  "id": "MLC-T-MET-006931",
  "term": "Level of nondivergence",
  "field": "Meteorology and atmospheric science",
  "definition": "An altitude in the troposphere where the horizontal divergence of the wind field is zero. In a typical baroclinic system, there is divergence in the upper troposphere above a region of surface low pressure and convergence in the lower troposphere, with the level of nondivergence separating these two layers. This level is found near the 500-millibar pressure surface, at an approximate altitude of 5.5 kilometers.",
