Frictional convergence

  "term": "Frictional convergence",
  "field": "Meteorology and atmospheric science",
  "definition": "The horizontal inflow of air at low levels in the atmosphere caused by the reduction of wind speed due to surface friction. As air slows down near the ground, the Coriolis force is less effective, allowing the pressure gradient force to direct air inward toward lower pressure. This process often occurs in low-pressure systems and can lead to upward vertical motion, contributing to cloud formation and precipitation.",
