Flying into the Eye of a Storm

The Master Chef of Kids’ Hands-On Science

Dr. Hugh Willoughby, of Florida International University, was one of the first meteorologists to ever fly into the eye of a hurricane.  Now the job is done by the Hurricane Hunters—a team of pilots, navigators and meteorologists who fly into these dangerous storms to help keep us safe.  Here’s what I learned when I interviewed Hugh Willoughby:

What is a hurricane eye?

Hurricanes are circular storms so the wind blows around in a circle. The eye is the center of a hurricane.  If a circular storm doesn’t have an eye, it is not a hurricane—it’s a tropical storm.  The eye is surrounded by a ring of clouds called the eyewall. Within the eye, there is a calm area that is cloudless all the way up to space.   The winds are strongest just at the inner edge of the eyewall, which is composed of violent thunderstorms with strong updrafts and downdrafts.   The hurricane pinwheels out from the eyewall as spiral bands of wind and rain, which stretch for miles.  When a hurricane’s eye passes over land, the storm suddenly stops and the sun comes out.  But the relief is short-lived as the other side of the storm soon slams into the area.

How do Hurricane Hunters help us?

Hurricane Hunters fly into the eye of hurricanes that are heading towards our shores to help predict where the storm will make landfall.  On every mission they must find the center of the storm at least twice and at most four times over a period of several hours because the change in position of the center of the eye tells us the direction the storm is moving and how fast it is moving. They also drop packages called dropsondes that contain measuring instruments for air pressure, humidity, and wind speed at the eyewall.  These measurements tell us the destructive power of the storm or its “category.” During a hurricane season (from June 1 to November 30) the Hurricane Hunters and their fleet of ten airplanes can get data on three storms, twice a day.  So flying into a hurricane’s eye is pretty routine for them.

Is it dangerous?

The planes can easily handle changes in air pressure and wind speeds that create “bumps” and it can be pretty bumpy going through the eyewall.   But, in more than sixty years there have been only four accidents. All on board agree that the view of the eyewall from inside the eye is worth it! The plane has transported them inside nature’s most magnificent amphitheater.

Harvey and Irma have alerted everyone to the dangers of a hurricane. We can predict the course of a hurricane by flying into a hurricane and repeatedly measuring wind speed, humidity, air pressure, and temperature. Here's a video that will give you a taste of what it looks like as you approach an eye wall. It is filmed from a plane penetrating Hurricane Katrina.

When you hear about a Category "3" hurricane, or any other category number, the Saffir-Simpson Scale tells you just what that number means.

Look at the amazing number of instruments contained in a Dropsonde.

Vicki Cobb's latest book, How Could We Harness a Hurricane? shows how the scientific understanding of air, water and energy come together to form hurricanes. It includes lots of hands-on activities that you can do. Engineers look at science and try and figure out ways the steer a hurricane away from populated areas or weaken them. There are lots of questions in the book and some of them don't have answers, yet.

Hopping Ahead of Climate Change

Connecting Scientists and Kids

Earth’s temperatures are getting warmer. In fact, sixteen of the seventeen hottest years on record have occurred since the year 2000. These warmer temperatures are driving larger, long-term changes in our planet’s weather and climate. Scientists refer to these changes as “climate change.”

In a few places, climate change might be welcome, but around the world, warmer temperatures and other changes are leading to a host of problems from rising sea levels to more extreme weather events and the spread of harmful human diseases.

Professor Scott Mills, from the University of Montana, wanted to see how climate change might be affecting one particular animal called the snowshoe hare.

Snowshoe hares live in regions of North America that receive snow every winter. The hares, in fact, change their coat color from brown to white and back again every year. This helps camouflage them against their background—and hides them from the eyes of lynx, owls, and other hungry predators.

  Here’s the thing: snowshoe hares can’t choose when they molt, or change their coat color. Molt timing is controlled by their genes, which are part of the DNA inside their bodies. If a hare’s genes make it molt to white in October, but snow doesn’t fall until December, the hare will stick out like a light bulb against the brown earth. And that’s a problem. Why? Because almost everywhere on earth, the length of time with snow on the ground is growing shorter and shorter.

  To find out if shorter winters might harm hare populations, Scott and his team spent three years tagging and following hares. They measured how many were born, how many died, and what they died from. They also recorded whether the hares were matched or mismatched against their backgrounds.

  They discovered that predators killed mismatched hares significantly more often than hares whose coats match their backgrounds. Scott and his team also calculated that over the next one hundred years, this greater mortality, or death rate, could lead to the decline or disappearance of many snowshoe hare populations.

  The good news? Different hares molt at different times. This may help some hare populations adapt to shorter winters and longer periods without snow.

  Hares are not the only animals affected by shorter winters. More than twenty species of animals including lemmings, weasels, hamsters, and Arctic foxes change their coat colors every year. Scott’s research helps us predict what might happen to these animals—and decide what we can do to protect them.

Scott’s discoveries about Montana snowshoe hares, together with experts’ predictions about our future climate, indicate that hares will be mismatched between 5-½ and 10 weeks by the end of this century.

Before tagging and putting a radio collar on a snowshoe hare, Professor Mills and his team must weigh and measure it.

This snowshoe hare has been tagged and fitted with a radio collar—and is now ready to help scientists learn more about snowshoe hare survival.

