Amazing video! I've been trying to research how landspouts form for a few months now and while I found some answers online, your video answered a multitude of my questions. Thank you!
During the off season you should do a series covering all the spc meso analysis products. I know a bunch of them, but I'd love a complete understanding.
For your section on how the landspouts themselves form, this kind of gives me some better understanding of the landspouts I had spotted in Texas back in september formed. That day had some convective mode, and I was pouring over the data, and figured if I set up close to the caprock, then I would be in a good position for seeing some storms fire off. My thinking was the terrain change would provide a favorable environment for initiation. I was 100% spot on and I had a grand time just driving around taking some pictures, and enjoying a good show of storms. Well, during all that, I watched a landspout form not too far from the edge of the caprock, and it lingered for a good 10 minutes. Given this terrain change provides a good environment for eddies like the paper notes, this explains why it formed where it did. In a way, this video helps add context and enjoyment to the sights I saw on the 15th. Thanks for the video!
Thank you very much for the detailed forecasting on these events. I live in southern Arizona and have been on the hunt for these elusive events. This was a very clear and clean insight and I very much appreciate the time you took to make this. Especially loved the Mogollan Rim explanation and seeing Jeremy's image :)
This is the most Professional, most needed- due to trivializatio- expose' ever made! I hail from Cienfuegos Bay in South Central Cuba which has been called by many "The Global Capital of Sea Tornadoes" !!!!! My Grandparents and my Parents had residences and businesses all along the very large, amphiteatre-shaped Bay. This area, including the moderate "hill ranges" to the east, is known-notorious- for being where all the very "superwarm" water of the Caribbean Sea piles up formidably.We would make at least two 45-minute boat or ferry voyages in this "amphiteatre" daily. Except on cold Winter days, it would become a "navigation through a mine field" with often quite small incipient vortices reflected on the water surface as puny dark circles !! Now-- ALL-- spout phenomena-- CAN-- be lethal ! Fishermen would quip: "Sea Tornados don't kill people---- SHARKS DO !!!! Congratulations on being a disciplined, thorough Scientist !!!!
Great video very informative ive never been able to see 1 yet technically, i live right by Lake Erie so i see there counterparts the Fairweather Weather Waterspouts alot in the fall (I've observed a Fairweather waterspout come ashore and stay for a couple minutes weather thats considered a brief Landspout Tornado or Tornado is always a hot debate) ive aslo seen a Couple Tornadic Waterspouts on Lake Erie to (i think 2-3 not many at all) October 7th 2023 i observed 55 Waterspout Funnel Clouds and 7 Mature Waterspouts
Very informative video, I had not seen this before / you had mentioned that a land spout is considered a tornado. Would that also be true for a water spout or a gustnado / I found an interesting article about the Carr fire in northern California years ago that actually produced an EF three fire tornado and the article said that the fire created supercell like conditions? I also saw where a tornado warning was issued out of the Reno Nevada office for a fire that actually did produce a tornado over eastern California or Western Nevada/as Mr. Spock says “ fascinating”
Thank you! Waterspouts are considered tornadoes, but gustnadoes are not. That Carr Fire tornado was pretty crazy; the fire changed the environment enough so that a legitimate supercellular tornado occurred.
From learning about landspouts in this video it seems pretty similar to waterspouts with how the circulation occurs but the parameters are slightly different. The boundaries colliding and the slow progression is similar to how waterspouts would occur but the lapse rates arent as strong specifically mid level lapse rates. The low level lapse rates are similar due to the intense heating and moisture but those sea breeze boundaries are great for thunderstorm development but can they cause rotation and vorticity for those storms to ride it and produce. Anyways great video as always
@@ConvectiveChronicles I’ve always wanted to witness a waterspout but I rarely get to go to the gulf states because I don’t really have anyone that lives in the gulf coast except one family member during the summer
Thanks a lot for this! I love your tutorials and this is really useful. I forecast for the Chicago area and we have landspouts here more than people may think. This is primarily because on hot, humid, and unstable days during summer, a cooler air mass sometimes emerges from the cooler waters of lake Michigan (the "lake breeze"), creating a convergence zone/boundary. these boundaries usually slow down and stall as they move inland through the Chicago metro, and if storms can interact with them they can lead to landspouts (we had an event with three landspouts on May 7 this year, and another landspout event on May 31). I do have two questions: First, can these techniques be used to forecast fair-weather waterspouts as well? And second, what's your opinion on NWS offices issuing tornado warnings for landspouts? My local office usually just issues special weather statements with a "landspout possible" tag on them, but I have seen other offices issue tornado warnings for short-lived landspouts. (often times by the time they've issued a warning the landspout has dissipated and now they've issued a false alarm). Just curious to know your thoughts on that, since I wonder if it's really worth warning for these (except cases where chasers confirm a strong landspout) when it could cause the pubic to take tornado warnings less seriously.
