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). Man hospitalized after being shot in South Los Angeles - CBS Los Angeles. 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). This map features satellite-radar composite imagery, current temperatures, projected storm tracks and wind speeds. Sanders and Gyakum adjusted the ground rules to vary based on latitude. 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?). The term can be traced back to a meteorological research paper published in a 1980 edition of Monthly Weather Review. So, the millibar requirement can change depending on where the storm forms. However, that benchmark is also based on the latitude of the storm. Generally, pressure must drop 24 millibars (a unit of pressure) within 24 hours. Here's what it means: What makes a storm a bomb cyclone?īomb cyclone is a term given to a rapidly strengthening storm that fulfills one important criterion. Dodgers host holiday party for local kids amid Ohtani frenzy. Mega Millions ticket worth nearly 3M sold at Mar Vista gas station. Although winds continue to calm down, there's a chance Santa Ana winds return by the. You also have to be careful when using it to describe a storm system.īut the term "bomb cyclone" does pop up from time to time in weather stories.
