Space Hangovers
After Hurricane Ida, the hosts ask why hurricanes are named alphabetically and how barometric pressure relates to storms.
“Space hangovers are worse.” (16:28)
Questions
Why do we name hurricanes alphabetically, and when did that start? (00:31)
Our guess
Late 1950s-early 1960s, with alphabetical female names, with male names added later.
Late 1950s-early 1960s, with alphabetical female names, with male names added later.
Reveal the answer
The answer
In the early 1950s the National Hurricane Center used the phonetic alphabet (Able, Baker, Charlie), switched to alphabetical female names in 1953, and added male names in 1978-79. A storm is named once its winds reach 39 mph.

Why does a drop in barometric pressure signal a hurricane? (04:24)
Our guess
A hurricane is a massive low-pressure system that sucks in warm air.
A hurricane is a massive low-pressure system that sucks in warm air.
Reveal the answer
The answer
The eye of a hurricane is extremely low pressure, because warm air rises there, creating a cyclone. The lowest recorded pressure was Typhoon Tip at 870 millibars in 1979.

[00:00] So, you know, just say something clever, and then I'm ready to go. [00:04] Oh, maybe something funny. [00:05] That's right. [00:06] That's right. [00:07] Good to go. [00:09] So, Jason, do you have an under Google Bowl this week? [00:13] Oh, we do an under Google Bowls. [00:26] That was the play of it. [00:28] Super excited. [00:29] You told us we had to, sir. [00:31] You said we signed up for it. [00:34] In the end, it's going to be better and more true than Google can give you. [00:40] Jill asked me today, why do we name hurricanes in alphabetical order? [00:47] When did that start? [00:50] And rotating gender names as well, right? [00:54] Yeah, we do that now. [00:58] That's fairly new. [01:00] Interestingly, it used to be in Cyrillic, but then during the Cold War. [01:06] That joke won't make sense because these are going to be put together so far away. [01:10] Dammit. [01:12] Maybe I'll line them up next to each other for effect. [01:16] So, okay. [01:21] This is doable, right? [01:23] So, when were we starting to get pretty good at predicting weather? [01:28] Good question. [01:33] Are we good at predicting weather? [01:36] So, here's what I learned today. [01:38] This will come out at a different time, but I'm going to put out my thoughts and prayers for Louisiana right now, [01:45] going through a horrific hurricane in Ida. [01:48] And I was watching a bunch of stuff about it, and that's probably why you brought this up as well. [01:51] Your wife probably was watching as well. [01:54] And they were talking about how they can predict hurricanes based on the drop in barometric pressure. [02:00] So, I don't know what that means, but apparently somebody does. [02:04] So, once we start recording barometric pressure, maybe we can start predicting hurricanes. [02:12] So, I mean, the key ingredient to weather prediction is probably radar, no? [02:18] Okay, sure. [02:20] That certainly helps the game. [02:22] Sure, and so what is that? [02:23] For sure. [02:24] That's World War II. [02:25] Okay, so 1940, something. [02:28] So, my assumption would be that the, yeah, the field of meteorology probably had like some exponential growth periods during the 50s and 60s. [02:40] Right. [02:41] So, because they're just using your radar for, you know, submarine battles, and then they're like, hey, I could also use this to look for tornadoes. [02:52] I mean, I imagine the military probably also used it to monitor the weather. [02:57] Like, I don't know if they did or not. [02:59] Pre-satellite. [03:00] Yeah, but I feel like weren't there a bunch of stories in World War II where we were constantly getting surprised by the weather and it screwed up a battle? [03:08] Probably, yeah. [03:09] Whether prediction and whether observation are two very different efforts. [03:13] Yeah. [03:17] I don't know what barometric pressure is, do you? [03:20] I mean, I have a vague idea. [03:22] So, I just want