The term "multivortex," which is short for "multiple vortex" is used to describe a tornado with two or more subvorticies or suction vorticies moving around inside it. These vorticies have stronger winds than those found in other parts of the tornado and often produce crescent-shaped areas of more severe damage.
Sometimes these vorticies are visible, giving the appearance of two or more tornadoes when it is still in fact one larger tornado.
The closest thing to an antonym for multivortex is single vortex.
There are multivortex tornadoes that at times can look like they are made up of two or more tornadoes
That is impossible to determine. First, tornadoes, multivortex included, have been around longer than there have been people to record them . Also, existence of multiple vortex tornadoes was not confirmed until the early 1970s. In earlier accounts it is difficult to determine whether they are describing one multivortex tornado, or multiple separate tornadoes.
No, There is no type of tornado that starts with X. Tornadoes can be divided into supercell tornadoes, landspouts, and waterspouts. Some supercell tornadoes are also multivortex.
Yes. When a single storm system produces multiple tornadoes in a relatively short time over an area it is called a tornado outbreak. There are usually several small outbreaks and one or two large outbreaks each year. Additionally, often within an outbreak, one thunderstorm can produce several tornadoes in succession. This is called a tornado family. Another phenomenon often mistaken for groups of tornadoes is a multivortex tornado. A multivortex tornado contains smaller, short lived vortices within the main circulation. In some cases this may look like several tornadoes moving in circles, but it is really one tornado.
Usually they do, but there are multivortex tornadoes. These have small vortices, almost like smaller tornadoes, circling inside the main circulation. Most of the time these vorticies are hidden inside the main funnel, but sometimes, if the humidity is right these smaller vorticies are visible as multiple funnels
A "double tornado" is scientifically known as a multiple vortex or multivortex tornado. In such tornadoes smaller vortices form within the main vortex of the tornado. These subvortices usually do not last long and individually do not impact the overall tornado very much. Rather than indicating a lack of organization in the tornado, a multivortex structure usually indicates a strong tornado.
It depends on the tornado. If it is a single vortex tornado the winds near at the edge of the core will be the fastest. However, many of the strongest tornadoes are multivortex, meaning that they have smaller vorticies (almost like mini tornadoes) inside the main vortex. In a multivortex tornado the fastest winds are within these subvortices.
It depends on the tornado. In most tornadoes the strongest winds are near the center. In multivortex tornadoes, however, the strongest winds are in the subvorticies, which are almost like smaller tornadoes within a larger one.
At least 40. Some of the better known: "The Wizard of Oz" (1939) "Places in the Heart" (1984) "Twister" (1996) "Where the Heart Is" (2000) "The Day After Tomorrow" (2004)
Scientists understand that tornadoes are a type of small but violent windstorm with both intense rotating winds and very strong updrafts. Tornadoes form from strong thunderstorms, but scientists only partially understand the exact mechanisms of their formation. (see below links for more information). Scientists know that tornadoes vary in strength, size, forward speed and duration. Although stronger tornadoes tend to be larger and longer lasting, this is not always the case. These tornadoes can cause anything from minor damage to total destruction. Tornadoes usually follow a straight path, but can make turns while others have followed meandering paths. Tornadoes often occur in outbreaks, where multiple tornadoes form from one storm system within a day or two. The strongest of tornadoes often occur in such outbreaks. Some tornadoes break down to produce multiple suction vortices, which produce narrow, curved swaths of damage that is more severe than that from the rest of the tornado. The are call multiple vortex or multivortex tornadoes. Many of the strongest tornadoes are multivortex.
A multivortex or multiple vortex tornado is a tornado that has multiple suction vortices or subvorticies inside the main circulation. These short-lived vorticies are more intense than the rest of the tornado, sometimes packing wind up to 100 mph faster than the main circulation. Although the subvorticies are often obscured by the main funnel they sometimes show themselves as multiple funnels moving around a common center. It is still one tornado, however, even though it may look like two or more.
