What observations does Barry Zalph have about wind in Louisville?
The Trump administration is backtracking on federal efforts to fight climate change. So city and state governments are stepping in.
We think we are standing what can be the future of energy in Denver.
On the Sunday story, climate solutions on the local level. Listen now on the Up First podcast on the NPR app. You're listening to Shortwave from NPR. Hi, Short Wavers. Emily Kwong here with producer Hannah Chin. Hey, Em. Hey.
What data did Barry gather to investigate wind patterns?
And we have been working on an episode for a listener who has been with us from the very beginning.
I think back to episode one.
This is Barry Zalf. He lives in Louisville, Kentucky.
Though I don't remember what the episode was.
That's because these days, Barry's thoughts are much more consumed by a shift in his daily life. Namely, the wind.
I just have a personal perception that it has gotten considerably windier in Louisville over the 35 years that I've lived here. We're getting lots of wind on dry, clear, or partly cloudy days that we would have never seen before when there wasn't a thunderstorm happening.
Which really bothers Barry because he likes to bike.
What insights does Scott Gunter provide about wind speed trends?
And, well, wind isn't great for bikers.
But to truly figure out whether it was getting windier, Barry did what any good science journalist would do. He went digging for data. And over Zoom, he showed me over 20 years of NOAA data about Louisville's wind patterns.
Share. Can I share a screen?
I love that our listeners make graphs for their questions.
Yeah, it's so good because he wanted to make sure this wasn't a recency bias because Louisville has seen a few windstorms in recent years.
But when I looked at his data across 20 or so years... For every measure, the wind speed is higher for the last 10 years of my data set than for the first five years of my data set.
And that impressed Scott Gunder.
How do atmospheric pressure changes influence wind behavior?
Does Barry want to come back for a graduate degree or something? Like, holy analysis, that is awesome. A few notes maybe, but in general, like, that's really impressive.
So this is Scott Gunter. He's an assistant professor at the University of Louisville with a special focus on extreme weather. And he was excited to see this graph because low-speed winds aren't really something a lot of scientists pay attention to. Researchers like Scott are more worried about severe winds, which the National Weather Service defines as winds above 58 miles per hour. They're the kind of winds that can cause damage. But here's the thing. We all grapple with low-speed winds in our daily lives.
What role does the jet stream play in wind patterns?
To Barry's point, they can be totally disruptive to us as humans, even if they're not turning into high-speed tornado winds or toppling buildings.
Today on the show, we interrogate the wind for Barry. Scott helps us dig more deeply into wind, how severe winds and thunderstorms unfold, and asks the question whether Tornado Alley is shifting as the climate warms. I'm Emily Kwong.
And I'm Hannah Shin. You're listening to Shortwave from NPR.
This week on Sources and Methods, every White House has an official counterterrorism plan, a strategy document, basically. But President Trump's new 2026 plan shifts focus to left-wing extremism. We're unpacking what's in the document and who influenced it this week on Sources and Methods. You can listen on the NPR app or wherever you get your podcasts.
Is Kentucky experiencing a shift in tornado activity?
OK, Scott, so wind is just moving air. How does wind get around and how does it get around so fast?
There's one force in particular that really drives wind, and we call that the pressure gradient force. It's just changes in atmospheric pressure. And we live at the bottom of an atmospheric swimming pool. Just like if you dove underwater in a pool, you can feel that pressure of all that water pushing down on you.
I almost think like we have an ocean above us.
Yes, a thousand percent.
With like currents and pressure gradients.
Yeah, you got it.
What factors contribute to the changing dynamics of Tornado Alley?
And there are areas of high pressure, low pressure that are approaching one another or interacting with one another. If we think about an area of low pressure, that is typically an area of rising air. that rising air causes other air to flow inward toward it.
