Sudden Stratospheric Warming

A sudden stratospheric warming (SSW) is an event where the polar vortex of westerly winds in the winter hemisphere abruptly (i.e. over the course of a few days) slows down or even reverses direction, accompanied by a rise of stratospheric temperature by several tens of kelvins. This is considered to be the most dramatic meteorological event in the stratosphere.

Famous quotes containing the words sudden and/or warming:

    To feel most beautifully alive means to be reading something beautiful, ready always to apprehend in the flow of language the sudden flash of poetry.
    Gaston Bachelard (1884–1962)

    Under that wide hearth
    a nest of rattlers,
    they’ll knot a hundred together,
    had wintered and were coming awake.
    The warming rock
    flushed them out early.
    Robert Morgan (b. 1944)