to let you know that I looked at, so this is all I know. [03:26] And I need you guys to, because you guys are smarter than I am. [03:28] But I looked it up. [03:29] I did Google something because they said it's, this hurricane is 938 MBs. [03:37] And I went, I don't know. [03:38] Miller bars. [03:39] Which, here's what I learned. [03:43] A thousand millibars equals one pascal. [03:48] Don't know what any of that means. [03:51] Thank you, Google. [03:54] That's why I'm asking my two smart friends. [03:57] Oh, I also learned that a thousand, it's right around a thousand is the atmospheric pressure at sea level. [04:11] Yeah, yeah, yeah. [04:12] So, one bar is pressure at sea level. [04:17] Yeah, that's basically. [04:18] I think that's what it's defined as. [04:19] Yeah, that's standard. [04:20] Which is also one pascal. [04:23] Or something. [04:24] I don't know. [04:25] Yeah. [04:26] Or the other way around. [04:27] Maybe it's the other way around. [04:28] I don't know why they name them different things. [04:30] Probably pascal was the dude who figured out that, you know, air has mass. [04:35] Right? [04:36] Well, so this is what, so, so if I like, if I'm sinking in the water, right? [04:43] The pressure builds on me the deeper I go down, right? [04:46] Because of the molecules of the heaviness of the water, right? [04:49] Am I, am I being over simplistic here? [04:53] No, that's fine. [04:54] I mean, I mean, yeah, that's right. [04:56] I mean, so pressure, pressure is amount of weight per units area. [05:01] Okay. [05:02] Basically, right? [05:03] So the further you go down, there's no, there's more weight on top of your head, [05:07] right? [05:08] Because there's more water on top of it, right? [05:09] And gravity is pulling it down and your surface area hasn't increased at all. [05:13] So. [05:14] But the surface area of the ocean has or the lake or the whatever. [05:18] No, no, no, no. [05:19] Well, right. [05:20] Above that is above your head. [05:21] Right. [05:22] And so that's how pressure increases in that way. [05:24] Okay. [05:25] Now I understand if I put something in, um, like if I'm blowing up a bicycle [05:31] tire, right? [05:32] I'm adding air to it. [05:33] I'm creating air pressure because I'm, I'm adding air inside a closed [05:38] space. [05:39] Right. [05:40] Right. [05:41] So if I'm in a hurricane, why is it good to have less pressure? [05:50] This is my question. [05:51] Why, why, why do I know that a hurricane is coming? [05:53] Because there's good if you're inside a hurricane. [05:55] Did you just have a visual of Coalson? [05:57] Like hanging onto a tree? [05:58] Like I've lashed myself to a tree so I can make it through. [06:01] Yeah. [06:02] Um, yeah. [06:03] So why would less pressure in the atmosphere be good for a hurricane? [06:09] So basically all major weather events, like a thunderstorm, for instance, [06:15] added super oversimplified, I'm sure. [06:19] But basically that's a warm front and a cold front collide. [06:21] Okay. [06:22] Right. [06:23] Warm front, high pressure, cold front, low pressure. [06:26] Heat equals pressure. [06:28] Cold equals lower pressure. [06:30] Got it. [06:31] Got it. [06:32] So a hurricane is just like a massive, massive, um, low, it's low [06:42] pressure, right? [06:43] Well, no. [06:44] So no, I think, I think what you're getting me to, and I'm, I'm [06:47] going with you because they want to go over warm waters to get [06:50] stronger. [06:51] So I'm wondering if they suck out the pressure from the [06:57] surrounding areas towards the storm, which is why a dropping in [07:02] barometric pressure would be a warning that the hurricane is [07:04] coming. [07:05] Now I'm just spit balling. [07:07] Well, so the warm water creates evaporation. [07:12] Okay. [07:13] Right. [07:14] Which is energy. [07:15] Right. [07:16] Okay. [07:17] Right. [07:18] And so also more potential for rainfall creates a larger [07:20] system. [07:21] Um, but I don't, yeah, I don't know how that directly relates [07:31] to