Tornado - Wikipedia. A tornado is a rapidly rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. They are often referred to as twisters, whirlwinds or cyclones,[1] although the word cyclone is used in meteorology to name a weather system with a low- pressure area in the center around which winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern.[2] Tornadoes come in many shapes and sizes, and they are often visible in the form of a condensation funnel originating from the base of a cumulonimbus cloud, with a cloud of rotating debris and dust beneath it. Most tornadoes have wind speeds less than 1. The most extreme tornadoes can attain wind speeds of more than 3. Transylmania Full Movie Part 1 on this page. Various types of tornadoes include the multiple vortex tornado, landspout and waterspout.

Waterspouts are characterized by a spiraling funnel- shaped wind current, connecting to a large cumulus or cumulonimbus cloud. They are generally classified as non- supercellular tornadoes that develop over bodies of water, but there is disagreement over whether to classify them as true tornadoes. These spiraling columns of air frequently develop in tropical areas close to the equator, and are less common at high latitudes.[6] Other tornado- like phenomena that exist in nature include the gustnado, dust devil, fire whirls, and steam devil. Tornadoes have been observed and documented on every continent except Antarctica. However, the vast majority of tornadoes occur in the Tornado Alley region of the United States, although they can occur nearly anywhere in North America.[7] They also occasionally occur in south- central and eastern Asia, northern and east- central South America, Southern Africa, northwestern and southeast Europe, western and southeastern Australia, and New Zealand.[8] Tornadoes can be detected before or as they occur through the use of Pulse- Doppler radar by recognizing patterns in velocity and reflectivity data, such as hook echoes or debris balls, as well as through the efforts of storm spotters. There are several scales for rating the strength of tornadoes. The Fujita scale rates tornadoes by damage caused and has been replaced in some countries by the updated Enhanced Fujita Scale.

A tornado is "a violently rotating column of air, in contact with the ground, either pendant from a cumuliform cloud or underneath a cumuliform cloud, and often (but.

An F0 or EF0 tornado, the weakest category, damages trees, but not substantial structures. An F5 or EF5 tornado, the strongest category, rips buildings off their foundations and can deform large skyscrapers. The similar TORRO scale ranges from a T0 for extremely weak tornadoes to T1. Doppler radar data, photogrammetry, and ground swirl patterns (cycloidal marks) may also be analyzed to determine intensity and assign a rating.[1. A tornado near Anadarko, Oklahoma.

The funnel is the thin tube reaching from the cloud to the ground. The lower part of this tornado is surrounded by a translucent dust cloud, kicked up by the tornado's strong winds at the surface. The wind of the tornado has a much wider radius than the funnel itself.

A tornado near Eads, Colorado. Etymology. The word tornado is an altered form of the Spanish word tronada, which means "thunderstorm". This in turn was taken from the Latin tonare, meaning "to thunder".

It most likely reached its present form through a combination of the Spanish tronada and tornar ("to turn"); however, this may be a folk etymology.[1. A tornado is also commonly referred to as a "twister", and is also sometimes referred to by the old- fashioned colloquial term cyclone.[1. The term "cyclone" is used as a synonym for "tornado" in the often- aired 1.

The Wizard of Oz. The term "twister" is also used in that film, along with being the title of the 1.

Twister. Definitions. A tornado is "a violently rotating column of air, in contact with the ground, either pendant from a cumuliform cloud or underneath a cumuliform cloud, and often (but not always) visible as a funnel cloud".[1. For a vortex to be classified as a tornado, it must be in contact with both the ground and the cloud base. Scientists have not yet created a complete definition of the word; for example, there is disagreement as to whether separate touchdowns of the same funnel constitute separate tornadoes.[5]Tornado refers to the vortex of wind, not the condensation cloud.[1. Funnel cloud. This tornado has no funnel cloud; however, the rotating dust cloud indicates that strong winds are occurring at the surface, and thus it is a true tornado. A tornado is not necessarily visible; however, the intense low pressure caused by the high wind speeds (as described by Bernoulli's principle) and rapid rotation (due to cyclostrophic balance) usually cause water vapor in the air to condense into cloud droplets due to adiabatic cooling.

