बम चक्रवात, एक भयानक तूफान (A winter hurricane) को दिया गया नाम है, जिसमें तूफान के केंद्र में हवा का दबाव 24 घंटे में कम से कम 24 मिलीबार तक गिर सकता है और यह तेजी से बढ़ता है। बम चक्रवात की वजह से इलाके में भारी बर्फ गिरती है और तेज हवाएं चलती हैं। यह तूफान आमतौर पर सर्दियों के मौसम में आता है। In the 1940s, some meteorologists began informally calling some big coastal storms "bombs."
A bomb cyclone, which occurs through the process known as bombogenesis, is basically a winter hurricane.
bombogenesis occur when a storm's central barometric pressure drops at least 24 millibars in 24 hours. A millibar is a way of measuring pressure. The lower the pressure, the more powerful the storm.
Some storms have intensified as rapidly as 60 millibars in 24 hours. A few bomb cyclones even develop "eyes," similar to the center of a hurricane.
