Mesoscale and microphysical processes leading to extreme hourly rainfall prior to the merger of two mesoscale convective systems in Central China

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Short‐term extreme rainfall can be produced by the variation of low‐level warm moist airflow during mesoscale convective systems (MCSs) approaching another. The cold outflow of the rapidly moving MCS intensifies the warm moist airflow in front, enhancing the convergence and ascending motion in the quasi‐stationary MCS.

A composite‐loss graph neural network for the multivariate post‐processing of ensemble weather forecasts

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The dual graph neural network (dualGNN), trained with a composite loss combining the energy score (ES) and variogram score (VS), consistently outperformed models optimized solely for ES or the continuous ranked probability score in the multivariate setting, as well as empirical copula approaches.

Customization of Limited Area Model for complex orography territories: the WRF and the WRF-Chem UniMe model

Atti della Accademia Perloritana dei Pericolanti. Classe di Scienze Fisiche, Matematiche e Naturali
Since ancient times, knowledge of weather conditions has been essential for human survival and for planning activities. In this context, atmospheric forecast models play a key role in weather studies, contributing significantly to understand and predict short- and long-term weather changes. In the field of atmospheric modelling, weather forecast models

Assessing the role of urban blue space in summer outdoor thermal regulation in northwestern Europe: A hectometric Weather Research and Forecasting modelling on idealized urban landscape

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Using hectometric Weather Research and Forecasting simulations, we examine how urban blue spaces mitigate extreme summer heat in northwestern European cities through neighbourhood‐scale cooling mechanisms. Results show horizontal advection dominates cooling by mixing cooler air from waterbodies with warmer urban air, providing ∼50W·m−2$$ \sim 50\kern0 ...

Performance evaluation of regional weather predictions with the Model for Prediction Across Scales – Atmosphere (MPAS‐A) over the Maritime Continent

Quarterly Journal of the Royal Meteorological Society, EarlyView.
As part of the ongoing efforts to develop next‐generation forecasting systems at the Meteorological Service Singapore, this study presents the setup and evaluation of the SINGV_NG(MPAS) system. Overall, the SINGV_NG(MPAS) system outperforms European Centre for Medium‐Range Weather Forecasts (ECMWF) deterministic forecasts in capturing heavy rainfall ...

Moisture and wind effects of Rossby waves on Western Pacific Intertropical Convergence Zone breakdown events

Quarterly Journal of the Royal Meteorological Society, EarlyView.
(a) Organized convection: clouds are clustered at the southern edge of the domain, aligning with the warmest SST. Northeasterly winds prevail, facilitating convection confinement to the southern part of the domain. (b) ITCZ breakdown: the clouds are spread throughout the domain.

Application of WRF Model for Vehicular Pollution Modelling Using AERMOD

Atmospheric and Climate Sciences, 2015
Vehicular pollution is becoming significant in urban areas because of increasing population. This is at ground level, so it gives high population exposure. In this study, Chembur, which is the most polluted area in Mumbai city due to industrial and vehicular sources, is selected for vehicular pollution modeling using AMS/EPA Regulatory Model ...

Assessing high‐resolution numerical models and bottom‐boundary factors for a Mediterranean heavy precipitation event

Quarterly Journal of the Royal Meteorological Society, EarlyView.
State‐of‐the‐art, convection‐permitting NWP models reproduced the main features of the October 22–23, 2019 heavy precipitation event in Catalonia. However, slight configuration changes yielded varying streamflow responses and statistical performance, highlighting the challenge of simulating these events in Mediterranean medium‐sized basins ...
