Do the Wettest Days Occur Together? A Global Analysis on Disentangling Precipitation Intensity From Seasonal Timing

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract Current precipitation analysis focuses on extreme events or total amounts but misses a critical question: when does the majority of precipitation occur during the year? We introduce a framework that separates two fundamental aspects of precipitation patterns: how many of the wettest individual days contribute to annual totals versus what is ...

Two Cycles of Devonian–Triassic Extension and Compression in the Altai Accretionary Wedge: Insights From Tsogt Core Complex

Tectonics, Volume 44, Issue 12, December 2025.
Abstract The Altai Accretionary Wedge in the Mongolian Altai records a polyphase geodynamic evolution involving two extensional–compressional tectonic cycles, constrained by petrostructural analysis and zircon, monazite U–Pb, and Ar–Ar geochronology. The studied section includes a southwestern high‐grade and a northeastern low‐grade domain, previously ...

Features of human occupation along the Sosva and Tavda rivers during the Paleolithic Age (Northern Transurals) [PDF]

Вестник археологии, антропологии и этнографии
The Tavda River is formed by the confluence of the Sosva and Lozva rivers, which allows these waterways to be regarded as a single hydrological complex. An initial attempt to occupy the banks of the Tavda River occurred 25–27 thousand years ago.

Spatiotemporal Variations of Terrestrial Water Storage and Driving Factors in the Water Towers of Northwest China Based on GRACE and Multi‐Source Data Sets

Water Resources Research, Volume 61, Issue 10, October 2025.
Abstract Mountains represent important water towers and thus are the primary water suppliers for downstream areas. However, divergent trends in terrestrial water storage (TWS) in water towers and their driving factors have not been clarified. This study investigated water tower units (WTUs) in Northwest China (NWC) and used GRACE/GRACE‐FO and multi ...
