By measuring these isotope ratios in atmospheric moisture, scientists gain extra information about where water vapour originated and how it moved through the water cycle. The finding suggests isotope data could become a valuable addition to existing weather models.","why":"New research shows isotope measurements can sharpen weather forecasts, an advance with broad practical interest.","tone":"positive","entities":["heavy water","deuterium","weather forecasting","Physics World"],"summarized_at":"2026-09-28T09:02:55.766643Z","meta":{"via":"scan","lang":"en","term":"physics","source":"Physics World","generic":0.07,"published":"Mon, 28 Sep 2026 08:01:44 GMT"},"nw":0.54,"promo":0.02,"kind":"news_event","importance":1.58,"hidden":false,"hide_reason":null,"judged_at":"2026-09-28T09:00:50.384059Z","title_en":"Heavy water isotopes improve weather forecast accuracy","section_name":"Science","category_name":"Physics","timeline":[{"captured_at":"2026-09-28T09:00:50.004948Z","rank":1,"volume":null},{"captured_at":"2026-09-28T10:22:46.969500Z","rank":1,"volume":null}],"posts":[{"platform":"news","url":"https://news.google.com/rss/articles/CBMikAFBVV95cUxOOGo4SDc4OTRKOTc5ZXpySXE5alhzTmI2TThmTVVMcDJwSDNtS2k4Mkk4QjQyUlBOX25PbkdnaEJ1VDVnSDd6SUtVMWlIdnhveHZCelNFNV8xTkZqemQ0WlVDbnpBVW52VUZfcWdQV3VYOGFaVjdpaVNMOEpGSTRPQjUxLWpOamc5UFlWem12Yk0?oc=5","author":"Physics World","title":"Heavy water isotopes make weather predictions more accurate","snippet":null,"posted_at":"2026-09-28T08:01:44Z","likes":null}],"elsewhere":[],"window":"7d"}}
