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
Tornadoes are generally funnel or cone shaped.
A funnel cloud is associated with severe thunderstorms or tornadoes. It forms when rotating air creates a condensation funnel that extends from the base of the cloud towards the ground. Funnel clouds can develop into tornadoes if the right conditions are present.
Only if they touch the ground or produce damaging wind at ground llevel.
A funnel with the narrow end of the funnel pointed downward.
Yes, some strong tornadoes create brief satellite tornadoes that circle the main funnel.
They are often visible as funnel clouds, but these clouds are not necessarily very large.
No, hurricanes do not have funnel-shaped clouds. They have a wide expanse of swirling clouds that form a dense, circular shape around the storm's center called the eye. Funnel clouds are typically associated with tornadoes, not hurricanes.
A synonym for funnel cloud is condensation funnel. Tornado may also be considered a synonym, though this is a bit loose as not all funnel clouds become tornadoes, and some tornadoes do not have a visible funnel.
It is not uncommon for larger tornadoes to last longer, but not always. For example, the first of two tornadoes near Happy, Texas on May 5, 2002 had an extremely larger funnel, but lasted only about 15 minutes, while other, smaller tornadoes have lasted for over an hour.
Not necessarily. While a funnel cloud often does indicate a tornadic circulation, it is not considered a tornado unless the circulation reaches the ground. There is also a poorly understood phenomenon called a cold air funnel, which is not related to tornadoes
A funnel cloud is a rotating cloud that extends downward from a thunderstorm, while a tornado is a funnel cloud that has touched the ground. In other words, all tornadoes start as funnel clouds, but not all funnel clouds develop into tornadoes.
Tornadoes are associated with funnel clouds.
