this, feature pyramids have been widely adopted as a key architectural component.
