    Warm equatorial air tends to rise, move away from the equator, cool, and descend, producing ground-level prevailing winds. At higher latitudes the jet stream meanders north and south as it circles the globe. These are continuous effects with daily and seasonal modulations. Mixing over the poles is much more restricted, without daily effects most of the time, but a strong seasonal component due to long Arctic and Antarctic days and nights.
