Zonal Flow

Zonal flow is a meteorological term meaning that the general flow pattern is west to east, or east to west, along the Earth's latitude lines (as opposed to meridional flow). Extratropical cyclones in this environment tend to be weaker, moving faster and producing relatively little impact on local weather.

Famous quotes containing the word flow:

    Along the iron veins that traverse the frame of our country, beat and flow the fiery pulses of its exertion, hotter and faster every hour. All vitality is concentrated through those throbbing arteries into the central cities; the country is passed over like a green sea by narrow bridges, and we are thrown back in continually closer crowds on the city gates.
    John Ruskin (1819–1900)
