Meridional Flow

(Meridional Current)
(north-south air circulation)

Meridional Flow (or Meridional Current) means fluid (e.g., a planet's Atmosphere) circulation between the equator and polls, parallel to longitudes, i.e., north-to-south or south-to-north. This type of circulation causes Temperature extremes. Conversely, east-to-west or west-to-east air flow is termed Zonal Flow.

The terms are also used to describe convection, e.g., in stars or in geologically active planets.
