    FWIW: In the '60s when I was a meteorologist for the US Air Force, backing
    referred to the the change of wind direction against the compass and veering
    with the compass, i.e.  wind at 150 deg veered to 180  deg and backed to 120
    degrees.

    | I always thought of it as backing against the clock but maybe the clocks
    as
    | well as the lows run backwards down there.
    | On a related but different notion are the maps and charts of southern hemi