This results in the formation of a visible funnel cloud or condensation funnel.[1. There is some disagreement over the definition of a funnel cloud and a condensation funnel. According to the Glossary of Meteorology, a funnel cloud is any rotating cloud pendant from a cumulus or cumulonimbus, and thus most tornadoes are included under this definition.[2. Among many meteorologists, the 'funnel cloud' term is strictly defined as a rotating cloud which is not associated with strong winds at the surface, and condensation funnel is a broad term for any rotating cloud below a cumuliform cloud.[5]Tornadoes often begin as funnel clouds with no associated strong winds at the surface, and not all funnel clouds evolve into tornadoes.

Most tornadoes produce strong winds at the surface while the visible funnel is still above the ground, so it is difficult to discern the difference between a funnel cloud and a tornado from a distance.[5]Outbreaks and families. Occasionally, a single storm will produce more than one tornado, either simultaneously or in succession.

Multiple tornadoes produced by the same storm cell are referred to as a "tornado family".[2. Several tornadoes are sometimes spawned from the same large- scale storm system.

If there is no break in activity, this is considered a tornado outbreak (although the term "tornado outbreak" has various definitions). A period of several successive days with tornado outbreaks in the same general area (spawned by multiple weather systems) is a tornado outbreak sequence, occasionally called an extended tornado outbreak.[1. Characteristics. Size and shape. Most tornadoes take on the appearance of a narrow funnel, a few hundred yards (meters) across, with a small cloud of debris near the ground. Tornadoes may be obscured completely by rain or dust. These tornadoes are especially dangerous, as even experienced meteorologists might not see them.[2.

Tornadoes can appear in many shapes and sizes. Small, relatively weak landspouts may be visible only as a small swirl of dust on the ground. Although the condensation funnel may not extend all the way to the ground, if associated surface winds are greater than 4. A tornado with a nearly cylindrical profile and relative low height is sometimes referred to as a "stovepipe" tornado. Large single- vortex tornadoes can look like large wedges stuck into the ground, and so are known as "wedge tornadoes" or "wedges".

The "stovepipe" classification is also used for this type of tornado if it otherwise fits that profile. A wedge can be so wide that it appears to be a block of dark clouds, wider than the distance from the cloud base to the ground. Even experienced storm observers may not be able to tell the difference between a low- hanging cloud and a wedge tornado from a distance.

Many, but not all major tornadoes are wedges.[2. Tornadoes in the dissipating stage can resemble narrow tubes or ropes, and often curl or twist into complex shapes. These tornadoes are said to be "roping out", or becoming a "rope tornado". When they rope out, the length of their funnel increases, which forces the winds within the funnel to weaken due to conservation of angular momentum.[2.

Yes, Google Uses Its Power to Quash Ideas It Doesn’t Like—I Know Because It Happened to Me [Updated]The story in the New York Times this week was unsettling: The New America Foundation, a major think tank, was getting rid of one of its teams of scholars, the Open Markets group. New America had warned its leader Barry Lynn that he was “imperiling the institution,” the Times reported, after he and his group had repeatedly criticized Google, a major funder of the think tank, for its market dominance. The criticism of Google had culminated in Lynn posting a statement to the think tank’s website “applauding” the European Commission’s decision to slap the company with a record- breaking $2.

That post was briefly taken down, then republished. Soon afterward, Anne- Marie Slaughter, the head of New America, told Lynn that his group had to leave the foundation for failing to abide by “institutional norms of transparency and collegiality.”Google denied any role in Lynn’s firing, and Slaughter tweeted that the “facts are largely right, but quotes are taken way out of context and interpretation is wrong.” Despite the conflicting story lines, the underlying premise felt familiar to me: Six years ago, I was pressured to unpublish a critical piece about Google’s monopolistic practices after the company got upset about it. In my case, the post stayed unpublished. I was working for Forbes at the time, and was new to my job. In addition to writing and reporting, I helped run social media there, so I got pulled into a meeting with Google salespeople about Google’s then- new social network, Plus. The Google salespeople were encouraging Forbes to add Plus’s “+1" social buttons to articles on the site, alongside the Facebook Like button and the Reddit share button. They said it was important to do because the Plus recommendations would be a factor in search results—a crucial source of traffic to publishers.

This sounded like a news story to me. Google’s dominance in search and news give it tremendous power over publishers.

By tying search results to the use of Plus, Google was using that muscle to force people to promote its social network. I asked the Google people if I understood correctly: If a publisher didn’t put a +1 button on the page, its search results would suffer? The answer was yes. After the meeting, I approached Google’s public relations team as a reporter, told them I’d been in the meeting, and asked if I understood correctly.

