Weather Spotter’s Field Guide - Tornado Life cycle
Scorpion tail shape to roping tornado. Dissipating tornado. With some atmospheric conditions, supercells will go through cycles themselves as the main updraft weakens and is replaced by the next updraft from the flanking line. This can allow for …
Severe Weather 101: Tornado Types - NOAA National Severe …
As few as 20 percent of all supercell thunderstorms actually produce tornadoes. Why does one supercell thunderstorm produce a tornado and another nearby storm does not? What are some of the causes of winds moving at different speeds or directions that create the rotation?
To wedge or not to wedge? Tornado types include many shapes …
Apr 15, 2015 · Landspouts form under different circumstances than your well-known supercell tornado, or their QLCS-type siblings. Landspouts can form on or next to supercells. However, they are a type of tornado that is not associated directly with a mesocyclone.
Wedge, Rope, Cone: What Meteorologists Call Different Types Of Tornadoes
Apr 3, 2024 · Rain-wrapped tornadoes are associated with high-precipitation supercell thunderstorms or can be embedded within squall lines (a line of intense thunderstorms).
Types of Tornadoes – The Michigan Weather Center
Tornadoes come from mainly two types of thunderstorms: supercell and non-supercell. Tornadoes that come from a supercell thunderstorm are the most common, and often the most dangerous. A rotating updraft is a key to the development of a supercell, and eventually a tornado.
There are different types of tornadoes: wedges, elephant trunks ... - CNN
Nov 28, 2022 · Wedges are generally the biggest and most destructive twisters. They’re pretty easy to spot because they’re usually as wide as they are tall. Wedges come from supercell thunderstorm systems,...

Tornadoes that come from a supercell thunderstorm are the most common, and often the most dangerous. A rotating updraft is key to the development of a supercell, and eventually a tornado.
Spotter's Field Guide - The Supercell, Pt. 1 - National Weather Service
Supercells can produce extremely large hail and strong, violent, tornadoes and produce damaging outflow winds in excess of 100 mph. As a spotter, it is essential to become familiar with the visual aspects underneath these intense thunderstorms.
In intense supercells, mid-level mesocyclone becomes strong enough to wrap precipitation around to backside of updraft, creating a characteristic pendant or hook echo. Low-level mesocyclone (from which a tornado can form) is located within notch of hook.
