## Transcript

[0:00] SPEAKER_00: Welcome to Science Is Not Boring by kidoply.com.
[0:03] SPEAKER_00: I'm Mira! And I'm Finn! Before we look up at the sky today, we have a massive shout-out.
[0:10] SPEAKER_00: This one goes to Penny, who is five years old and lives in New Mexico.
[0:15] SPEAKER_01: Hi Penny! Thanks for asking us to do an episode all about clouds and how they got their names.
[0:21] SPEAKER_01: New Mexico has some incredibly beautiful skies, so great question.
[0:25] SPEAKER_00: That's right! This episode is just for you, Penny.
[0:29] SPEAKER_00: And Finn, I have a mind-blowing question to start us off.
[0:33] SPEAKER_00: Okay, I'm ready.
[0:35] SPEAKER_00: Hit me.
[0:36] SPEAKER_00: When you look at a fluffy white cloud on a sunny summer day, it looks like a giant cotton ball floating peacefully in the sky, right?
[0:44] SPEAKER_00: How much do you think one of those fluffy clouds actually weighs?
[0:48] SPEAKER_01: Hmm.
[0:49] SPEAKER_01: It literally floats on thin air, so it must be super light.
[0:54] SPEAKER_01: Like maybe£10?
[0:56] SPEAKER_01: Or£20?
[0:58] SPEAKER_01: Try 1.1 million pounds.
[1:02] SPEAKER_01: What?
[1:02] SPEAKER_01: No way! That's impossible! How can something that weighs over a million pounds just float up there without crashing down on us?
[1:11] SPEAKER_00: That is exactly what we are going to find out today.
[1:14] SPEAKER_00: We're talking about the secret science of clouds, the brilliant man who first gave them their names, and the wild, extreme weather hidden inside them.
[1:23] SPEAKER_01: One million pounds?
[1:25] SPEAKER_01: I am so ready for this.
[1:27] SPEAKER_01: Let's go! Okay, I still can't stop thinking about a million pound cloud.
[1:31] SPEAKER_01: What is that an animal weight?
[1:34] SPEAKER_00: Well, 1.1 million pounds is about the same weight as 100 full-grown adult elephants.
[1:42] SPEAKER_01: Wait, so when I'm eating a sandwich at the park, there are a hundred invisible elephants floating right over my head.
[1:49] SPEAKER_01: What keeps them from falling on us?
[1:51] SPEAKER_00: Don't worry, clouds are made up of trillions of tiny microscopic water droplets.
[1:57] SPEAKER_00: Gravity still pulls them down, but air resistance and updrafts easily keep them afloat because they are so small and light.
[2:05] SPEAKER_00: It takes a million of those droplets just to make one single raindrop.
[2:11] SPEAKER_00: So they just spread out all over the place.
[2:13] SPEAKER_00: Exactly.
[2:14] SPEAKER_00: A typical cumulus cloud takes up about one billion cubic metres of space.
[2:20] SPEAKER_00: The air in the cloud is less dense because it contains water vapour, which is lighter than dry air and is warmer than the surrounding air.
[2:29] SPEAKER_00: Plus, rising warm air currents push from below, acting like an invisible hand holding it up.
[2:36] SPEAKER_01: Phew.
[2:37] SPEAKER_01: Invisible air hands for the wind.
[2:39] SPEAKER_01: But Penny wanted to know how they got their names.
[2:42] SPEAKER_01: Did scientists always know what to call them?
[2:45] SPEAKER_00: Not at all.
[2:47] SPEAKER_00: For hundreds of years, scientists thought clouds were simply too chaotic and hard to name, because they constantly change shape.
[2:54] SPEAKER_00: They just describe them by their colour, like dark or light.
[2:59] SPEAKER_00: That's so confusing.
[3:01] SPEAKER_01: Hey, look at that greyish-white swirly thing over there.
[3:05] SPEAKER_00: Exactly! But then, in December of the year 1802, a young amateur meteorologist in London named Luke Howard changed everything.
[3:16] SPEAKER_00: Luke Howard?
[3:17] SPEAKER_00: Was he a famous weather professor?
[3:19] SPEAKER_00: Nope.
[3:20] SPEAKER_00: His actual day job was a pharmacist and a manufacturing chemist.
[3:24] SPEAKER_00: He just loved watching the weather in his spare time, taking careful notes every single day.
[3:30] SPEAKER_00: A pharmacist who looked at the sky?
[3:33] SPEAKER_00: What did he do?
[3:34] SPEAKER_00: He stood up in front of a respected science club in London called the Askesian Society.
[3:40] SPEAKER_00: He had a brilliant idea.
[3:42] SPEAKER_00: What if clouds weren't just random blobs?
[3:45] SPEAKER_01: What if they belonged to specific families?
[3:48] SPEAKER_01: So Luke Howard just pointed at the sky and started naming them.
[3:53] SPEAKER_00: Kind of! He used Latin words to describe the three main shapes he saw.
