Bombogenesis:
To understand bombogenesis, you need to first remember the basics of high and low pressure. High pressure tends to clear the skies and calm the winds. Low pressure tends to pull in wetter air and gusty winds. Thus, the higher the pressure, the calmer it’ll be, and conversely, the lower the pressure, the stormier it’ll be.
Pressure? Yes, we measure the state of the atmosphere in millibars. “Static” or standard low pressure is about 1013 mb. Low-pressure systems tend to be in the upper 900 mb range.
As a storm forms, we refer to its “genesis” to borrow the biblical term – it is growing. If a storm grows quickly, it’s called rapid intensification. If a storm’s central pressure drops more than 24 mb in 24 hours, that’s bombogenesis. [krem2]
Sounds a bit silly. Noted in this Ryan Hall video.
