What does the word Bombogenesis mean?
: rapid intensification of a storm caused by a sudden and significant drop in atmospheric pressure : the development or intensification of a bomb cyclone A cyclone is a low pressure system and a bombogenesis occurs when a storm intensifies, rapidly losing 24 millibars of pressure in 24 hours.—
What is a Bombogenesis snowstorm?
Bombogenesis occurs when a storm’s central barometric pressure plummets 24 millibars in 24 hours. It’s a sign that the storm is evacuating air, allowing explosive strengthening. Especially in intense winter storms, vivid lightning, booming thunder and heavy snowfall can occur simultaneously.
Who coined bomb cyclone?
The term was coined by famed meteorologists Fred Sanders and John Gyakum in a 1980 paper, and was inspired by the work of the Swedish meteorological pioneer Tor Bergeron.
Is bombogenesis a real word?
Currently, bombogenesis is listed in very few dictionaries, but the more the word is used in news stories and weather forecasts, the faster it will become an official word. Bombogenesis has been used to describe the process of forming such a storm, and as a term for the storm itself.
What happens during a Bombogenesis?
Bombogenesis, a popular term used by meteorologists, occurs when a midlatitude cyclone rapidly intensifies, dropping at least 24 millibars over 24 hours. A millibar measures atmospheric pressure. This can happen when a cold air mass collides with a warm air mass, such as air over warm ocean waters.
What happens during a bomb cyclone?
A bomb cyclone occurs when a mid-latitude cyclone rapidly intensifies, dropping in atmospheric pressure at least 24 millibars (a measure of pressure) over 24 hours. The lower the pressure, the stronger the storm. Winds off the coast of Oregon will gust 70-90 mph — as strong as a Category 1 hurricane.
What is the difference between a nor’easter and a hurricane?
Nor’easters and hurricanes both form over the Atlantic Ocean. Also, nor’easters thrive and pick up strength from cold air in the atmosphere, while hurricanes thrive on warm air. Nor’easters form off the eastern coast of the United States (blue), while hurricanes are most likely to form in the tropics (orange).
Is a Nor Easter a cyclone?
A: A nor’easter is an extratropical cyclone that affects the northeastern United States and extreme eastern Canada. Nor’easters also can cause coastal flooding, coastal erosion and strong winds.
What is the meaning of the word bombogenesis?
Bombogenesis may be one such word. Or “bomb cyclone,” if you prefer. We (and seemingly everyone else who lives in an area prone to snow) are watching this word, and assessing whether it will enjoy sufficient breadth of use and specificity of meaning to warrant defining.
What does it mean to have an explosive cyclogenesis?
Explosive cyclogenesis (also referred to as a weather bomb, meteorological bomb, explosive development, bomb cyclone or bombogenesis) is the rapid deepening of an extratropical cyclonic low-pressure area. The change in pressure needed to classify something as explosive cyclogenesis is latitude dependent.
When does a bombogenesis occur in a cyclone?
Bombogenesis, a popular term used by meteorologists, occurs when a midlatitude cyclone rapidly intensifies, dropping at least 24 millibars over 24 hours. A millibar measures atmospheric pressure. This can happen when a cold air mass collides with a warm air mass, such as air over warm ocean waters.
What happens during bombogenesis on the east coast?
Winds increase dramatically, and precipitation, including snowfall, can become intense. Blizzard conditions can occur, sometimes accompanied by lightning as the system is bombing out. An example of bombogenesis off the East Coast.
