  "term": "Helmholtz wave",
  "field": "Meteorology and atmospheric science",
  "definition": "A type of atmospheric or oceanic wave that forms at the interface between two fluids with different densities and relative velocities. These waves are a manifestation of Kelvin-Helmholtz instability, occurring when the shear across the interface is sufficiently strong. They are often observed as billow clouds in the atmosphere, indicating strong wind shear.",
