  "term": "Scintillation",
  "field": "Meteorology and atmospheric science",
  "definition": "The rapid, random fluctuations in the intensity, phase, or angle of arrival of electromagnetic radiation as it propagates through a turbulent medium. In the atmosphere, these fluctuations are caused by small-scale variations in the refractive index due to temperature and humidity inhomogeneities. It is responsible for the twinkling of stars and can affect laser communication systems.",
