· 预报档案 · 已按第 12 条只取 generated_at 严格早于当日的轮次
Calibre: observed — values come from monitoring stations and satellites, no model forecast. Entries backfilled from the forecast archive are labelled as such and never mixed in.
⚠ Gap notes and source annotations below are currently written in Chinese only — they are shown untranslated rather than omitted, so no information is lost.
Data gaps (stated, not hidden)
· 结束判定 = 首个不达标日。这是我们的判定,不是官方热浪定义 —— 马来西亚气象局(MET Malaysia)对热浪另有标准,本系统未接入其通报。
· 本条门槛:生理线 ≥38°C 且 ≥本地 P90(41.3°C),连续 ≥3 天。
· 本条回填自预报档案(event_history.events),不是实测。已按宪法第 12 条只取 generated_at 严格早于当日的轮次,无 look-ahead。
