Statistical Characteristics of Environments of Precipitating Mesoscale Convective Systems During the Pre‐Summer Season Over South China

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Mesoscale convective systems (MCSs) are known to induce heavy rainfall and pose significant weather hazards in tropical and mid‐latitude regions. Understanding the environmental conditions of MCSs is essential for improving model simulations and operational precipitation forecasts.

Exploring the Influence of Equatorial Waves on a Record‐Breaking Extreme Precipitation Event in Central Sahel: Insights From Convection Permitting Simulations

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The floods of 01 September 2009 in Ouagadougou, Burkina Faso, were among the most severe in the Central Sahel's history, highlighting the region's persistent flood risk. This extreme precipitation event (EPE) was influenced by various atmospheric drivers, including Convectively Coupled Equatorial Waves (CCEWs).

Low Abundances of Ultramafic Components in the Chang'e‐6 Landing Site Basalt and Ejecta Material

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The South Pole‐Aitken (SPA) Basin, the Moon's largest impact structure, holds key insights into lunar evolution, prompting the Chang'e‐6 mission to return first samples for ground‐truth verification. Analysis of over 6,000 grains from the Chang'e‐6 soil returned from the SPA Basin reveals a composition dominated by clinopyroxene (26.5–32.9 vol.

Earlier Flash Drought Onset Driven by Spring Vegetation Greening and Warming

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The onset timing of the flash drought season (TO) critically determines whether these rapid‐intensifying events coincide with sensitive stages of vegetation growth, as droughts occurring early in the growing season can severely undermine ecosystem productivity. However, how TO has evolved under climate change remains unclear.
