Grill That Bird

The hosts ask whether heat lightning is actually a thing.

“Everybody wins.” (06:16)

Questions

Is "heat lightning" a real thing? (00:32)

Our guess
It's just regular lightning, perhaps cloud-to-cloud lightning with no thunder or storm directly overhead.
Reveal the answer
The answer
No. "Heat lightning" is ordinary lightning from a distant thunderstorm that is too far away for the thunder to be heard, and cloud-to-cloud lightning is common.

[00:00] I guess it's time for the under Googles.
[00:02] Oh, we doing under Googles?
[00:11] That was the play of Super Excited.
[00:13] You told us we had to, sir.
[00:16] You said we signed up for it.
[00:21] In the end, it's going to be better and more true
[00:23] than Google can give you.
[00:25] I'm really happy that Niko's here
[00:27] because I don't feel like Harper and I are
[00:29] smart enough to solve this one on our own.
[00:32] This is something that came up over the summer.
[00:36] I'm looking out at the sky and I see a lightning.
[00:39] And I said, that's heat lightning.
[00:42] And my friend said, that's not a thing.
[00:46] There's no such thing as heat lightning.
[00:48] There's just lightning.
[00:51] And I, in my entire life, had thought
[00:53] that heat lightning was a thing.
[00:55] It's summer.
[00:55] It's super hot.
[00:57] There's some way that lightning is created differently
[01:01] than regular lightning.
[01:03] It happens when it's super hot and humid.
[01:05] There's no rain connected to it.
[01:08] There's no thunder connected to it.
[01:09] There's just lightning.
[01:11] And I had heard heat lightning the phrase my entire life.
[01:15] And I want to know if heat lightning is a thing
[01:17] or I've just been lied to my entire life.
[01:22] I say it's a thing.
[01:25] Well, I say it's both a thing and not a thing, right?
[01:28] It's I tend to agree that lightning is lightning.
[01:31] You just walked in the middle of lightning.
[01:33] Lightning is lightning.
[01:34] Like, I don't have a different formation process.
[01:36] It has to do with the movement of electrons
[01:38] from due to static electricity, presumably, right?
[01:41] OK.
[01:42] And so regardless of what the underlying creation
[01:45] of that static is, static electricity,
[01:50] and differential between positive and negative, high and low,
[01:55] it's still lightning.
[01:57] But it is colloquially the thing.
[02:02] It's called heat lightning if there's not a storm cloud.
[02:05] Yeah, but so what I've, at least what I've seen, right?
[02:10] I first witnessed it in Wyoming.
[02:13] And then down in Louisiana, we actually
[02:18] grounded Blackhawks because of heat lightning,
[02:21] is what the flight line told me.
[02:23] But it was basically lightning that's
[02:25] just shooting in the sky, right?
[02:27] It's not hitting the ground, which is, at least to me,
[02:30] the differentiation, right?
[02:32] Where there's no connection to the Earth, right?
[02:35] Potentially, sure.
[02:36] Where it's just shooting across from cloud to cloud.
[02:39] Where most thunderstorms, you have direct connection
[02:43] with the ground.
[02:44] At least that's what I see down in Houston, right?
[02:49] But the underlying causes are still the same.
[02:51] It's still static electricity, high concentration
[02:56] of positive, high concentration, and negative.
[02:58] I guess it's the cause of that static electricity,
[03:01] is what I guess would be.
[03:03] Is it more likely due to the heat
[03:09] that it's in those atmospheres, right?
[03:11] Versus, I don't know, that's just.
[03:16] Right, is the heat lightning the misnomer, right?
[03:19] Or does lightning just, is the actual heat create lightning?
[03:25] Can I have lightning when it's cold, without rain?
[03:32] I have thunderstorms.
[03:34] No, right, without thunderstorms.
[03:36] Like, there's no rain, no thunder.
[03:38] Do I see lightning when it's cold?
[03:40] I don't.
[03:40] So is the flow of lightening?
[03:43] You have lightning, you have thunder.
[03:45] It's certainly less likely, right?
[03:46] Because the cone of friction of friction
[03:51] is going to be lower in the general atmosphere
[03:54] when the temperature is colder, because there's
[03:56] less kinetic energy generally, right?
[03:58] OK.
[03:59] Is that a thing?
[04:02] It seems like a thing.
[04:07] I wish we had a visual microphone.
