Evaluation and Future Changes of Mesoscale Convective Systems Over the Conterminous United States in High‐Resolution Global and Regional Simulations

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Mesoscale convective systems (MCSs) play a central role in producing extreme precipitation over the conterminous United States (CONUS), yet their simulation and future evolution remain elusive. Here we present a comprehensive, observation‐constrained evaluation of MCSs during 2001–2020 using multisource satellite and in situ observations, ERA5

Sensitivity of East Asian Meso‐β‐Scale Convective Systems Identification to Microphysical Processes in a Convection‐Permitting Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract Mesoscale convective systems (MCSs) are key contributors to heavy rainfall in the East Asian summer monsoon, yet their statistics and internal structure remain difficult to simulate, even in convection‐permitting models (CPMs). This study evaluates the performance of the newly developed Unified Forecast System Double‐Moment microphysics scheme

Advancing Toward Gray Zone: Evaluation of Tropical Cyclones in Key Basins With the 12.5 km High Resolution CAS FGOALS‐f3 Model

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract State‐of‐the‐art climate models are approaching gray‐zone resolutions that can improve the representation of tropical cyclones (TCs), but the extent of these gains remains uncertain. This study evaluates the effect of spatial resolution, particularly near the gray‐zone, using three resolution configurations of the Chinese Academy of Sciences ...

When Ground Truth Has a Footprint: Rethinking Satellite Rainfall Validation

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Accurate evaluation of satellite precipitation products has long depended on comparisons with rain gauge observations, which are often treated as ground truth. Yet this practice overlooks a basic mismatch of scale: gauges measure rainfall at a point, whereas satellite products estimate area‐averaged precipitation. In a recent study, Li et al. (

Spatial downscaling analysis of GPM IMERG precipitation dataset based on multiscale geographically weighted regression model: a case study of the Inner Mongolia Reach of the Yellow River basin

Frontiers in Environmental Science
The Inner Mongolia Reach of the Yellow River Basin is characterized by a relative scarcity of meteorological stations. While satellite precipitation products can complement observations from meteorological stations, their limited spatial resolution ...
