Bombogenesis in the North Atlantic
According to the NOAA Ocean Prediction Center, there were 20 unique hurricane force wind events between during January and February 2014. Fourteen storms underwent the process called "bombogenesis," whereby a cyclone rapidly intensifies, dropping at least 24 millibars in pressure over 24 hours. The number and intensity of North Atlantic storms is higher than normally observed - and this feature can be seen in wind speed data from the period. In this image, blues indicate areas with wind speeds that are faster than the 30-year historical average (1981-2000). In addition, the high pressure driving the drought conditions over the Western U.S. can also be seen in the lower than average wind speeds (brown colors) in the Northeast Pacific. The North Atlantic is a major shipping corridor, and the models and analysis provided by the Ocean Prediction Center help mariners to navigate these waters more safely.