Besides serving as popular prey for predators, snowshoe hares are irresistibly cute. This is a young hare, also called a leveret.

What's the Biggest Number?

3/13/2023

David M. Schwartz
The amazing, engaging, math exponent.

Can you put into words what these equations are telling you?

Think of a big number. How about one million? It's a thousand thousand. That's a lot. If you counted nonstop to a million, it would take you about 23 days.

A million is small compared to a billion, which is a thousand million. Want to count that high? You'll be at it for 95 years. But a trillion makes a billion look puny. A trillion is a thousand billion (or a million million). Counting that high would take you 200,000 years. Have fun!

Of course trillion is not the biggest number. There's quadrillion, quintillion, sextillion, septillion, octillion, nonillion, decillion and more. Each is a thousand of the previous one. There's even a humongous number called vigintillion, a one with 63 zeros.

But vigintillion is a shrimp compared to a googol. Googol? Notice how it's spelled: G-O-O-G-O-L, not G-O-O-G-L-E. The number googol is a one with a hundred zeros. It got its name from a nine-year old boy. A googol is more than all the hairs in the world. It's more than all the grass blades and all the grains of sand. It's even more than the number of atoms in the universe. Astrophysicists estimate the number of atoms to be a one with 82 zeros. You'd need to add 18 more zeros to get to a googol.

Incidentally, a few years ago, the two men who had invented a powerful new internet search engine decided to name their website and company for the gigantic number googol. But they spelled it wrong. That's why the company Google is spelled with an L-E. But the number googol is still spelled with an O-L.

Googol is so large that it's practically useless, but the boy who named it came up with a name for an even bigger number, "googolplex." A googolplex is a one with a googol zeros. There isn't enough ink in all the pens of the world to write that many zeros but feel free to give it a try.

So is googolplex is the biggest number? What about a googolplex and one? Two googolplex? A googolplex googolplex? Any number you say, I can say one bigger.

I hear you asking, "What about infinity? Isn't that the biggest number?" Sorry, but infinity isn't a number. A number specifies an amount and infinity is no amount. It means "goes on and on forever."

And that's what numbers do. They go on and on forever. Infinity is not a number but numbers are infinite.

Think you're too old for an alphabet book? You'll think again if you check out a sampling from David M. Schwartz's: B is for Binary, F is for Fibonacci, P is for Probability... You can see that this is an ABC book unlike any other. For more information, click here.

Vincent Van Gogh and the Case of the Missing Ear

Jan Greenberg
celebrates the arts
(with Sandra Jordan)

Self-portrait with Bandaged Ear, 1889, with an easel and a Japanese print in the background. The artist collected these prints when he lived in Paris

Who was Vincent Van Gogh? Ask around and most people come up with the same answer. He was the famous artist who cut off his ear. What is the truth about Vincent Van Gogh? Was he a great painter because he led a life of extremes? Or was he a great painter despite his disordered life?

Several years before his death, he began to experience seizures and blackouts during which he heard voices and behaved strangely. Are the pulsating spirals, undulating lines and dizzying stars of his late paintings what he saw when he was having an attack? Or are they the result of a style he developed painstakingly through years of hard work?

In 1888, Vincent moved to Arles in the south of France. He planned to establish an artists’ commune where his friends could live together to create a new direction in painting. Vincent persuaded the artist Paul Gauguin, who was desperate for money, to move to Arles to help him. Vincent also was lonely.

For two months Gauguin lived in the Yellow House Vincent had lovingly filled with paintings hoping to impress his friend. Gauguin bossed Vincent around and criticized his artwork. Eventually, when Gauguin sold a few paintings, he threatened to abandon Vincent.

Finally, on Christmas Eve, after a quarrel at dinner, Gauguin stalked off into the streets. Vincent followed him. What happened next is unclear, but Vincent returned to the Yellow House alone and cut off his earlobe (not the whole ear) with a razor. Vincent couldn’t remember the details of this terrible night. But when he was discharged from the hospital a few weeks later, he went right back to work.

There have been many theories about Vincent’s condition. The theory most generally accepted is that he suffered from epilepsy, a disease that could have caused his seizures and hallucinations and for which there was no medication. In Vincent’s case, another reason for his “attacks” might have been his habit of drinking absinthe, an alcoholic drink popular in 19th century France. It contains a strong nerve poison, now illegal in most countries.

Today many popular performers advertise how dangerous and extreme their lives are by writing shocking lyrics and acted outrageously on stage. They are mimicking the lives of artists such as Van Gogh. But he was not advertising or pretending. He just wanted to be useful—to make art that would last. His glorious paintings are the result of his discipline and dedication, despite the turmoil of his life.

Vincent Van Gogh, The Yellow House, 1888, oil on canvas, Van Gogh Museum, Amsterdam. This is the house at 2 Place Lamartine, Arles, France, where, on May 1, 1888, Vincent van Gogh rented four rooms and where Paul Gauguin lived for nine weeks from late October, 1888. The left wing housed a grocery (French: Comestibles, inscribed on the signboard over the marque). Van Gogh indicated that the restaurant, where he used to have his meals, was in the building painted pink close to the left edge of the painting.

If you are interested in finding out more about Vincent Van Gogh, Jan Greenberg and Sandra Jordan have written an award-winning book on the subject. Click here for more information.
