APOD: A Waterspout in Florida (2013 Jul 17)

Post by APOD Robot » Wed Jul 17, 2013 4:07 am

Image A Waterspout in Florida

Explanation: What's happening over the water? Pictured above is one of the better images yet recorded of a waterspout, a type of tornado that occurs over water. Waterspouts are spinning columns of rising moist air that typically form over warm water. Waterspouts can be as dangerous as tornadoes and can feature wind speeds over 200 kilometers per hour. Some waterspouts form away from thunderstorms and even during relatively fair weather. Waterspouts may be relatively transparent and initially visible only by an unusual pattern they create on the water. The above image was taken earlier this month near Tampa Bay, Florida. The Atlantic Ocean off the coast of Florida is arguably the most active area in the world for waterspouts, with hundreds forming each year. Some people speculate that waterspouts are responsible for some of the losses recorded in the Bermuda Triangle.

Nice picture, but what does it have to do with astronomy? Yes, we've seen weather phenomenon on other planets, such as a dust devil on Mars; but, seriously, what is the point of talking about a water spout? Have we actually verified that there is an ocean on a nearby planet or moon? And that it has water spouts, or methane spouts, or something spouts? A weather satellite picture is more "astronomy" that this because at least it is of extraterrestrial origin. Though one could argue that since the satellite is captive in the Earth's gravitational field, it is not extraterrestrial. At least it is taken from space and maybe you could say something witty like "Don't you how those extraterrestrials sure would like to get their hands on those weather satellite signals!" Or maybe change your name to "Awesome Picture of the Day."

Well, you certainly put a lot of thought into it. That's exactly why APOD sometimes deviates from its usual subject. It gets people interested and talking about stuff.

Cor, 'at's WICKED, mate!!!

Go search videos of waterspouts. Some are amazing. I remember a "small" one in Florida that was moving in a harbor. Fascinating. It was not really so much a Tornado, as a "water devil"....

"What does this have to do with Astronomy?"....well....weather is not only a planetary phenomena...The Sun has "weather"...there are even Space Weather and Solar Weather Observatories. So...Planet Earth Weather...is an "Astronomical Phenomena"...I suppose....
It is like that picture a few weeks ago...."Four Planet Sunset" and you see Jupiter, Venus, and Mercury.....where is the fourth planet then?????? Well....not to give it away....BUT IT WAS EARTH!!!!! The landscape is part of the Planet Earth. So, it was a trick question. So...Earth Weather as Astronomy....I know, I know...I didn't make it up....it does give you a chance to see something you might not otherwise...and that can be a good thing. After all....IF YOU KEEP LOOKING UP.....YOU STUB YOUR TOE, BREAK YOUR ANKLE AND FALL....CRACK YOUR HIP AND THERE YOU ARE!!!!!!! So...look around and even down sometimes. :D

Does it not occur at an interface ( side) of two opposing wind direction.

What's fascinating to me is that the small ripples in the water indicate that there is very little wind along the surface. Yet, as you indicate, waterspouts and tornadoes can have wind speeds up to 200 mph.

The cloud into which the spout leads appears to be a Fibonacci spiral in shape. Is that possible, or just the impression of a photo of a moment in time?

How does that change the Atlantic Ocean off the coast of Florida being the most active area for waterspouts? I saw nowhere in the article where it said Tampa Bay is on the Atlantic Coast. Nor did it say Tampa Bay was in the Bermuda Triangle.

Where are all the “waterspout” chasers in their boats? When it happens on land it’s a major tourist attraction. I’m surprised the researchers are not boating little remote “Dorothy-like” devices, as in “Twister”, into the spout to get data. It would be a lot easier than truckin’ across the corn fields trying to find a spot in front of one. Especially if they happen there quite often.

That probably only happens in the movies. You can tell where I get my information. Next thing I’ll be suggesting is to use drones.

<<Spira mirabilis, Latin for "miraculous spiral", is another name for the logarithmic spiral Image. Although this curve had already been named by other mathematicians, the specific name ("miraculous" or "marvelous" spiral) was given to this curve by Jacob Bernoulli, because he was fascinated by one of its unique mathematical properties: the size of the spiral increases but its shape is unaltered with each successive curve, a property known as self-similarity. The spiral has the property that the angle Φ between the tangent and radial line at the point is constant. This property can be expressed in differential geometric terms as cotan(Φ) = b. Possibly as a result of this unique property, the spira mirabilis has evolved in nature, appearing in certain growing forms such as nautilus shells and sunflower heads. Jacob Bernoulli wanted such a spiral engraved on his headstone along with the phrase "Eadem mutata resurgo" ("Although changed, I shall arise the same."), but, by error, an Archimedean spiral was placed there instead.>>

Excerpted from the book Storm Kings by Lee Sandlin. ©2013 Lee Sandlin.

