Dynamics and model representation of two contrasting extreme precipitation events in the Sahel
Quarterly Journal of the Royal Meteorological Society, EarlyView.Hovmöller diagrams of the two investigated extreme precipitation events in Mali are shown for (i) IMERG observations, and ICOsahedral Nonhydrostatic model (ICON) runs with parameterization of explicit convection (ii) enabled and (iii) disabled. This work highlights that the commonly perceived benefit of using explicit convection in a state‐of‐the‐art ...

Windows of opportunity in subseasonal weather regime forecasting: A statistical–dynamical approach
Quarterly Journal of the Royal Meteorological Society, EarlyView.This study explores how the atmospheric state at initialisation creates windows of opportunity for improving week 3 forecasts of weather regime activity. Greenland blocking activity increases following Madden–Julian Oscillation phases 7, 8, and 1 and weak stratospheric polar vortex states, revealing patterns exploitable by statistical models.

A pilot variational coupled reanalysis based on the CESAM climate model
Quarterly Journal of the Royal Meteorological Society, EarlyView.Variational data assimilation of in‐situ and satellite ocean data and reanalysis atmospheric data into an intermediate complexity Earth system model is possible by adjusting the surface fluxes and internal model parameters. This pilot application requires nearly complete information on the atmospheric state for synchronization.

The role of soil moisture in the inland penetration of Indian monsoon low‐pressure systems
Quarterly Journal of the Royal Meteorological Society, EarlyView.We use the Advanced Weather Research and Forecasting model to examine the role of soil moisture in the inland penetration of Indian monsoon low‐pressure systems (LPSs). We find that LPSs penetrate deeply into India despite a dry land surface; however, their inland penetration is adversely affected when there is a reduction in the total surface heat ...

Turbulent snow transport and accumulation: New reduced‐order models and diagnostics
Quarterly Journal of the Royal Meteorological Society, EarlyView.Our new reduced‐order models of snow particle transport provide high‐fidelity calculations of snow accumulation in turbulent flows at significantly reduced computational costs. Additional accumulation diagnostics from the reduced‐order model predict complex patterns of particle concentration in turbulent boundary layers via coherent flow structures in ...

Assessing the impact of model biases on subseasonal forecast skill
Quarterly Journal of the Royal Meteorological Society, EarlyView.Relaxation experiments where the nudging was performed towards bias‐corrected integrations of the same model display significantly improved skill at weeks 3 and 4, particularly in the northern extratropics. This indicates that there is a large potential for improving dynamical subseasonal forecasting skill by improved treatment of model biases.
