Weather: 5 things to know about this winter weather system

Global News, Weather UK

A winter weather system has formed over the eastern U.S. and is expected to strike the Midwest with rain and freezing temperatures. The move prompted residents to be on alert for possible flooding and blizzard conditions.

A bomb cyclone is a powerful winter weather system with winds of at least 39 mph, according to the National Weather Service. Meteorologists said they are not sure if the winter storm will bring in a snow storm.

The name was coined by meteorologists, especially on Twitter.

“If you haven’t been to Twitter and you haven’t learned the term ‘bomb cyclone,’ it describes a strong winter storm that is rare in the U.S. and is occurring for the first time ever during November,” meteorologist Ann Robinson said.

Here are five things to know about this hurricane-like winter system.

1. It is not related to Hurricane Barney.

A hurricane was born this week, named Barney. But, after Monday afternoon’s explosion in strength, Hurricane Barney moved out to sea.

2. What exactly causes a bomb cyclone?

The National Weather Service defines a bomb cyclone as an “explosive cyclogenesis, characterized by rapid vertical drop in atmospheric pressure.” That rapid drop can lead to precipitation.

The Weather Channel: An extreme winter weather event “bomb.”

And the Pacific Extreme Events Network uses the term “bomb” to describe the climactic phenomenon. A blast of wintry, Arctic air.

The cold front “bombed” at such a rapid pace that it left behind cold temperatures over half of the United States and ushered in blizzard conditions through the Southeast, the Weather Channel says. A mix of rain and snow developed.

3. Many weather charts have this new snowstorm name.

The NWS kept bomb cyclone track radar maps and other data online so that people could read them.

One headline on a popular weather chart showed the path of the storm over the United States in recent years with the word bomb.

The Weather Channel shows it on its map with a second word bubble over “bullseye.”

4. The most recent winter storm before this one in the U.S. was called Blizzard Jonas.

This was another “bomb” weather event. It hit at the end of January and quickly merged with another system. Snowfall amounts in the mid-Atlantic region and from Boston north to New York City ranged from 12 to 24 inches.

The Weather Channel: Jonas was a total of 3.9 inches of snow at Boston’s Logan International Airport. Some areas received more than 2 feet.

After it happened, President Donald Trump tweeted to congratulate those that had suffered the storm and eventually picked up the “bomb” name.

5. The “bomb” is very fitting as the name was given to this weather system.

“This storm has caught everyone off guard, and we have called it a bomb in the past to show how explosive this storm is. It does absolutely deserve the name, as I have explained on many occasions. This is unique, as the U.S. has not seen this type of event since 1952,” Meteorologist Tom Kines told Science.

Journalists on Twitter are discussing the cold-related winds and friction created as the hurricane and bomb meet.

Weather Channel: hurricane, explosive cyclogenesis.
