  "term": "Looping",
  "field": "Meteorology and atmospheric science",
  "definitions": [
    "A type of smoke plume behavior observed from industrial stacks, characterized by large, undulating motions that resemble a series of loops. This occurs under unstable atmospheric conditions, where strong vertical mixing causes the plume to rapidly disperse both horizontally and vertically. Looping plumes can lead to high ground-level concentrations of pollutants close to the source.",
    "A pattern of plume dispersion in an unstable atmosphere, in which the plume undergoes marked vertical oscillations as it is alternately affected by rising convective plumes and the subsiding motions between the plumes."
