  "term": "Fourier transform",
  "field": "Meteorology and atmospheric science",
  "definition": "A mathematical operation that converts a function of time or space into a function of frequency, revealing the underlying frequencies present in the original signal. It provides a spectrum of frequencies and their corresponding amplitudes. In atmospheric science, it is used to analyze wave structures, turbulence, and periodicities in meteorological time series or spatial fields.",
