  "field": "Meteorology and atmospheric science",
  "definition": "A numerical integration scheme used in atmospheric models to approximate time derivatives. It calculates the value of a variable at a future time step using values from the current and previous time steps, effectively \"leapfrogging\" over the current state. This method is conditionally stable and requires a small time step to prevent numerical instability.",