<<One night in the summer of 1749, a waterspout appeared in the Mediterranean Sea just off the coast of Italy. This wasn’t an unprecedented event. Waterspouts had always been seen in the Mediterranean. The Roman writer Pliny the Elder, in his Natural History, mentioned the mysterious pillars of water that sometimes materialized out of nowhere in the open sea and overturned boats. But for the most part, these waterspouts were remote and vague apparitions—white writhing snakes that danced in the heat of a blue afternoon and vanished before anyone got too close. The 1749 waterspout was a pitch-black monster crowned with lightning that came roaring from the dark sea after midnight and crashed its way onshore.

The news of this strange visitation caused a panic throughout the region. The spout was almost universally believed to be a sign of the apocalypse. The pope was one of the few skeptics, but he kept his opinion to himself. In order to calm the populace, he announced that he was calling upon a well-regarded expert to investigate the incident and issue a public report. The expert was the most famous natural philosopher in Italy, Father Ruder Boscovich. Father Ruder was a Croatian raised by the Jesuits of Rome. His specialty was astronomy, a subject in which he had made several major discoveries. But the pope thought of him more as an all-purpose authority on anything scientific or technical. Summoned to investigate the waterspout, Father Ruder set to work at once. He inspected the trail of ruin. He interviewed survivors and eyewitnesses. He did some research among the records of unusual meteorological events in the vast Vatican library. Then he wrote a detailed monograph laying out his investigations and conclusions. The work only took him a few months, and his monograph was printed and on sale by the end of the year—a fast turnaround time in those days for a two-hundred-page book. The title was On the Whirlwind During the Night of June 11– 12 (Sopra il turbine che la notte tra gli XI e XII giugno). Because of the speed of its composition, it was a fairly slapdash piece of work. While people tended to believe that waterspouts were phenomena of the deep waters of the Mediterranean, the historical records were clear that they did sometimes appear in the shallows off the coasts, and there had been a few documented cases of waterspouts coming ashore. His conclusion was that this was a rare but not unprecedented natural occurrence, and certainly not a sign of the apocalypse.

Copies of the Review began arriving in Benjamin Franklin’s mail, with cover letters asking what he made of it. As Franklin read through these stories, he very rapidly fashioned a theory; he tended to arrive at his theories in a great rush or not at all. The prevailing belief then was that a waterspout was a hollow pillar of water, rising up out of the sea or descending like a waterfall from the clouds. (The Hebrew word for “waterspout,” as used in the book of Psalms, could also be translated as “waterfall.”) Franklin immediately realized that this was physically impossible. The tube of the waterspout simply couldn’t be made out of water. Water is extremely heavy—so heavy that no force known in nature could raise or sustain such a large body of it in midair. So this meant that the solid appearance of the spout had to be an illusion. The spout, Franklin believed, was in fact an ascending column of air, and it only appeared to be made of water because a fog of water vapor was condensing around it as it rose.

Franklin then had a second and odder realization. If the spout was air and not water, then there was no necessary reason for it to be confined to seas and oceans. It could, at least in principle, appear over land as easily as it did over water. In the Bible there were many references to mysterious whirlwinds and columns of smoke (one of them had led Israel to the promised land). But Franklin wanted evidence that was modern and unequivocal.

He found his first piece of evidence deep within the archives of the Philosophical Transactions. In the volume for the year 1703, there had appeared an account by an English minister named Abraham De la Pryme of something he had witnessed over the Yorkshire countryside. De la Pryme called it “one of those strange works of nature called spouts, or rather hurricanes.” He described it as “a great circumgyration or whirling, which made a noise somewhat like the motion of a millstone. Ever and anon it darted down out of itself a long spout, in which I observed a motion like that of a screw.” This spout had swept through the countryside, doing minor damage to village rooftops, and had vanished as mysteriously as it had come. This was clearly a whirlwind over land, just what Franklin was looking for. Maybe it was an extraordinarily rare phenomenon, but here was plain evidence that there existed a violent whirlwind on land identical to a waterspout at sea. What caused it? What sustained it? Where was it to be found? Franklin couldn’t begin to imagine the answers to any of these questions. He didn’t even know what the thing should be named. Sometimes he referred to his quarry as a landspout. Other times he simply called it a whirlwind.

