1989 M. E. Adams Anat. ‘Bomb’ (M.Sc. thesis, N. Carolina State Univ.) 11 Climatology shows that a high frequency of ‘bombogenesis’ occurs over the ocean.

2019 Palm Beach (Florida) Post (Nexis) 16 Mar. a1 When a storm undergoes bombogenesis it means the counterclockwise spin of the low pressure system is creating a vacuum that drops atmospheric pressure by at least 24 millibars in 24 hours.
