  "id": "MLC-T-MET-006243",
  "term": "High index",
  "field": "Meteorology and atmospheric science",
  "definition": "A state of the atmospheric general circulation characterized by a strong, predominantly zonal (west-to-east) flow in the mid-latitudes. This pattern involves a fast-moving jet stream with minimal meandering, which steers weather systems quickly across the globe. A high-index circulation typically results in more moderate and predictable weather patterns with less pronounced temperature contrasts compared to a low-index state.",
