The East Coast of the United States is witnessing deep freeze as the region is gripped by a massive winter storm. This storm, which is slamming the region with heavy snow has been given the name of 'Bomb Cyclone' by the weather scientists. This bomb cyclone has been predicted to pertain on the region throughout the weekend. The storm, which began in the Gulf of Mexico, has been wreaking havoc along the US Eastern Seaboard. Wind gusts were reported to hit more than 70 miles per hour in places and some areas saw as much as 18 inches of snow. The media reports suggest at least 19 deaths from the huge storm and bone-chilling cold. Schools and government offices have been closed because of the deadly bomb cyclone and thousands of flights have been cancelled. What is a Bomb Cyclone? The real term for the phenomenon used by the meteorologists is Bombogenesis. Bomb cyclone is a shorter way of saying it, which is better for social media. After \u201cbomb cyclone\u201d appeared in a Washington Post story, earlier this week, the weather term became popular, or \u201cblew up,\u201d on social media. It became a top trending topic. According to the National Oceanic and Atmospheric Administration (NOAA), a storm undergoes bombogenesis when its central low pressure drops at least 24 millibars (unit of pressure) in 24 hours.

The 'bomb cyclone' occurs when a low-pressure system\u2019s central pressure falls 24 millibars in 24 hours or less. A low-pressure region is a region where the pressure of the atmosphere at sea level is lower than the surrounding area. When do Bomb Cyclones occur? This can happen when a cold air mass collides with a warm air mass, such as air over warm ocean waters. As of now, many areas in the US have been facing power cuts due to the cyclone. Saturday has been predicted to be the coldest day of the year. The residents of the region have been advised to stay indoors and take proper measures by the state authorities.