higher, low pressure per se, because I'm not very good at [07:34] meteorology. [07:35] What? [07:36] I thought you were our, uh, the undebeatables meteorologist. [07:41] I mean, it's on your resume. [07:47] Yeah. [07:48] It's the only thing that didn't make sense in your, uh, [07:52] eloquent explanation Coalson was that the hurricane would be [07:58] sucking in things from elsewhere. [08:00] And that would cause low pressure because my understanding [08:05] of the way that air moves and water moves, water vapor moves [08:09] is from high pressure to low pressure. [08:11] That's correct. [08:12] Right. [08:13] And so, yeah, so then I don't know what that, how that helps [08:19] us, but that is a general rule. [08:22] Okay. [08:23] That's good to know. [08:24] Because I clearly have high pressure to low pressure. [08:26] No idea what's going on here. [08:27] So that's, uh, I probably should talk less. [08:29] So the, um, what we're saying is that water evaporates and air [08:33] moves based from high pressure to low pressure. [08:35] That's what you're saying. [08:37] Those are, those are both things that happen. [08:39] Okay. [08:40] All right. [08:45] So in short, I mean, the larger the deviation of a large, I [08:52] mean, one would think, right, the larger the deviation in [08:55] pressure up or down would probably be bad. [08:59] Right. [09:00] Okay. [09:01] Sure. [09:02] Sure. [09:03] If there's this dramatic change in pressure things, that's bad. [09:05] Sudden. [09:06] Yeah. [09:07] Sudden changes in atmospheric. [09:08] Anythings tend not to be, tend not to be. [09:12] Right. [09:13] Well, so this, um, I got us totally sidetracked because the [09:16] original question was when did we start naming hurricanes? [09:19] And I think, um, this, this conversation has helped me. [09:23] I agree with you. [09:24] I think it's in the, uh, I'm going to go with late fifties, [09:29] early sixties. [09:30] Um, and I think we, um, Nowadays, nowadays you, um, uh, we've [09:38] gone through the whole alphabet and like had to start over and [09:41] stuff or go into like Cyrillic, I think. [09:45] Um, but it used to be, you know, you only had about 10 or, you know, [09:50] 20 hurricanes a season. [09:53] Um, I think we've successfully crushed that record over and [09:56] over and over again in the last few years. [09:58] So my guess would be much, much earlier. [10:02] Um, but what they were naming would be the ones that made [10:05] landfall. [10:06] Right. [10:07] I mean, I feel like even the stuff that was hitting the coast [10:11] of Texas and destroying stuff in the 1800s, I feel like those [10:14] had names, but I could be wrong. [10:18] And part of the reason for the proliferation of the sheer [10:21] number of them is just, you know, now we can name all of [10:24] them, whether they make landfall somewhere or not. [10:27] Right. [10:28] Even if there's like a slight, if they're just a tropical [10:30] storm. [10:31] Yeah. [10:32] Yeah. [10:33] Yeah. [10:34] And then we have to skip that letter to go to the next thing. [10:36] Right. [10:37] Yeah. [10:38] Yeah. [10:39] It's a little waste. [10:40] Exactly. [10:41] Why do we even name in tropical storms? [10:44] So, um, so you're thinking we named hurricanes back in the [10:48] 1800s or like, like post post after they destroyed [10:51] something. [10:52] We're like, because here's why I disagree with that. [10:55] Why wouldn't they all be like, that was a, that was hurricane [10:59] asshole, you know, or that was hurricane the worst thing ever. [11:03] You know, we didn't give it cute names. [11:05] They would have been real upset. [11:07] Right. [11:08] But people weren't so crashed back then. [11:10] They all thought they were Shakespeare back then. [11:12] It's probably probably the 1900. [11:14] I mean, it's probably something that you get with. [11:17] Uh, I mean, it, it has to be of like popular press. [11:22] I guess. [11:23] Right. [11:24] A hundred percent. [11:25] Like you need widespread media for it to make any sense. [11:27] I'm