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 poles, parallel to longitudes, i.e., north-to-south or south-to-north. This type of circulation results in locations experiencing extreme temperature changes. 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.
