Improving heavy precipitation forecasts through phase‐aware nonlinear bias correction of all‐sky infrared radiances using cloud top temperature differences

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study proposes a phase‐aware bias correction framework for all‐sky infrared radiance assimilation. Cloud top temperature differences between observations and model background fields are used to identify cloud‐phase mismatch and cold‐cloud regimes.

Modelling representation errors of atmospheric CO₂ mixing ratios at a regional scale [PDF]

Atmospheric Chemistry and Physics, 2008
Inverse modelling of carbon sources and sinks requires an accurate quality estimate of the modelling framework to obtain a realistic estimate of the inferred fluxes and their uncertainties.

Investigating precipitation growth and decay due to orography using radar rainfall observations in Great Britain

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Precipitation growth and decay due to orography was analyzed using the radar network in Great Britain. Storm direction and speed modulate the intensity of precipitation growth or decay. Windward slopes predominantly exhibit precipitation growth, while leeward areas show precipitation decay.

Measuring Clear‐Air Vertical Motions From Space

AGU Advances
Measuring vertical velocity in the atmosphere has long been a challenge due to its small magnitude. Taking advantage of the modulation of free tropospheric relative humidity by vertical motions, we derive analytical relationships that allow us to ...

Progressive emergence of canopy gravity waves during the afternoon–evening transition

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Large‐eddy simulations are used to investigate the afternoon‐to‐evening transition of turbulence over a forest canopy and its coupling with atmospheric boundary‐layer dynamics. As surface cooling strengthens stability and weakens near‐canopy winds, canopy turbulence transitions progressively to internal gravity waves that dominate the evening flow ...

The Mediterranean Extreme Events Experiment and storm Harry in January 2026

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This article introduces the Mediterranean Extreme Events Experiment (M3E) – a new project consisting of partners from Europe and the United States – whose main objective is to improve the weather forecasting of extreme events in the Mediterranean region via the deployment of drifting buoys with barometers (shown).

Spontaneous zonal symmetry breaking of tropical rain belt

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Precipitable‐water snapshots show how a sea surface temperature (SST)‐forced tropical rain belt can remain zonally elongated or spontaneously reorganize into a localized convective cluster. The simulations identify the SST conditions favoring this zonal convective self‐aggregation and relate the transition to changes in boundary‐layer circulation and ...

Characteristics of quasi‐stationary band‐shaped precipitation systems in Japan between 1989 and 2022

Quarterly Journal of the Royal Meteorological Society, EarlyView.
(a) Annual occurrence frequency of QBPSs (green bars), five‐years moving average (blue line), and regression trend (red line) for 1989–2022. (b) Distribution of the geographical occurrence frequencies of QBPSs with a 5‐km resolution for 1989–2022. Quasi‐stationary band‐shaped precipitation systems (QBPSs) are a major cause of localized heavy rainfall ...

Unusual vertical oscillations of a radiosonde

Weather, EarlyView.
In summer 2023 in southern England, several unusual balloon launches were observed which descended for a few minutes before resuming ascent. This unusual vertical oscillation was repeated several times in a ‘roller‐coaster’‐like pattern. This article discusses the behaviour of the balloons.

Intercomparison of mesoscale meteorological models

, 2004
In the framework of the RAPHAEL EU project, a series of past heavy precipitation events has been simulated with different meteorological models. Rainfall hindcasts and forecasts have been produced by four models in use at various meteorological services or research centres of Italy, Canada, France and Switzerland. The paper is focused on the comparison