Franklin believed that there had to be some sort of near vacuum in the heart of the storm that was drawing the winds into it at great speed. But with no evidence to suggest how this vacuum might come into existence and no theory of how it could sustain itself, Franklin was at a loss to explain the hows and whys of spouts on land or sea. He was at a dead end. In 1754, he wrote to John Perkins (one of those who’d originally sent him the magazine article about the Rome waterspout): “I am now not much nearer a conclusion in the matter of the spout than when I first read your letter.”

In the spring of 1754, Franklin was in Maryland. He was visiting a friend named Tasker; in his letters he usually called him “the excellent Colonel Tasker.” Tasker was a gambler and a breeder of thoroughbred horses, which was not necessarily Franklin’s usual company, but Tasker was also one of the most well-connected men in the state. The Taskers were considered the cream of the Maryland aristocracy.

Tasker invited Franklin and his son William to stay with him at Belair House, his great family estate in the hilly depths of the countryside. On their way, in the middle of a wide, richly flowing landscape of valleys and forested hills, one of the men in the party called a halt. He gestured for everyone to look down into a little vale that opened up to the side of their path. Below was a dusty road winding through the meadowlands. Moving along the road like a bustling traveler was a tight little commotion of air: a newly forming whirlwind.

The whirlwind looked, Franklin later wrote, like “a sugar-loaf”—by which he meant it resembled a funnel (that was the shape that sugarloaves were commonly spun into). The funnel swerved off the road and came sweeping up the hillside toward them. It swelled as it approached; by the time it crested the hill, Franklin guessed, it was around forty or fifty feet high, twenty or thirty feet across at its height, “no bigger than a common barrel” at its base. It moved past them at a walking pace, with an odd, irregular bob and swerve like a spinning top.

Everyone in the party reared back—except for Franklin. He later said that he just couldn’t help himself. He had to urge his horse to a trot, and he went tagging alongside the funnel to see what it would do. He thought of how sailors were supposed to have broken up waterspouts by firing cannons at them, so he tried lashing at the whirlwind with his whip—“without any effect,” he admitted.

Then the whirlwind turned again and meandered off into the trees.

Franklin followed it. He lost sight of the road. The wind was getting louder; the countless rotted leaves of the forest floor were being sucked up into the funnel in a rushing whisper. All around the funnel, the treetops in the woodland interior were bending and snapping in frantic circles. “The progressive motion of the whirl was not so swift but that a man on foot might have kept pace with it,” he later wrote, “but the circular motion was amazingly rapid.” By then, the funnel had turned into a swirling column that appeared to be made entirely out of dead leaves, which were soaring up out of sight in widening spirals.

And it was still gathering strength. Franklin saw that it was now sucking up large dead boughs along with the leaves. That was when he wondered for the first time about his own safety. By that point, Franklin guessed, he’d followed the whirl into the forest for about three-quarters of a mile. His son William, who had been trailing along behind him the whole way, came up alongside.

When William saw that Franklin was hanging back, he urged his own horse forward. The funnel was roaring in the depths of the woods; William boldly pursued it for another half mile. The chase ended when the funnel emerged into the open air of an old cultivated tobacco field, and there unexpectedly melted away into nothingness.

Franklin and William, covered in sweat, their clothes spangled with countless leaves, made their bedraggled way back to the road. The air all around them was filled with a storm of leaves, billowing and drifting and soaring in the gusts. Franklin later noted that the leaves kept falling on them for miles afterward. One of the company then turned to Colonel Tasker and asked if these kinds of whirlwinds were common in Maryland.

“No, not at all common,” Tasker said. “We got this on purpose to treat Master Franklin.”>>

... the Bermuda Triangle

Post by RedFishBlueFish » Wed Jul 17, 2013 8:39 pm

The "Bermuda Triangle" does not, in any meaningful way, exist.

As Mr Kusche's research showed quite convincingly in his 1975 book the whole idea was invented by writers for men's adventure magazines in the 1960s. The triangle is no more real than new-age "energy" (what sort of energy is being posited?) vortices, the Loch Ness monster or the moon-landing-as-hoax conspiracy delusion.

That said: Quite a remarkable picture - thanks for sharing it; however, too bad APOD could not present this without pandering to the endless demand for mysterious or supernatural hogwash.

Who doesn't like a good mystery, though? For as long as I've been following APOD, they've never tried to explain anything supernaturally. It's always either a statement about what we know or what we don't know. They do quite often ask questions and leave one to speculate, though. Anyway, I think you're being unfair here. Anyone can fall for an urban legend. Heck, I didn't know that the Bermuda Triangle had been formally dismissed yet. It always seemed really fishy but it's not totally impossible that some kind of natural local phenomenon could cause an increase in shipwrecks or plane crashes without resorting to paranormal or extraterrestrial explanations. It's good to know it was all just a fabrication, though.
