Increasing urban flash flood risk attributable to both climate and development
Quarterly Journal of the Royal Meteorological Society, EarlyView.A new event impact attribution methodology that combines convection‐permitting climate model data with flood inundation modelling was used for a five‐hour flash‐flooding event in the suburbs of Leeds in 2014. The results show increased urban flood extent due to both climate change (+16%) and increased urbanisation (+29%).

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 ...

Snow Status (dry/wet) by MW radiometry
This product indicates the status of the snow mantle, whether it is wet or dry and, in time series, thawing or freezing, by multi-channel MW observation (middle frequencies).

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 ...

Enhancing severe convection forecasts with microwave radiance assimilation in limited‐area models
Quarterly Journal of the Royal Meteorological Society, EarlyView.Microwave satellite radiances remain largely underexploited in convection‐permitting limited‐area models. We assess the assimilation of humidity‐sensitive radiances from the MHS instrument in the operational ICON‐2I model, improving the precipitation forecast of a severe convective event over the Marche region, Italy, substantially by correcting ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.Overconfident sea ice forecasts pose a challenge in subseasonal prediction. To test a potential way to address this issue and account for sea ice model uncertainty, this article investigates a stochastically perturbed parametrisations (SPP) scheme for sea ice in a prototype CY49R2 configuration of the coupled IFS‐NEMO4‐SI3 system. The results show that

Compaction or removal of wet snow by traffic
, 1971 Observations were made of the free-water content of snow on roads and its behavior under traffic. A Tapley decelerometer was used to measure the skid resistance of the snow-covered roads. It was found that snow having a free- water content of less than 15 percent was compacted by traffic and formed a slippery surface on which a deceleration value of 0 ...
