Appears, at least, that there could be several storms or precipitation areas that could generate outflows strong enough. Furthermore, there is a line of what looks like small vortexes. What you could be looking at is the line where the outflow or gust fronts are colliding (hence 'Gustnado').

Although, Air parcels can still rise rapidly as long as they are hotter then the surrounding air. Did the observer spot multipule storms/ppt areas?

[REDHOT34]

yes i did

Thats a giant landspout.

Thank you for sharing! We also own land in Cochise . Now, we know what to expect. Won't move there for another 5 years.

Thanks,

not true....if u look closely the air is rising rapidly in the vortex....unlike a gustnado where it is not....and the surface temps are high so they are dust devils.

[hailstrm4]

in other terms.... the force of the vortex is concentrated on a small surface area making it more powerful...or it seems so.

Classic landspout...others were dust devils created from the numerous downdrafts seen on vids. No, not all landspouts are laminar. A classic case of a ground circulation latching upward into an updraft...stretching the circulation and creating more vortex speed. Try driving into that vortex at it's peak strength...you'd get flipped in a second.

It is not a Landspout (wich, by the way is something completly different than a gustnado) because landspouts have a characteristic smooth, tubular shape, similar to that of a waterspout and thes whirlwinds dont have that look. also, landspouts have some kind of connection with a cloud namely a funnel reaching out of the ground but strong enough to creat a pretty intense whirlwind on the ground.

Lol sorry thought i wrote too much on the last one. Read up on Snow and Wyatt (1998) on how tornadoes form for that. Yea i have read about links between electrical activity and tornadoes, but many authors say there is too little evidence to support it. See Belcher 1998; Davies, 1993; Davies and Johns, 1993; Dotzek, 2000 and others.

I will say, what i say is based on my understanding of the literature... im no expert :P

[IamArriK]

Your definitions sound correct.  However, we know so little of the dynamic nature of tornadoes and what little we do know is so fluid that many argue that attempts to taxonimise them are a somewhat futile venture.

[mgmirkin]

Landspout: vortex on the ground, only. Funnel cloud: vortex at cloud level, only. Tornado: funnel cloud touches down to ground, or a landspout and funnel connect. Dust Devil / Gustnado: Generally weaker and forms under cloudless or less cloudy conditions. Waterspouts: Like dust devils and tornadoes, but form over water, often dissipating when hitting land.

There may be a significant electrical component to tornadoes as well. Read Peter Thomson, ER Rathbun, Bernard Vonnegut.
