Using tree rings, climate model output, & non-stationary SPI, we show how climate change is shaping seasonal rainfall. https://iopscience.iop.org/article/10.1088/2515-7620/ade51f #ClimateChange #Hydrology #WaterManagement26 Aug 2025 12:18 +0000at://did:plc:z3tnrmcy34gnyvb3i3d64ucj/app.bsky.feed.post/3lxciqez4622chttps://bsky.app/profile/staggehydro.bsky.social/post/3lhumogvyr22wNew paper - how does moving window length affect the annual minima?