going, you need a super big, uh, confluence of meteorology [11:34] nerds. [11:35] And I'm going to go say that's the sixties. [11:38] I mean, people have been doing rain dances for a long time. [11:42] Right. [11:43] Um, and then do you think that the gender naming [11:46] thing will fall away as we try to become less, uh, gender, um, [11:52] bent in our society? [11:54] I feel like we just, I feel like we just thought that up. [11:56] Yeah. [11:57] I think it went from. [11:59] Yeah. [12:00] Good point. [12:01] Yeah. [12:02] It'll all be, um, unisex names, like it'll be a very [12:05] 20 hurricane pads per year now. [12:08] Um, yeah. [12:10] Cause I, my impression, I actually, I don't know. [12:19] I guess you could go either way that a misogynistic culture would name [12:24] all of the hurricanes female, or they would name all of them male. [12:27] Cause they were like, uh, yeah. [12:29] Strong. [12:30] Sure. [12:31] A storm has a big deck. [12:32] Right. [12:33] Um, boats and boats are female and storms are male. [12:35] I mean, right. [12:36] Cause like that's what's coming to dominate the boat. [12:38] Right. [12:39] Okay. [12:40] Yeah. [12:41] Yeah. [12:42] So what's the, [12:43] there's basically no way to not be misogynistic. [12:45] Right. [12:46] That's what I'm saying. [12:47] Have you, have you met America? [12:48] Um, so I'm going to go back. [12:51] What's the earliest hurricane name you can remember? [12:54] I mean, you're saying you're throwing out 1800s, [12:56] but you can't come up with an 1800s name of a hurricane. [12:59] Right. [13:00] Like what about Hugo or Andrew or these are in the nineties, right? [13:04] The eighties. [13:06] Sure. [13:07] I mean, I know, I know they've been doing it during my lifetime. [13:10] I mean, those are the things that I remember, [13:12] the things that happened during my life. [13:15] Oh man. [13:16] Really funny comedian on Netflix. [13:20] And I probably should figure out his name, but, um, the joke was, [13:23] he took his two year old to Disneyland. [13:25] Uh, Disney world or whatever. [13:26] And all his friends were like, [13:28] why are you wasting money on this kid? [13:30] Which has no memories. [13:32] He's like, so that's when I put the kid in a closet and I wake him [13:36] up every morning and ask if he remembers yesterday. [13:38] And if not, I see him. [13:39] And he's like, [13:40] Oh man, I'm a really funny comedian on Netflix and I probably should [13:43] figure out his name. [13:44] And if not, I see him. [13:56] We're off track. [13:59] Coalson on this one. [14:00] I think that naming conventions didn't start until. [14:03] Yeah. [14:04] I'm going to say like the fifties or six. [14:05] Okay. [14:06] So you're going like what? [14:07] 1910. [14:09] And I'm going 1960 and Jason's on board with me. [14:13] Yeah. [14:14] I'm with you on this one. [14:15] That makes a lot of sense. [14:18] Um, what was the question? [14:20] Answer the question. [14:21] So we were asking about hurricane. [14:23] It was like, why do we do it? [14:24] When did we start doing it? [14:25] Okay. [14:26] So it's just the name. [14:27] Well, no, but also what's about why, [14:30] why is a barometric pressure involved? [14:33] I don't understand atmospheric pressure. [14:35] Apparently that's just something I don't get. [14:37] So might need to start another podcast. [14:39] No, because here's my thing. [14:40] Right. [14:41] So like right now I'm living in the, [14:44] in the universe, right? [14:45] I'm living in, I'm sitting in a room. [14:47] There is a certain amount of atmospheric pressure on me. [14:51] Right. [14:52] Just like there would be if I was in water, correct? [14:54] Sure. [14:56] And at sea level, [14:57] that's around a thousand millibars or whatever the hell we decide. [15:01] Yeah. [15:02] Okay. [15:03] So, which is like one Pascal. [15:06] So we know all that. [15:08] But if I go, [15:09] if I go higher in the atmosphere, [15:12] that's more pressure or less pressure. [15:15] Why do I have to wear