A bomb cyclone is a storm that strengthens so fast that the central atmospheric pressure plunges 0.71 of an inch (24 millibars) or more in 24 hours or less. The central pressure in Tuesday's bomb ...
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.
A bomb cyclone's winds can reach hurricane force - 74 miles (119 km) per hour - and stronger. These storms tend to form during winter and can spawn copious amounts of precipitation.
A powerful extratropical cyclone developed c. November 18, 2024, in the Northeast Pacific and struck the Western United States and Western Canada. [9] [10] The storm underwent bombogenesis, rapidly dropping its central pressure [11] to a record-tying level of 942 millibars (27.8 inHg). [9]
In most regions, if the atmospheric pressure drops at least 24 millibars within 24 hours, it is considered a bomb cyclone. Bomb cyclones can occur when a cold air mass collides with a warm air ...
The bomb cyclone had a minimum central pressure of 942 millibars (27.8 inHg) at its peak, making it the most powerful cyclone recorded in the Northeast Pacific. [2] The system had severe impacts across Western North America, before dissipating on October 26. The storm shattered multiple pressure records across parts of the Pacific Northwest ...
As a major storm moves in to blast the Northeast U.S. with high winds and heavy rain this week, many may be hearing the term "bomb cyclone." You may have heard or read about a bomb cyclone or a ...
The powerful “bomb cyclone” will combine with an atmospheric river to unleash over a month’s worth of rain, hurricane-force wind gusts and feet of mountain snow to parts of the Pacific ...
