Subject field(s)
  • Meteorological Forecasting, Data Measurement and Analysis
  • Climatology
DEF

atmospheric analogs: Similar atmospheric states that may have occurred at quite different times, usually in different years but the same season.

CONT

While the presence of a low-level jet is not required for thunderstorms to occur, the downstream convergence associated with the jet core explains the increased potential for nocturnal thunderstorm development. This low-level jetstream has been described as an atmospheric analog to the Gulf Stream current and its diurnal variation is not well understood.
