  "term": "Tangent linear model",
  "field": "Meteorology and atmospheric science",
  "definition": "A numerical model that solves the tangent linear equations, representing the linearized dynamics of a full nonlinear atmospheric or oceanic model. This model calculates how small initial perturbations evolve over time. It is a core component of advanced data assimilation schemes and ensemble forecasting techniques.",
