Bombogenesis is a delightfully fun Logos to say , but is substantially less fun to know . This evocative word score a sudden intensification of a storm after a rapid drop in atmospheric pressure , and an all - too - usual phenomena this winter .
The NOAA image is mediocre global wind speed in January and February of this class . White is the historic medium winding - fastness for the past 30 years . Blue is winds quicker than that ( up to 12 nautical mile per hour above average ) , and brown is winds dense ( down to 12 miles per time of day below average ) .
In January and February , we had 20 unique hurricane - force wind events . Of those , 14 spark off a bombogenesis event , dropping at least 24 millibars of press over 24 hours and dramatically intensifying the cyclone .
Compared to the norm , the North Atlantic is having a more severe violent storm time of year than common with high - than - average wind hurrying , disrupt the major merchant vessels corridor . Slower - than - average flatus in the Northeast Pacific have kept storms at true laurel , feeding California ’s drought .
