Ageostrophic advection

  "id": "MLC-T-MET-003361",
  "term": "Ageostrophic advection",
  "field": "Meteorology and atmospheric science",
  "definition": "The transport of an atmospheric property, such as temperature or vorticity, by the ageostrophic component of the wind. This process is a key driver of vertical motion in the atmosphere, linking upper-level divergence and convergence patterns to surface pressure changes. Ageostrophic advection is particularly strong in the entrance and exit regions of jet streaks, where it contributes to cyclogenesis.",
