The largest typhoon in history slammed into southern Asia in the Philippines today (2013).
-
It's so big.
-
They're calling it a "super typhoon."
-
Hey everyone, Trace here for DNews, answering a long-held question in a lot of people's minds: "What's the difference between a hurricane and a typhoon?"
-
We hear both words a lot.
-
They're both storms that get names.
-
The super typhoon hitting Asia right now (2013) is named Haiyan or Yolanda, by the way.
-
The main difference between a hurricane and a typhoon, believe it or not, is simply where the storm occurs.
-
According to NOAA (National Oceanic and Atmospheric Administration), hurricanes form in the northern Atlantic, north eastern Pacific and South Pacific.
-
Typhoons form in the northwestern Pacific specifically.
-
There are also cyclones, I forgot all about them, which form in the southwest Pacific Ocean and the Indian Ocean.
-
Science likes naming things, and they're very thorough.
-
Basically there are three names for the same big spinning storms.
-
And one cool fact, the word hurricane comes from the name of one of the Mayan gods, Huracan, who helped create the world.
-
No big deal.
-
Other than location, is there anything unique about each type of storm?
-
Not really.
-
All three storms share humble beginnings as tropical storms.
-
Each begin over warm oceans where there are high levels of air moisture and wind.
-
If the right conditions persist, then these spinning storms will grow.
-
And when they reach sustained internal wind speeds of 74 miles [119 kilometers] an hour, they can bring torrential rain, flooding and all the other hallmarks of a big storm like that.
-
The location of the typhoon, cyclone or hurricane determines the direction it spins.
-
Just being a typhoon doesn't mean it will spin in a specific direction.
-
Same with a hurricane, storms can spin either way.
-
All storms forming in the northern hemisphere spin counterclockwise, while those forming in the southern hemisphere spin clockwise, easy-peasy.
-
So what about this super storm thing?
-
We just had one in the U.S. last year (2012) with hurricane Sandy that became superstorm Sandy, and now Asia has a super too.
-
Are those the same thing?
-
Not at all.
-
I spoke with Dennis Feltgen at the National Hurricane Center, and in the U.S. the super storm moniker is completely made up by the media.
-
However, the super typhoon?
-
That's a real science thing.
-
It's a ranking that's done on that side of the world, and it means a sustained surface wind of at least 150 miles [241 kilometers] an hour, high-end is sustaining at 195 [314 kilometers per hour] with gusts up to 235 [378 km/h].
-
Holy crap!
-
In the Atlantic where hurricanes live, they typically appear from June to November, and there are maybe a dozen a year.
-
But the Pacific typhoon, that can happen anywhere from May to December and there may be as many as 30 in a year.
