What is a Weather Bomb?

There are some strange weather terms, haboob, derecho, swullocking, the list goes on and on. How about a weather bomb?

A weather bomb, also known as explosive cyclogenesis, 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 mbar (hPa) or more in 24 hours.

Although these storms are totally different from that of tropical cyclones, bombs can produce strong winds and heavy precipitation.
