Gerstner wave

  "id": "MLC-T-MET-005961",
  "term": "Gerstner wave",
  "field": "Meteorology and atmospheric science",
  "definition": "An exact, rotational solution to the Euler equations for a periodic surface gravity wave on an inviscid, incompressible fluid of infinite depth. In this theoretical model, fluid particles move in circular paths, with the radius of the circles decreasing with depth below the surface. The resulting wave profile is a trochoid, which has sharper crests and flatter troughs compared to a sinusoidal wave, making it a more realistic representation of steep water waves.",
