BOMB CYCLONE: DEFINITION, REGIONS AND REASONS
The technical term is “bombogenesis,” and it means the central pressure of a storm, a measure of its power,
drops by at least 24 millibars in 24 hours. Bomb
cyclone is a shortened version of it, better for social media,” said U.S.
meteorologist Ryan Maue, who helped popularise polar vortex in 2014.
A storm is considered a “bomb” when the pressure drops rapidly at
least 24 millibars in 24 hours. Millibar is the
unit of atmospheric air pressure. Bomb cyclones put forecasters on high alert,
because they can produce significant harmful impacts. Two famed
meteorologists, Fred Sanders and John Gyakum, gave this pattern its name in a
1980 study.
What is bomb Cyclone?
bomb Cyclone is a large, intense midlatitude storm with low
pressure at its center, weather fronts, and a variety of associated weather,
ranging from blizzards to severe thunderstorms to heavy precipitation. National
Weather Service (NWS) confirmed “bomb cyclone” — characterized by the explosive
power of rapid drops in atmospheric pressure. Bomb cyclones put forecasters on
high alert, because they can produce significant harmful impacts.
In which region does a Bomb Cyclone occur?
New York , boston, Warren, Rhode Island, Florida, eastern North America --
from Georgia to Canada
How is a Bomb Cyclone formed?
There are many reasons
cited for the formation of Bomb Cyclones.The key ingredient of a
weather bomb is the collision of cooler air with much warmer air, and that is
on hand. A cold front from Canada
dropped temperatures to a low of 17° Fahrenheit (-8° Celsius) in New York
City’s Central Park overnight while in the Atlantic Ocean, the water is warmer
than normal. Cape May in New Jersey recorded a water temperature of 46°F, and
in Georges Bank off Massachusetts, the ocean was 44.6°F, according to the
National Data Buoy Center. Not exactly balmy, but enough to provide the grist
for the bombogenesis mill.
The baroclinic instability is another cause of this as It happens
when a midlatitude cyclone rapidly intensifies and drops at least 24 millibars
in 24 hours.
Bomb cyclones are caused when a cold air mass
collides with a warm air mass, such as air over warm ocean waters.
Over the warmer ocean, heat and moisture are
abundant. But as cool continental air moves overhead and creates a large
difference in temperature, the lower atmosphere becomes unstable and buoyant.
Air rises, cools and condenses, forming clouds and precipitation.
