bomb


Show Summary Details

Quick Reference

An extratropical cyclone that deepens extremely rapidly, with the central pressure dropping by an average of at least 1 hPa per hour for 24 hours. Bombs occur where there is an upper-level trough and great temperature contrast between a pool of warm oceanic water and its surroundings. Such conditions often exist in the west-central North Atlantic and on the eastern seaboard of Australia, where they are also known as east coast cyclones or east coast lows. Bombs obtain much of their energy from the release of latent heat and thus bear some similarity to tropical cyclones.
