My first tornado was June 3rd, 1985. It was a land-spout near Parker, Colorado.

According to the Glossary of Meteorology of the American Meteorological Society "the landspout is an example of the nonsupercell tornado" "with it's vorticity originating in the boundary layer" [= "in contact with the surface of the earth"].
My question: are landspouts the only tornadoes to form from the ground up? I'm asking because of a 2018 small article in Science ( Surprise! Tornadoes form from the ground up)... Thank you very much!

are landspouts the only tornadoes to form from the ground up?

Gustnadoes are the only other that I am aware of.

Gustnadoes are the only other that I am aware of.

And tornadoes...

My first tornado was the Mangum, OK. EF2 on May 20, 2019. I was coming from the north on Highway 283, listening to a live report on FM radio, which gave an exact play by play of the events. Just north of Mangum, I poked out of the rain, and saw a mass of junk under the southwest portion of the supercell, and realized a tornado was hiding in there. I needed only to stop and wait, ready to launch in retreat if necessary. But the tornado rumbled on across the highway and into a field where it dissipated minutes later. Only a handful of chasers or spotters were on site, as most of the others were stuck in a horrific traffic jam to our south. Minutes later, I saw some of the blackest skies I've seen as the storm moved over Granite, OK., while sirens blared.

I was one of the ones stuck in traffic after following it from the South. I did get a horribly contrasted view of that tornado, but it ended up being just another one of many high risk days that left me disappointed