a spacesuit? [15:16] Is it because my, [15:17] I'm going to explode or, [15:18] or I'm going to melt. [15:19] Oh, what's, what's going on? [15:23] Definitely less pressure as you go up because there's, [15:26] there's, [15:27] because you're getting closer to the edge of the atmosphere. [15:29] Right. [15:30] So there's less air. [15:31] Above. [15:32] Right. [15:33] So why would less pressure be bad for me? [15:36] I feel like it'd be like less stressful. [15:39] Well, that's a, that's a good, [15:40] that's a good joke. [15:42] Less oxygen. [15:43] Right. [15:45] Yeah, exactly. [15:46] Your lungs have to work harder to breathe in more air [15:50] because they're pulling it from a lower density, [15:53] pressure environment. [15:54] Okay. [15:57] And then, [15:58] so I'm sure that you remember us talking about this at some point, [16:02] but like there's always the discussion about, [16:04] so essentially your body is regulating. [16:07] It's pushing out at one Pascal. [16:10] Right. [16:11] All times. [16:12] At all times. [16:13] Right. [16:14] Okay. [16:15] And so if you did go out in space without a space suit, [16:17] would you just explode? [16:18] Like this is definitely a conversation that we had in physics at some [16:21] point. [16:22] Right. [16:23] Well, [16:26] the further I get away from sea level, [16:28] the harder it is to breathe. [16:32] Yeah. [16:33] It's accurate. [16:34] And it's also, [16:36] also tends to be colder. [16:38] Right. [16:39] Hangovers are worse. [16:41] Space hangovers. [16:43] Space hangovers are worse. [16:47] You got to hydrate in space. [16:50] You just got to have a beer and then a water. [16:53] You know, if you don't, if you don't do that, [16:55] you're just kind of really spacing hours. [16:58] So, so do so. [17:01] So if my lungs weren't able to get enough air, [17:08] I feel like it wouldn't explode. [17:10] It would explode. [17:11] It would explode. [17:13] I feel like it wouldn't explode. [17:14] It would shrink. [17:15] So. [17:18] Oh, but you're saying I push out. [17:19] I get it. [17:20] My body is pushing out against. [17:21] Okay. [17:22] Yeah. [17:23] I would definitely explode. [17:24] My eyes would come out of my head. [17:25] And that's definitely something. [17:27] Something that happened in total recall. [17:29] If you'll remember, [17:30] he breaks his space suit and his eyes start bulging out of his head. [17:33] I don't think that that actually happens, [17:35] but it does make for, I mean, [17:37] far be it for me to criticize total recall. [17:41] It's an incredibly scientifically accurate movie. [17:45] Yeah. [17:47] Martians definitely have three boobs. [17:48] That's all I've learned. [17:50] And if they don't again, [17:51] why am I even going there? [17:53] Bad hangovers. [17:57] I think I have an answer for the naming. [18:00] Okay. [18:01] So in the early fifties, [18:02] the National Hurricane Center started naming storms in the Atlantic Ocean [18:09] by the phonetic alphabet, [18:13] according to a phonetic alphabet, [18:17] and they list Abel, Baker, Charlie. [18:19] So it wasn't the sexy names that we get today. [18:27] Okay. [18:28] So in 53, [18:30] they wanted to avoid using repetitive names. [18:36] It just says in the early fifties. [18:38] So every year they were doing Abel, Baker, Charlie. [18:41] Exactly. [18:42] Yeah. [18:43] And then they're like, yeah, this is dumb. [18:44] Let's change that. [18:45] And so then they started giving them all female names, [18:48] but again, an alphabet border. [18:50] I guess I was wrong on that prediction. [18:54] And then in 78, 79, [18:55] the system was revised again to include both female and male hurricane names. [19:01] You have to have a wind speed of 39 miles per hour or more [19:11] to get a tropical storm named. [19:15] So the first ever daily weather forecasts were published in the Times [19:20] on August 1st, 1861. [19:24] But those were hyper accurate. [19:29] I guess hurricanes are super hot. [19:32] So they... [19:34] That makes sense