  "term": "Perturbation technique",
  "field": "Meteorology and atmospheric science",
  "definition": "A mathematical method used to approximate solutions to complex differential equations by considering small deviations from a simpler, known solution. In atmospheric science, it involves linearizing the governing equations around a basic state to analyze the behavior of small disturbances. This technique is widely applied in studying atmospheric waves and instabilities.",
