El Niño – it means the child or the Christ Child in Spanish. However, the name is a terrible contradiction. El Niño conjures the image of a beautiful, cherubic baby. It is certainly not that. One climatologist describes this weather phenomenon as, “mudslides in Los Angeles and golfing in Minneapolis. And there can be a lot of chaos in between.”
Well, what is an El Niño? An El Niño is a warming of the Equatorial Pacific waters. Fishermen in South America gave it the name El Niño because the waters would get warm around Christmas time and the fish would disappear. These days, everybody seems to be talking about it. You can’t pick up a paper or turn on the news without seeing a story. In fact, as I was writing this, an old friend at CBS was doing a piece on it for Sunday Morning. Clearly, El Niño is already a headline maker, and it hasn’t yet kicked into full throttle.
NASA climatologist Bill Patzert at the Jet Propulsion Lab in California has likened this one to one of the all-time greatest monsters, “It’s truly the Godzilla El Niño,” Patzert told me. If it is not the most powerful yet, he believes it soon will be based on the satellite images and data he’s analyzing. And, this El Niño may have played a role in the recent deadly tornadoes in the South and the short sleeve and shorts winter weather in the Northeast.
So why so much interest now? In a word: worry. Really intense El Niño events seem to take place about every 15 years give or take: 1982-83, 1997-98, which is the strongest to date. They have profound impacts on the weather, flooding and mudslides in California; wet, turbulent weather in Texas and along the Gulf Coast; and warm conditions in the Northeast. “So all the pieces on the weather board are rearranged and there’s a lot of volatility not just in the U.S. but across the planet,” according to Patzert.
That volatility left 42 people dead and 260 injured in Central Florida in February 1998. Seven tornadoes touched down overnight during the worst outbreak ever in the state.
Is that or something similar going to happen again? No one knows because as Mike Halpert says, “No two El Niño’s are alike.”
Halpert is Deputy Director of NOAA’s Climate Prediction Center. The scientists there measure El Niño’s strength not only by the ocean’s heat but how the atmosphere is reacting to it. Halpert said, “What we think is really more important isn’t what the ocean does, it’s what the atmosphere overlying the ocean does because, that’s what kicks off the rest of the impacts globally.”
So far, Harpert says, this El Niño is weaker in the atmosphere than the two previous big El Niño events. Does that mean the impacts will be less severe? Possibly but, there’s no way to know. Why? Halpert says there just isn’t enough of an El Niño sample size. He added, “We don’t have good data that goes back thousands of years. I mean we haven’t seen that many of these kinds of things.”
Frankly, it really does not matter where this occurrence of El Niño lands in the power rankings. It’s all about when the dust settles, how bad was it? We’ve already seen the first glimpses. And even though the sample size is small, there’s enough historical data, scientists say, to tell us we need to be prepared.
There’s still time to get prepared, but don’t put it off any longer. Start by making sure you have a NOAA weather radio, plus a smartphone app like FLASH Weather Alerts that includes “follow me” technology and text-to-speech alerting. You can select alerts for all the different weather hazards, including flood, freeze, and tornadoes.
If you know your area is prone to flooding or mudslides, remember “Turn Around, Don’t Drown”, and never cross a flooded roadway. Keep sandbags on hand, and make sure you have up-to-date flood insurance. Do you have emergency supplies on hand including bottled water? You need to! Have you taken a recent inventory of everything you own? If not, do it now. If you are in a tornado threat area, consider installing a tornado safe room or shelter, but make sure it is either built using FEMA 320 or the ICC 500 standard.
For the U.S., the big “worry” months have just arrived. “Beginning in January and February”, Patzert told me, “we should see a convoy of storms coming straight out of the Western Pacific slamming into California and Southwest Texas and these storms actually get pumped up as they go over the Northern Gulf of Mexico and some of the worst damage may be in Florida.”
For all the misery El Niño can dish out, there are a couple plusses. Scientists say it won’t end the drought in California but it should make a dent, and a warm winter saves the U.S. billions in heating costs.
The experts believe this El Niño will likely last into the late spring and could linger into early summer. What comes next? Halpert says, “It’s a good bet that when this El Niño ends the next thing we have will be a La Niña.” During a La Niña, the waters in the Pacific cool off, and the weather patterns change. Where El Niño events put a lid on Atlantic Hurricanes, La Niña’s are like muscle milk to Atlantic storms! Hurricane Season could become interesting.
