  "id": "MLC-T-MET-007442",
  "term": "Multiannual storage",
  "field": "Meteorology and atmospheric science",
  "definition": "The accumulation of water in a reservoir or groundwater system over several consecutive years, designed to buffer against long-term droughts or periods of below-average precipitation. This strategy contrasts with annual storage, which only aims to balance water supply and demand within a single year. Multiannual storage systems are characteristic of arid and semi-arid regions where rainfall variability between years is high.",
