  "term": "Strain tensor",
  "field": "Meteorology and atmospheric science",
  "definition": "A mathematical object that describes the deformation of a fluid parcel or continuous medium at a given point. In fluid dynamics, it quantifies how the shape and volume of a small element of air change due to the velocity field, including stretching, shearing, and changes in volume. The strain tensor is symmetric and is used in the Navier-Stokes equations to relate the deformation rate to the viscous stresses within the fluid.",
