Multiscale numerical sensitivity simulations of a mesoscale gravity‐wave event

Quarterly Journal of the Royal Meteorological Society, EarlyView.
High‐resolution WRF simulations of the February 14–15, 1992 STORM‐FEST event show that mesoscale gravity‐wave genesis occurs via geostrophic adjustment within an upper‐level unbalanced jet, while wave ducting governs maintenance. High‐resolution (1 km), improved physical parameterization, and targeted sensitivity simulations demonstrate that upstream ...

Impact of fragmented urbanization on observed precipitation

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study investigates the impact of fragmented urban landscapes on downwind precipitation by applying an innovative observation‐centered approach to an extensive rain gauge network in Belgium. The approach classifies the observations based on the upwind urban land cover fraction, and compares precipitation indices between rural‐ and urban‐labeled ...

A mathematical-physical formulation of a mesoscale limited area model in meteorology

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali
In this paper we give a detailed mathematical-physical derivation of a limited area meteorological model, used in several applications, describing the motions and the behaviour of the atmosphere, in the troposphere layer, at mesoscale range, modeled as a

Recent progress in atmospheric modeling over the Andes – part I: review of atmospheric processes

Frontiers in Earth Science
The Andes is the longest mountain range in the world, stretching from tropical South America to austral Patagonia (12°N-55°S). Along with the climate differences associated with latitude, the Andean region also features contrasting slopes and elevations,

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 ...

Structural changes in the interannual variability of extreme autumn precipitation in eastern Spain and the weakening of synoptic forcing

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Total autumn precipitation in eastern Spain remains stable between 1950 and 2024, masking a substantial internal redistribution between ordinary and extreme rainfall. While torrential precipitation (Rp95) increases and ordinary precipitation (Ro) decreases, the extreme contribution index (Cext) shows a significant positive trend and a structural shift ...

Moist orographic gravity wave drag parameterization reduces the bias of summer rainfall over the Tibetan Plateau

npj Climate and Atmospheric Science
Summer precipitation over the Tibetan Plateau (TP) significantly affects the regional and global climate. In this paper, the orographic gravity wave drag (OGWD) parameterization is revised by incorporating the moisture effect of saturated air into the ...

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.

Mesoscale Verification Using Meteorological Composites

Monthly Weather Review, 2004
Abstract Mesoscale models are often used to explicitly predict discrete, highly structured phenomena. Information regarding the ability of the model to predict events as coherent entities is thus a useful statement of performance. Observational constraints are a significant problem, though, as the shape, size, and intensity of any given event are often

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.