[04:09] Because work was golden.
[04:14] My confusion is that my understanding
[04:16] of lightning and thunderstorms had
[04:17] to do with the friction between, basically,
[04:20] clouds rubbing together.
[04:22] I feel like that's the misunderstanding, right?
[04:24] Like, are those cumulus?
[04:29] They're just clouds rubbing up against each other.
[04:31] Are they nimbus?
[04:33] Cumulonimbus out of the thunderstorm clouds.
[04:35] OK, cumulonimbus.
[04:37] I think.
[04:38] But aren't those two separate ones?
[04:40] So those two rubbing together causes the friction?
[04:43] So it's when the nimbus comes and messes with the cumulus.
[04:46] Yeah, you've got to cook that dirt.
[04:48] They create the.
[04:50] Cook that bird.
[04:50] Cook that bird.
[04:51] Grill that bird.
[04:52] Grill that bird.
[04:53] Grill that bird.
[04:53] With some lightning.
[04:56] OK, Google, is heat lightning a real thing?
[05:03] Completely false.
[05:04] And heat lightning does not actually exist.
[05:06] The flashes of light you are seeing are indeed lightning.
[05:10] But the lightning from a distant thunderstorm far enough away
[05:13] where the sound of thunder doesn't travel all the way
[05:15] to where you're observing it from.
[05:16] What?
[05:20] This is weather.com.
[05:21] This is AccuWeather.
[05:23] AccuWeather.
[05:26] So why is tail?
[05:27] Also known as silent lightning, summer lightning, or dry
[05:30] lightning is a misnomer.
[05:35] It is clouds from distant thunderstorms
[05:38] that do not appear to have accompanying sounds of thunder.
[05:43] Wow.
[05:46] Cloud to cloud and intra-cloud.
[05:49] Yeah, intra-cloud.
[05:50] Lightning charges may occur between areas of cloud
[05:53] without contacting the ground.
[05:54] When it occurs between two separate clouds,
[05:56] it is known as inter-cloud lightning.
[05:59] And when it occurs between areas of differing electric potential
[06:02] within a single cloud is known as intra-cloud lightning.
[06:05] Inter-cloud lightning is the most frequently occurring type.
[06:08] So I guess that's what I thought the heat lightning was.
[06:12] I didn't think it was like some light bouncing off the horizon
[06:16] or something.
[06:17] Right.
[06:20] So I'll go with Nico's answer and my answer and your answer
[06:24] and say, well, right.
[06:25] Everybody wins.
[06:27] Yeah, fuck the name.
[06:28] We don't need Google.
[06:30] We had this.
[06:32] There's also anvil crawler lightning,
[06:34] sometimes called spider lightning.
[06:36] Ooh.
[06:38] It's created when landers propagate
[06:39] through horizontally extended charge regions
[06:41] and mature thunderstorms, usually the stratiform regions
[06:45] of mesoscale convective systems.
[06:48] I mean, as you do.
[06:49] I mean, we all learned that in grade school, right?
[06:51] Right.
[06:52] Yeah.
[06:53] I don't know what you just said.
[06:59] Coalson tuned me out at horizontally extensive,
[07:02] for sure.
[07:03] Wait, that's when I get excited.
[07:06] I thought it was propagating.
[07:08] That's what I tuned in.
[07:13] Ball lightning.
[07:14] Oh, maybe an atmospheric electrical phenomenon.
[07:16] There may be ball lightning.
[07:18] Coalson, I know what you're, I know your favorite.
[07:21] Yeah, I know what kind of lightning you are.
[07:24] Am I right, right?
[07:25] Sympathetic lightning is the tendency
[07:28] of lightning to be loosely coordinated
[07:30] across long distances.
[07:31] Discharges can appear in clusters
[07:34] when viewed from space.
[07:36] But it is sympathetic.
[07:38] That's my spiritual bar crawl in a nutshell.
[07:44] And you're gonna be loosely coordinated
[07:46] across long distances.
[07:47] That's right.
[07:49] You're here.
[07:50] All right, thanks for listening, everybody.
[07:52] Go Blazers!
[07:56] We can't close with Go Blazers.
[07:58] Go Pacers!
[08:00] Go Blazers!
[08:01] Damn it.
[08:02] He can probably do this all night.
[08:04] I can.
[08:07] Go Blazers!
[08:11] All right, I'll take it this one time.
[08:14] All right.
[08:16] Buy you sympathetic lightning.
[08:20] That's why you're letting me get away with this.
[08:24] Because I'm leaving my discharge all over the country.
[08:31] Barely not from what we heard.
[08:33] I'm so glad I didn't stop recording.
[08:38] You have to grill first to do that.
[08:42] Oh, dear.
[08:43] I'll see if I can get the grill out.
