Interplay Between Deep Convection and Mesoscale Gravity Waves
Abstract Although the association between precipitation and mesoscale gravity waves (MGWs) is well documented, the feedback mechanisms governing their amplification remain difficult to isolate. This study uses convection‐permitting numerical simulations with 1–4 km grid spacing to investigate a complex MGW event that occurred over the south‐central ...

Abstract Accurately simulating multiphase flows at low capillary numbers remains challenging due to spurious currents and interface discretization errors. We present a systematic comparison of four volume‐of‐fluid (VOF) solvers within the OpenFOAM framework for pressure‐driven Poiseuille–Bingham flow over grooved surfaces: interFoam with classical ...

First considerations on the structure and development of the Iberian thermal low-pressure system
During the summer a thermal low-pressure system is locked over the Iberian Peninsula. We present a first analysis of such a system using the potential vorticity approach.

Deep Learning‐Based Dynamic Segmentation of the Left Atrium in 4D Flow MRI
ABSTRACT Purpose To design a deep learning pipeline for automated, time‐resolved segmentation of the left atrium (LA) from 4D flow MRI data. Methods We studied 100 individuals including 65 patients with atrial fibrillation (AF) and 35 healthy subjects (HS) resulting in 2530 4D flow MRI time‐volumes acquired in different centers and scanners.

A Level Set Method on Particle Flow Maps
ABSTRACT Accurate interface tracking is central to numerical simulations involving moving boundaries, including multiphase flows, free‐surface dynamics, phase‐change problems, and other interface‐driven processes in computational mechanics. Although, level set methods provide a flexible implicit representation of evolving interfaces, their grid‐based ...

Abstract Determining the atmospheric abundance and the emission sources of carbonyl sulfide (OCS) plays a crucial role for the sulfur budget in the atmosphere. In addition to its main anthropogenic and biogenic sources, biomass burning is assumed to be an essential, but not well constrained source of OCS.

Coral Reef‐Level Upwelling in an Internal Wave Hotspot Modulated by Mesoscale Dynamics
Abstract Coral reefs in the northern South China Sea experience some of the world’s most energetic internal waves (IWs), yet records of how these dynamics influence reef‐level conditions are rare. Using over 6 years of temperature data from Dongsha Atoll, we show that IWs drive diel temperature fluctuations that reduce subsurface heat exposure and ...

Abstract The interannual variability of the Southern Hemisphere polar vortex plays a key role in ozone depletion and recovery but this variability and its teleconnection patterns are less understood than in the Northern Hemisphere. Using ERA5 reanalysis data from 1980 to 2022 (43 years), we studied the variability of the Southern Hemisphere vortex by ...