The press office confirmed it, though they preferred to say the Plus button “influences the ranking.” They didn’t deny what their sales people told me: If you don’t feature the +1 button, your stories will be harder to find with Google. With that, I published a story headlined, “Stick Google Plus Buttons On Your Pages, Or Your Search Traffic Suffers,” that included bits of conversation from the meeting. The Google guys explained how the new recommendation system will be a factor in search.

Universally, or just among Google Plus friends?” I asked. Universal’ was the answer. So if Forbes doesn’t put +1 buttons on its pages, it will suffer in search rankings?” I asked. Watch Big Mamma`S Boy Online Big Mamma`S Boy Full Movie Online. Google guy says he wouldn’t phrase it that way, but basically yes.(An internet marketing group scraped the story after it was published and a version can still be found here.)Google promptly flipped out. This was in 2. 01. Google never challenged the accuracy of the reporting.

Instead, a Google spokesperson told me that I needed to unpublish the story because the meeting had been confidential, and the information discussed there had been subject to a non- disclosure agreement between Google and Forbes. I had signed no such agreement, hadn’t been told the meeting was confidential, and had identified myself as a journalist.) It escalated quickly from there. I was told by my higher- ups at Forbes that Google representatives called them saying that the article was problematic and had to come down. The implication was that it might have consequences for Forbes, a troubling possibility given how much traffic came through Google searches and Google News. I thought it was an important story, but I didn’t want to cause problems for my employer. And if the other participants in the meeting had in fact been covered by an NDA, I could understand why Google would object to the story. Given that I’d gone to the Google PR team before publishing, and it was already out in the world, I felt it made more sense to keep the story up.

Ultimately, though, after continued pressure from my bosses, I took the piece down—a decision I will always regret. Forbes declined comment about this. But the most disturbing part of the experience was what came next: Somehow, very quickly, search results stopped showing the original story at all. As I recall it—and although it has been six years, this episode was seared into my memory—a cached version remained shortly after the post was unpublished, but it was soon scrubbed from Google search results.

That was unusual; websites captured by Google’s crawler did not tend to vanish that quickly. And unpublished stories still tend to show up in search results as a headline. Scraped versions could still be found, but the traces of my original story vanished. It’s possible that Forbes, and not Google, was responsible for scrubbing the cache, but I frankly doubt that anyone at Forbes had the technical know- how to do it, as other articles deleted from the site tend to remain available through Google.

Deliberately manipulating search results to eliminate references to a story that Google doesn’t like would be an extraordinary, almost dystopian abuse of the company’s power over information on the internet. I don’t have any hard evidence to prove that that’s what Google did in this instance, but it’s part of why this episode has haunted me for years: The story Google didn’t want people to read swiftly became impossible to find through Google. Google wouldn’t address whether it deliberately deep- sixed search results related to the story. Asked to comment, a Google spokesperson sent a statement saying that Forbes removed the story because it was “not reported responsibly,” an apparent reference to the claim that the meeting was covered by a non- disclosure agreement. Again, I identified myself as a journalist and signed no such agreement before attending. People who paid close attention to the search industry noticed the piece’s disappearance and wroteaboutit, wondering why it disappeared. Those pieces, at least, are still findable today.

As for how effective the strategy was, Google’s dominance in other industries didn’t really pan out for Plus. Six years later, the social network is a ghost town and Google has basically given up on it. But back when Google still thought it could compete with Facebook on social, it was willing to play hardball to promote the network. Google started out as a company dedicated to ensuring the best access to information possible, but as it’s grown into one of the largest and most profitable companies in the world, its priorities have changed. Even as it fights against ordinary people who want their personal histories removed from the web, the company has an incentive to suppress information about itself. Girl, Interrupted Full Movie Online Free. Google said it never urged New America to fire Lynn and his team. But an entity as powerful as Google doesn’t have to issue ultimatums.

It can just nudge organizations and get them to act as it wants, given the influence it wields. Lynn and the rest of the team that left New America Foundation plan to establish a new nonprofit to continue their work.

For now, they’ve launched a website called “Citizens Against Monopoly” that tells their story. It says that “Google’s attempts to shut down think tanks, journalists, and public interest advocates researching and writing about the dangers of concentrated private power must end.”It’s safe to say they won’t be receiving funding from Google.
