  "term": "Axis of dilatation",
  "field": "Meteorology and atmospheric science",
  "definition": "A line or direction along which a fluid parcel or air mass is undergoing divergence and expansion in its spatial extent. This process often leads to a decrease in velocity or intensity in other directions due to conservation principles. It is a concept used in fluid dynamics to describe deformation.",
