Further development of adaptive parameter tuning in the numerical weather prediction models of Deutscher Wetterdienst

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The introduction of adaptive parameter tuning in the numerical weather prediction models of DWD in 2022 substantially improved the forecast quality of near‐surface variables like 2‐m temperature and 2‐m humidity. Since 2023, refinements and extensions, primarily affecting the surface evaporation and its diurnal cycle, have led to further advances ...

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 ...

Why does typhoon Noru (2022) possess severe rapid intensification as explored by the extended Sawyer–Eliassen equation?

Quarterly Journal of the Royal Meteorological Society, EarlyView.
As inferred from the Sawyer–Eliassen analyses, the intense diabatic heating located slightly inside the radius of maximum tangential wind (RMW) associated with a compact eyewall is mainly responsible for the severe RI of Noru, in contrast to typhoon Goni (2020) at a slower spinup despite similar RMW, due to the weaker diabatic heating. The severe RI of

Subseasonal forecasts of the MJO and convectively coupled equatorial waves in ACCESS‐S2 and GraphCast: A multi‐year analysis

Quarterly Journal of the Royal Meteorological Society, EarlyView.
ACCESS‐S2 performs better in predicting longer time‐scale and slower moving waves (MJO and equatorial Rossby waves), while GraphCast performs better in predicting shorter and faster moving waves (Kelvin and mixed Rossby–gravity waves). However, both models systematically underestimate precipitation amplitude across all wave types, especially over the ...

Multivalent Bi‐Specific Nanoerythrosomes: A Two‐Birds‐One‐Stone Approach to Combine Homologous and Active Targeting for Effective Thrombolysis

Small, EarlyView.
A multivalent bi‐specific nanoerythrosome (mBiNE@tPA) is developed as a “two‐birds‐one‐stone” platform that simultaneously exploits two principal thrombus components. By integrating erythrocyte membrane‐mediated homologous targeting with cRGD‐based active targeting to activated platelets, mBiNE@tPA achieves enhanced thrombus accumulation, triggered ...

Climate‐Modulated Particle Toxicity: Acute Exposure to an Environmentally Informed Microplastic Mixture Induces Sex‐Dependent Systemic Reorganization in Swiss Mice

Environmental Toxicology, EarlyView.
ABSTRACT Microplastic (MP) pollution is widely recognized as an emerging environmental threat. Yet, most studies still rely on controlled experimental conditions that poorly reflect environmental complexity, potentially underestimating risks under realistic scenarios, particularly during short‐term exposures. Here, we tested whether acute oral exposure

The Effect of Pseudo‐Global Warming on the Weather‐Climate System of Africa in a Convection‐Permitting Model

Geophysical Research Letters
The African easterly jet (AEJ) and the West African Monsoon (WAM) can largely modulate high‐impact weather over Africa and the tropical Atlantic. How these features will change with a warming climate is just starting to be addressed due to global climate

Extreme rainfall in southern China in April 2024 and its potential link to weather events across south Asia

Weather, EarlyView.
This study documents the unseasonal and prolonged heavy rain events which occurred in southern China during April 2024. In this series of extreme rainfall events, Guangdong province recorded extreme rainfall exceeding 6‐sigma of climatology, with eleven cities reporting record‐breaking rainfall.

On Tropical Cyclone Fullness

Geophysical Research Letters
A series of recent papers in Geophysical Research Letters and the Journal of Geophysical Research Atmospheres have explored the usefulness of a new “fullness” metric characterizing the ratio of the inner and outer core size of tropical cyclones and ...
