美国国家公共电台 NPR Scientists Warn 'Bomb Cyclone' Brings Strong Winds, Cold Temperatures

STEVE INSKEEP, HOST:
The winter storm hitting the East Coast today is part of a pattern of weather over a number of days. It had a prologue 1, and it's going to have an epilogue, too. So let's talk it all through in sequence. What comes before a bomb cyclone 2 - the storm itself - and what comes after for much of the country? NPR's science reporter Rhitu Chatterjee has been tracking the storm. She's in our studios. Good morning.
RHITU CHATTERJEE, BYLINE 3: Good morning, Steve.
INSKEEP: OK, so what was the preliminary to all of this?
CHATTERJEE: So the extremely cold temperatures that much of the U.S., especially eastern part of the country, has been experiencing over the past 10 days was one of the key ingredients for this storm. These cold temperatures were caused by really cold air, what scientists call jet streams, coming down from up north into most of the country. And when that air moved further south and met warm, moist air over the Atlantic, it caused a dramatic drop in air pressure, which is what scientists called a bomb cyclone.
INSKEEP: OK, so this cold air that my mom felt in Indiana, single digits 4, or in upstate New York or here in Washington D.C. where it was in the teens, that is one of the ingredients of this bomb cyclone.
CHATTERJEE: One of the key ingredients, yeah.
INSKEEP: Hits some warmer air coming up from the Caribbean or wherever. And what is a bomb cyclone as opposed to any other storm?
CHATTERJEE: Well, that's just a scientific term that describes this kind of cyclone that's formed by these two masses of warm and cold air. When they collide, it causes a very, very rapid drop in air pressure, and that's what they call bomb or bombogenesis. It's just a fancy term to describe this dramatic drop in air pressure in a very powerful storm that is going to intensify 5 as it moves north on the - along the East Coast.
INSKEEP: What kind of effects could we see?
CHATTERJEE: So as we know, parts of the southern U.S. have already gotten snow - parts of the U.S. that don't usually get snow.
INSKEEP: Sure.
CHATTERJEE: But New England is really the region that's going to be really badly affected 6 because the storm is going to intensify as it goes north. There are going to be very powerful winds, snow, 12 to 18 inches or more. There could be power outages. And people should be thinking about where they could stay warm if they lose power.
INSKEEP: So what's the epilogue, then, to this bomb cyclone?
CHATTERJEE: Well, this storm is going to subside 7 by tomorrow. But what it's going to do is it's going to pull in more of that cold, frigid 8 Arctic air over most of the country. So both on the East Coast, the Northeast and big chunks 9 of the middle of the United States, the Great Lakes region, are going to see very, very frigid temperatures.
INSKEEP: Wait a minute. This super low pressure area, is it kind of like a black hole? It's going to suck air in its direction.
CHATTERJEE: Exactly, exactly.
INSKEEP: And it's going to be Canadian air, really cold air.
CHATTERJEE: Yeah, for many days to come.
INSKEEP: Meaning if I live in the Great Lakes or anywhere else, I'm going to be feeling the effects of this.
CHATTERJEE: Yes. Most of the middle of the country and east of that.
INSKEEP: Hundreds of miles from the coast. So I have to ask, as we do any time there's an extreme weather event like this or something we haven't really heard of, and I think most people hadn't heard of a bomb cyclone before, although I'm sure...
CHATTERJEE: It's pretty common actually.
INSKEEP: ...Meteorologists have. Is climate change any kind of a factor here?
CHATTERJEE: So, you know, scientists have a much better idea of climate change's connection - influence on hurricanes, but with these kinds of winter storms, they really don't know. The models aren't there quite yet, and they don't know whether there is a connection here.
INSKEEP: Well, listen, try to stay warm today, OK?
CHATTERJEE: You too, Steve, thank you.
INSKEEP: That's NPR's Rhitu Chatterjee.
