Rapidly deepening extratropical cyclonic low-pressure area
This article is about extratropical cyclones. For tropical cyclones, see Rapid intensification.
The Braer Storm of January 1993 explosively deepened to a record low of 913 mbar (hPa)
Explosive cyclogenesis (also referred to as a weather bomb,[1][2][3]meteorological bomb,[4]explosive development,[1]bomb cyclone,[5][6] or bombogenesis[7][8][9]) is the rapid deepening of an extratropical cyclonic low-pressure area. The change in pressure needed to classify something as explosive cyclogenesis is latitude dependent. For example, at 60° latitude, explosive cyclogenesis occurs if the central pressure decreases by 24 millibars (0.71 inHg) or more in 24 hours.[10][11] This is a predominantly maritime, winter event,[10][12] but also occurs in continental settings.[13][14] This process is the extratropical equivalent of the tropical rapid deepening. Although their cyclogenesis is entirely different from that of tropical cyclones, bomb cyclones can produce winds of 74 to 95 mph (120 to 155 km/h), the same order as the first categories of the Saffir–Simpson scale, and yield heavy precipitation. Even though only a minority of bomb cyclones become this strong, some weaker ones can also cause significant damage.