because they're a ton of energy, right? [19:37] Yeah, exactly. [19:40] But the eye is super low pressure. [19:45] Is that what's happening? [19:46] The eye is super low pressure is what I'm reading. [19:48] Yeah. [19:49] Because as the warm air comes in, [19:50] it rises up and then that creates a low pressure center. [19:53] That creates a cyclone action. [19:55] Right. [19:56] Gotcha. [19:58] And then I think Coalson is kind of right. [20:01] Since it's so warm, [20:03] it's like bringing in air from other places or whatever, [20:08] like in front of it, the same way that there's... [20:11] The center of it is low pressure. [20:13] That sort of cone around it is also low pressure, I think. [20:18] Yeah. [20:19] Because I guess you got to think about it in three dimensions, [20:21] which I never do, right? [20:23] No. [20:24] Because air is moving up and down and swirling around. [20:27] It's just a satellite image, two-dimensional satellite image. [20:31] Ah, gotcha. [20:33] I am disturbed by all of the retired names. [20:37] This is a very long list. [20:39] That means there's too many hurricanes. [20:41] You can't have a Hurricane Agnes ever again. [20:50] Or a Hurricane Anita. [20:52] Or Audrey. [20:53] Come on, Audrey's a lovely name. [20:55] Apparently that was the 19th hurricane. [20:58] 1957 Audrey hurricane. [21:03] Harvey. [21:06] Hugo. [21:08] Irene. [21:10] Ivan. [21:12] Wilma. [21:15] Yeah, boy, there's a bunch of names off the list. [21:17] They're going to have to start coming up with some weird-ass hipster names, [21:21] like, you know, Apple or, you know... [21:28] Brooklyn. [21:30] Those are both still available. [21:33] Oh, but unfortunately, Hurricane Bob is taken. [21:39] 1991 Hurricane Bob. [21:46] So the lowest millibar per inch ever recorded was 870 [21:52] on October 12, 1979 in the West Pacific. [21:57] And its name was Tip. [22:01] Tip. [22:02] Tip. [22:03] So, and that suggests that it's the strongest hurricane we've ever had on record then? [22:08] Potentially. [22:09] They're definitely closely related. [22:10] Yeah. [22:11] That's what I'm reading. [22:12] Yeah, I mean, because if the way that we've kind of uncovered this is if [22:16] the lower the barometric pressure, the stronger the storm. [22:23] Right? [22:24] Isn't that what we've kind of decided? [22:27] Right. [22:28] I mean, potentially the more air it can, you know, [22:30] suck in and then kick out, the larger the cyclone you could create. [22:36] You don't need to watch the Weather Channel. [22:38] You got us. [22:43] Typhoon tips had 190 mile per hour winds. [22:49] Okay, so that's really impressive. [22:52] Patricia officially holds the record for the strongest winds [22:55] attributed to a tropical cyclone with 185 knots, which is 213 miles per hour. [23:01] Wow. [23:02] Sustained at its peak strength, central pressure, 872 millibars. [23:10] So I think a lot of it has to do with how long you can sustain those [23:13] pressure differentials, right? [23:15] For sure. [23:16] But there was there was someone recently in a position of power who [23:22] just wanted to like nuke hurricanes because he thought it would help. [23:27] It works. [23:28] But the reality is that there's so much energy in them that the [23:32] energy of a nuclear weapon like isn't very much by comparison. [23:38] Oh, wow. [23:39] Like that's the big problem is that hurricanes are just way more [23:43] power than a nuclear weapon. [23:45] I mean, is that the only problem? [23:50] I mean, no, no, it's not. [23:55] Well, nicely done, team. [23:59] I feel like we've nailed that. [24:01] Can you go? [24:02] Can you take this back to Jill and explain it to her or do you [24:05] just have to play this tape? [24:08] I will just play the tape. [24:10] I'll try to explain it to her, but she's probably already [24:14] googled it by now. [24:18] I wouldn't trust us either, honestly. [24:20] May have to add some footnotes after she corrects everything [24:22] that we just said. [24:23] That's right. [24:24] That's right.
