  2. Jet stream - Wikipedia

    en.wikipedia.org/wiki/Jet_stream

    The northern polar jet stream is the most important one for aviation and weather forecasting, as it is much stronger and at a much lower altitude than the subtropical jet streams and also covers many countries in the northern hemisphere, [38] while the southern polar jet stream mostly circles Antarctica and sometimes the southern tip of South ...

    en.wikipedia.org/wiki/Atmospheric_circulation

    These ultra-long waves determine the path of the polar jet stream, which travels within the transitional zone between the tropopause and the Ferrel cell. By acting as a heat sink, the polar cell moves the abundant heat from the equator toward the polar regions.

  4. Rossby wave - Wikipedia

    en.wikipedia.org/wiki/Rossby_wave

    Meanders of the Northern Hemisphere's jet stream developing around the northern polar vortex (a, b) and finally detaching a "drop" of cold air (c). Orange: warmer masses of air; pink: jet stream; blue: colder masses of air. Rossby waves, also known as planetary waves, are a type of inertial wave naturally occurring in rotating fluids. [1]

    Antarctic Circumpolar Current (ACC) is an ocean current that flows clockwise (as seen from the South Pole) from west to east around Antarctica. An alternative name for the ACC is the West Wind Drift .
