A new India-Burma Trough Index and its Relationship with Interdecadal Changes of Precipitation over Southern China

Gaoyuan qixiang
The India-Burma Trough （IBT）， a semi-permanent low-pressure system situated on the southern flank of the Qinghai-Xizang （Tibetan） Plateau during the winter half-year， plays a crucial role in modulating winter and spring precipitation patterns across ...

Estimating the geopotential value W0 of the local geoid based on data from local and global normal heights of GPS/leveling points in Vietnam

Geodesy and Cartography, 2013
Currently, the determination of geopotential value W0 of local geoid that best fits local mean sea level at the Zero Tide Gauge Station is getting important in building the National Geoid-Based Vertical System.

Polar‐low track prediction using machine‐learning methods

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Machine‐learning models are developed to produce reliable and efficient forecasts of polar‐low (PL) trajectories 12 hours ahead. A temporal model (RLSTM) benefiting from the rolling‐forecast strategy, improves overall prediction accuracy and is suitable for quick experimentation, while a spatiotemporal model (PL‐UNet), incorporating both historical and

Comparative evaluation of data‐driven weather forecast models performance for medium‐ to extended‐range weather forecasting and tropical cyclone genesis in 2024

Weather, EarlyView.
This study examines the performance of state‐of‐the‐art artificial intelligence (AI) weather forecasting models in 2024. For tropical cyclone genesis forecasts in the western North Pacific, AI models generally perform better than the physics‐based European Centre for Medium‐Range Weather Forecasts (ECMWF) Integrated Forecasting System (IFS ...

Extreme rainfall in Madeira: the June 2023 weather event

Weather, EarlyView.
This study investigates the meteorological conditions behind the extreme precipitation event on 6 June 2023 over Madeira Island, Portugal. The event set a national daily record of 497.5mm and was unusual for occurring in early summer, as most extremes in the region occur in winter.

Application of High‐Order Direct Flux Reconstruction and Stiffness‐Resilient Time Integration to Simulations of Idealized Atmospheric Flows

International Journal for Numerical Methods in Fluids, Volume 98, Issue 4, Page 448-468, April 2026.
The proposed work implements a direct flux reconstruction method for spatial discretization and a stiffness‐resilient exponential time integration method for temporal discretization on the cube‐sphere grid. A space‐time tensor formalism is employed to provide a general representation in any curvilinear coordinate system. This combination enables highly

Hierarchical Testing of a Hybrid Machine Learning‐Physics Global Atmosphere Model

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Machine learning (ML)‐based models have demonstrated high skill and computational efficiency, often outperforming conventional physics‐based models in weather and subseasonal predictions. While prior studies have assessed their fidelity in capturing synoptic‐scale atmospheric dynamics, their performance across timescales and under out‐of ...

Imputing Missing Long‐Term Spatiotemporal Multivariate Atmospheric Data With CNN‐Transformer Machine Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract Continuous physical domains are important for scientific investigations of dynamical processes in the atmosphere. However, missing data—arising from operational constraints and adverse environmental conditions—pose significant challenges to accurate analysis and modeling.

Trends and Circulation Conditions of Precipitation Over the Sudeten Mountains (Central Europe) in the Years 1961–2020

International Journal of Climatology, Volume 46, Issue 4, 30 March 2026.
Significant trends of precipitation totals are visible at seasonal (negative in spring and positive in winter) and monthly level. The deepening rainfall deficit in April in Western Sudetes threatens the stabilisation of forest ecosystems, the preservation of biodiversity and significantly limits water resources for economic use.
