To calculate the pressure drop needed for a bomb cyclone, you take the sine of the latitude where the low pressure is located and divide it by the sine of 60 degrees (and you thought you would never use trigonometry). Since you read down this far, I feel obligated to give you the actual equation - and if you love it, perhaps you should consider pursuing a career in meteorology! They added the term "bomb" because of the explosive power that these storms derive from rapid pressure drops (though Gyakum reportedly doesn't use that word anymore because of its reference to weaponry). Sanders and Gyakum adjusted the ground rules to vary based on latitude. See where rain, snow and ice are affecting the region and plan ahead. Its authors, MIT meteorologists Fred Sanders and John Gyakum, built upon work by Swedish meteorology researcher Tor Bergeron, who had initially defined "rapidly deepening" storms as those that met the 24 millibars-in-24 hours criterion.īut Bergeron was way up in Scandinavia, where storms strengthen much quicker because of the latitude (remember the Coriolis effect?).
