Undular Bore

In meteorology, an undular bore is a wave disturbance in the Earth's atmosphere and can be seen through unique cloud formations. They normally occur within an area of the atmosphere which is stable in the low levels after an outflow boundary or a cold front moves through.

In hydraulics, an undular bore is a (weak) bore with a standing wave pattern at the downstream (subcritical) side.

Famous quotes containing the word bore:

    So we may never
    Again feel fully confident of the stratagem that bore us
    And lived on a certain time after that. And it went away
    Little by little, as most things do. To profit
    By this mainstream is today’s chore and adventure.
    John Ashbery (b. 1927)