[3:58] SPEAKER_00: The first one he called cumulus.
[4:01] SPEAKER_00: Cumulus?
[4:02] SPEAKER_01: That sounds familiar.
[4:04] SPEAKER_01: What does it mean?
[4:05] SPEAKER_00: In Latin, cumulus means heap or pile.
[4:09] SPEAKER_00: These are the fluffy, flat-bottomed clouds that look like heaps of mashed potatoes floating in the sky.
[4:15] SPEAKER_01: The hundred elephant clouds.
[4:17] SPEAKER_01: I love those.
[4:18] SPEAKER_01: What was the next one?
[4:20] SPEAKER_00: Next was stratus, which means layer.
[4:23] SPEAKER_00: Have you ever woken up early and the whole sky is just a thick, flat, grey blanket that blocks out the sun?
[4:30] SPEAKER_01: Ugh, yeah, those are the gloomy days.
[4:34] SPEAKER_00: Right.
[4:35] SPEAKER_00: Stratus clouds are essentially huge layers of fog that float high up.
[4:40] SPEAKER_00: But Luke Howard's third cloud type is my absolute favourite.
[4:44] SPEAKER_00: He called it cirrus.
[4:46] SPEAKER_00: Cirrus?
[4:47] SPEAKER_00: That sounds fancy.
[4:48] SPEAKER_00: What does it mean?
[4:49] SPEAKER_00: It means curl of hair.
[4:51] SPEAKER_00: They are those really thin, delicate, wispy streaks that look like someone painted them with a tiny brush.
[4:58] SPEAKER_01: Why are they so thin and wispy compared to the giant puffy heap ones?
[5:02] SPEAKER_00: Because of how incredibly high up they are.
[5:05] SPEAKER_00: Cirrus clouds form between 20,000 and 40,000 feet above the Earth.
[5:11] SPEAKER_01: 40,000 feet?
[5:13] SPEAKER_01: That's higher than most commercial aeroplanes fly.
[5:16] SPEAKER_00: Exactly! Up in that part of the atmosphere, the temperature drops way below freezing.
[5:22] SPEAKER_00: It can easily reach minus 40 degrees.
[5:25] SPEAKER_00: So cirrus clouds aren't made of liquid water droplets.
[5:28] SPEAKER_00: They are made entirely of tiny, shiny ice crystals.
[5:33] SPEAKER_01: So when you see those wispy hair clouds catching the sunlight, you're actually looking at billions of floating ice mirrors.
[5:40] SPEAKER_01: Science is so cool.
[5:41] SPEAKER_01: But wait, what about the scary clouds?
[5:44] SPEAKER_01: The dark, menacing ones that shoot lightning, boom with thunder, and dump freezing rain on us.
[5:50] SPEAKER_01: Did Luke Howard name those two?
[5:52] SPEAKER_01: He sure did!
[5:53] SPEAKER_00: He used the Latin word nimbus, which translates to dark cloud or rainstorm.
[6:00] SPEAKER_01: Rainstorm?
[6:01] SPEAKER_01: That sounds intense.
[6:02] SPEAKER_01: A nimbus cloud's their own separate thing?
[6:05] SPEAKER_00: Actually, Luke Howard realised you could mix the names together.
[6:09] SPEAKER_00: Later, scientists used his system, and in 1880, Philip Weilbach decided a fluffy cumulus heap bringing a rainstorm becomes a cumulonimbus cloud.
[6:20] SPEAKER_01: Cumulonimbus?
[6:22] SPEAKER_01: A heaping rainstorm?
[6:24] SPEAKER_00: How big do those storm clouds get?
[6:27] SPEAKER_00: Absolutely huge, Finn.
[6:29] SPEAKER_00: A cumulonimbus thunderstorm cloud can grow vertically, like a giant skyscraper.
[6:35] SPEAKER_00: They can stretch over 60,000 feet tall.
[6:38] SPEAKER_01: 60,000 feet?
[6:40] SPEAKER_01: That's more than 11 miles straight up into the sky.
[6:44] SPEAKER_00: Yes, they are like massive atmospheric beasts carrying millions of tons of water.
[6:50] SPEAKER_00: Inside them, fierce winds called updrafts and downdrafts are ripping up and down at super speeds.
[6:57] SPEAKER_00: They crash small ice particles and tiny hail together in the dark to create huge sparks of lightning.
[7:05] SPEAKER_01: That is wild.
[7:06] SPEAKER_01: I bet the scientists at that London Club were totally blown away by his ideas.
[7:11] SPEAKER_00: They were! Luke Howard published his cloud essay in 1803, and it changed atmospheric science forever.
[7:18] SPEAKER_01: Because before that, people couldn't really track the weather properly across different countries, right?
[7:24] SPEAKER_00: Exactly! By giving clouds universal Latin names, scientists all over the world could write down exactly what they saw in the sky.
[7:32] SPEAKER_00: If someone in France saw a cirrus cloud, someone in America knew precisely what it looked like and what altitude it was at.
