The characteristics of squall lines in the Southeast Asia region

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Squall lines over the Maritime Continent were analysed using 20 years of IMERG GPM data and classified into four regional clusters. Significant regional differences were found in their size, intensity, lifespan, and propagation. Nighttime squall lines are primarily driven by the convergence of opposing offshore flows and the convergence of monsoonal ...

Towards a Machine Learning Snowfall Retrieval Algorithm for GPM-IMERG

16th International Conference on Meteorology, Climatology and Atmospheric Physics—COMECAP 2023, 2023
Remote sensing of snowfall has been proved to be a great challenge since the start of the satellite era. Several techniques have been applied to satellite data to estimate the fraction of frozen precipitation that reaches the surface. This study aims at investigating the efficacy of machine learning (ML), and especially deep learning (DL), in ...

Performance of the operational ECMWF ensemble in predicting heavy rain associated with the Emilia‐Romagna flood in May 2023

Weather, EarlyView.
A devastating flood occurred in May 2023 in the Emilia‐Romagna region in northern Italy after 2 days with widespread accumulated precipitation exceeding 150mm. The event was associated with a quasi‐stationary upper‐level cutoff cyclone. This study investigates the performance of the operational ECMWF ensemble prediction system in capturing the cutoff ...

Global Diurnal Precipitation Cycle in the AI Model GraphCast and a 5‐km Unified Model: Challenges and Opportunities

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract This study evaluates the ability of the AI weather forecast model GraphCast to reproduce the global diurnal cycle of boreal summer precipitation, comparing it with Integrated Multi‐satellite Retrievals for GPM (IMERG) satellite observations, the ERA5 reanalysis, and an experimental global 5‐km Met Office Unified Model (UM) which is convection ...

IMERGE-FEP: Improving Relative Free Energy Calculation Convergence with Chemical Intermediates

The Journal of Physical Chemistry B
Alchemical free energy calculations are becoming an increasingly prevalent tool in drug discovery efforts. Over the past decade, significant progress has been made in automating various aspects of this technique. However, one aspect hampering wider application is the construction of perturbation networks to connect ligands of interest.

Precipitation‐Buoyancy Relationships in the Life Cycle of Tropical Mesoscale Convective Systems

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract This study aims to establish process‐level benchmarks linking Mesoscale Convective Systems (MCSs) at various stages of their life cycle to their thermodynamic environment. The relationship between MCS precipitation and an empirical buoyancy measure (BL ${\mathrm{B}}_{L}$) is examined using collocated satellite‐observed MCS tracks and ...
