Bombogenesis

With Storm Ashley raging around us, I was interested in an article that told me about bombogenesis. This article spells out the definition. My barometer works in inches, so it would be a fall of 0.71 inHg in 24 hours. I last set the reading marker a few days ago and it has come down 0.6 inHg in that time. Not bombogenesis but quite a fall. Reading the article carefully shows that it depends on latitude. I can see how but not why. We are 54 degrees North and would then need a fall of 22mb. I converted my readings and had a fall of 21mb, but I think that was over 3 days not 24 hours. It's got me paying more attention to the baromter.
