  "term": "Confluence",
  "field": "Meteorology and atmospheric science",
  "definitions": [
    "A meteorological pattern where streamlines or isobars converge, indicating a region where air parcels are moving closer together horizontally. This convergence often leads to upward vertical motion in the atmosphere, which can enhance cloud formation and precipitation. It is a key indicator of atmospheric dynamics and weather development.",
    "A pattern of wind flow in which air flows inward toward an axis oriented parallel to the general direction of flow. It is the opposite of difluence. Confluence is not the same as convergence. Winds often accelerate as they enter a confluent zone, resulting in speed divergence which offsets the (apparent) converging effect of the confluent flow."
