Landspouts are a type of tornado that forms during the growth stage of a cumulus congestus or occasionally a cumulonimbus cloud when an updraft stretches boundary layer vorticity upward into a vertical axis and tightens it into a strong vortex.

2021年9月21日 · If a funnel cloud that touches down over land is called a tornado and a waterspout is a tornado over water, then what is a "landspout"? Landspouts are a type of tornado that forms in a different way. Classic tornadoes form in supercell thunderstorms that contain their own rotating updraft.

2024年9月23日 · Landspouts can look a lot like tornados and can be just as intimidating. In fact, there are some similarities between the two, but how they differ comes down to how they form. A normal tornado can...

2019年6月14日 · There are several types of well-known tornadoes — waterspouts, snowspouts and supercell tornadoes come to mind — but the landspout is unique because it borders the line between a full-blown...

2024年4月9日 · A landspout is similar to a tornado except that it forms when the high and low pressure winds on the ground begin rotating about the same time that a thunderstorm is forming and rises to the storm. You can see what a landspout looks like in this video from northeast Austin captured by a resident.

This article will discuss about Landspout tornadoes, their formation, and what damages they cause to the environment. In 1985, a meteorologist named Howard B. Bluestein coined the name “Landspout.”

2021年4月28日 · While they’re fairly rare around the country, landspouts are very common here. These landspouts may resemble tornadoes but are far weaker and form quite differently. They pack winds well below 100...

Landspout [Slang], a tornado that does not arise from organized storm-scale rotation and therefore is not associated with a wall cloud (visually) or a mesocyclone (on radar). Landspouts typically are observed beneath Cbs or towering cumulus clouds (often as no more than a dust whirl), and essentially are the land-based equivalents of waterspouts.

Landspouts can occur in cumuliform clouds without the parent cloud rotating. Typically, these occur along weather boundary where air converges under weak vertical rotation. The convergence of air at the boundary forces it up forming a cloud and this updraft stretch the rotation increasing its spin.

2021年7月11日 · For a landspout, air near the ground is spinning due to random eddies or colliding boundaries and that spinning air gets sucked up into a developing thunderstorm. Landspout tornadoes are short-lived and normally weak but can still pack winds of up to 100 mph. Landspouts are usually invisible unless they spin dirt or debris from the ground.