[7:41] SPEAKER_01: All thanks to a brilliant pharmacist who loved looking up at the sky.
[7:44] SPEAKER_01: So we have the fluffy heaps, the gloomy layers, the icy hair streaks, and the giant towers of rainstorms.
[7:54] SPEAKER_01: Are there any other weird clouds we should know about?
[7:57] SPEAKER_00: Oh, there are some incredibly strange ones.
[8:00] SPEAKER_00: Have you ever heard of a lenticular cloud?
[8:03] SPEAKER_01: Lenticular?
[8:04] SPEAKER_01: No, that sounds like a tiny type of bean you put in soup.
[8:09] SPEAKER_00: Well, lenticula actually means lens-shaped.
[8:12] SPEAKER_00: But people usually think they look like giant, perfectly stacked pancakes.
[8:17] SPEAKER_00: Or, better yet, massive alien UFOs hovering in the sky.
[8:22] SPEAKER_01: UFO clouds?
[8:24] SPEAKER_00: Where in the world do you find those?
[8:26] SPEAKER_00: They usually form near big mountain ranges.
[8:29] SPEAKER_00: When superfast winds, sometimes blowing over 50 miles an hour, slam into the side of a tall mountain, the air is forced straight up.
[8:39] SPEAKER_01: So the wind rushes over the mountain peak like a giant invisible ocean wave.
[8:44] SPEAKER_01: Exactly!
[8:45] SPEAKER_00: And at the very top of that invisible wave of air, the moisture instantly condenses into a huge, smooth, saucer-shaped cloud.
[8:54] SPEAKER_01: But if the wind is blowing at 50 miles an hour, doesn't the cloud just blow away across the sky?
[9:00] SPEAKER_00: That's the craziest part! Lenticular clouds are stationary.
[9:04] SPEAKER_00: They just hover in one exact spot, totally still, while the ferocious wind howls right through them.
[9:12] SPEAKER_00: The cloud is constantly forming at the front edge and evaporating at the back edge.
[9:17] SPEAKER_01: So it's basically a water vapor treadmill in the sky.
[9:20] SPEAKER_01: If I saw that, I would definitely think it was an alien spaceship.
[9:25] SPEAKER_00: A lot of people have actually called in UFO sightings because of them.
[9:29] SPEAKER_00: But really, clouds are just nature's way of painting the weather.
[9:33] SPEAKER_00: If you see high wispy cirrus clouds, warm air might be moving in.
[9:38] SPEAKER_00: If you see towering cumulonimbus, grab an umbrella and get inside.
[9:43] SPEAKER_00: Alright, Finn, it's time for the quiz! Are you ready to test your weather knowledge?
[9:48] SPEAKER_01: I hope my brain doesn't evaporate like a lenticular cloud on a treadmill.
[9:52] SPEAKER_01: Let's do this! First question.
[9:55] SPEAKER_00: What was the name of the amateur meteorologist who first named the clouds in 1802?
[10:04] SPEAKER_00: Next one.
[10:05] SPEAKER_00: We talked about heavy clouds today.
[10:07] SPEAKER_00: How much does an average fluffy cumulus cloud weigh?
[10:14] SPEAKER_00: Question 3.
[10:16] SPEAKER_00: Luke Howard used Latin to name clouds.
[10:19] SPEAKER_00: What does the word cumulus mean?
[10:24] SPEAKER_00: Here's number four.
[10:26] SPEAKER_00: Which type of high altitude clouds are completely made of tiny ice crystals?
[10:35] SPEAKER_00: Last question.
[10:37] SPEAKER_00: What do we call the weird stationary clouds that look like giant alien UFOs over mountains?
[10:46] SPEAKER_00: Great job! Let's see how you did.
[10:50] SPEAKER_00: The first answer is his name was Luke Howard.
[10:54] SPEAKER_00: For question two, an average cumulus cloud weighs an incredible 1.1 million pounds, or about a hundred elephants.
[11:04] SPEAKER_00: Number three, the answer is cumulus means heap or pile.
[11:09] SPEAKER_00: Question four.
[11:11] SPEAKER_00: Cirrus clouds are the high, wispy ones made entirely of ice crystals.
[11:16] SPEAKER_00: And the final answer is those UFO-shaped ones are called lenticular clouds.
[11:22] SPEAKER_01: Wow, I am literally never going to look at the sky the same way again.
[11:27] SPEAKER_01: Every single cloud has a secret story.
[11:30] SPEAKER_01: From the icy streaks to the hundred elephant fluffballs.
[11:35] SPEAKER_00: That's the magic of science.
[11:37] SPEAKER_00: Speaking of magic, we'd absolutely love it if you could leave our podcast a five-star review.
[11:43] SPEAKER_00: Just scroll down on your listening app and tap those five stars.
[11:47] SPEAKER_01: Yeah, you can even tell us in your review which cloud is your favourite.
