  "id": "MLC-T-MET-009515",
  "term": "Telegraphic equation",
  "field": "Meteorology and atmospheric science",
  "definition": "A second-order hyperbolic partial differential equation that models both wave propagation and diffusion, combining terms from both the wave equation and the diffusion equation. It describes phenomena where a signal or quantity propagates at a finite speed while also dissipating. In atmospheric science, the equation is applied in advanced models of turbulent transport and radiative transfer, providing a more physically realistic description of particle or energy dispersion than the standard diffusion equation.",