Thank you! Sea-breeze/lake-breeze boundaries are great examples of boundaries that can produce landspouts! Yes, the formation mechanisms for fair-weather waterspouts are very similar to that of landspouts. As for tornado warnings for landspouts, it's a tough call given their drive to lower the false alarm rate. I think if you have legit evidence of a robust landspout, a tornado warning is warranted. If it's one of those little brief spin-ups in an open field, perhaps a special weather statement with a tor possible tag is enough. Just tough to say, as it's a situation by situation basis.
Silly question why do some Fairweather Waterspouts take that more classic Tornado look with there Funnels? I noticed that Landspouts don't usually do that as much
I’m not 100% sure. Fair-weather waterspouts form in a very similar fashion to landspouts. A very large percentage of landspouts do have a funnel associated with them; a landspout has to have that connection to the cloud base to be called a landspout, and that connection often does manifest itself in a funnel. Same thing with a fair-weather waterspout.
@ConvectiveChronicles so many times I see Fairweather waterspout with only Part or Half a Funnel visible above a spray ring or clear disturbance on the water under it. its always a hot debate when reporting those because some will say it's just a funnel cloud or others will say it's a waterspout or it has to be fully condensed to the water to be a waterspout what's your take? I'm sure that happens with Landspouts as well. To me if it has a Spray ring/disturbance on the water regardless what the funnel size is it's a waterspout to me
No, they are not the same. Spin-ups on the leading edge of an MCS are caused by little eddies on the leading edge and do not form via vorticity stretching by updrafts into the vertical like landspouts are.
Finally back tracking through a couple of these video. Landspouts I still laugh when people don't call them tornadoes or they aren't as interesting as a more "legit" tornado. I tell these people to either to robustly "***k off" or please tell me how your standards are that out of wack where even seeing a landspout isn't enjoyable. I swear people need to come live in the Northeast and Upstate NY here for an extended time and see how often we get tornadoes in general....I'd dream of seeing a landspout at least. I know at least what seem to be all the Northeast chasers have seen at least one tornado up here in the Northeast somewhere and have it on video but living here my entire life and filming or so around Albany's 1 hour chase radius or so I have....I never seen a tornado up here in general. Kind of crazy. Now the last landspout or in general tornado I have seen was in June 2021, a 5 minute one in Western Nebraska and we were the only chasers in the U.S. that saw it that day and was the only tornado we have seen in the chase trips we have done since 2018. Only tornado seen since 2010. We did see a good number of them or tiny tornadoes in 2010 during that 2 weeks chase trip in college but yeah landspouts are always a joy to see even if they are quite uncommon for me and almost downright rare as hell here in the Northeast. I did find the parameters for landspouts in this to be interesting as a few seemed obvious but I had no clue about the Non-tornado parameter in terms of for landspouts as I basically never use that nor the Stretching parameter. That 2nd one was very interesting as I didn't even know that one was a thing.
Watching the video now and if you bring this up later as I watch I will delete this comment. I just needed to put it out there because I don’t wanna forget. I’ve heard about things like “hybrid” tornadoes, I guess part landspout, part supercellular? I’ve seen people refer to some tornadoes as this, I believe the 2016 Wray Colorado tornado is often referred to as one of these “hybrids”. Not sure how these work, maybe another video topic if it’s not mentioned here.
Hybrid tornadoes have characteristics of both landspout and supercellular tornadoes. Typically they will develop as a normal landspout does and then become entrenched in the mesocyclone of the supercell.
This was fantastic, Trey! We definitely get our fair share of waterspouts here on the Gulf Coast of Florida. Very interesting the similarities of this to our waterspouts as you pointed out. Had a pretty nasty one about 8 miles from my home approximately 3 weeks ago (ua-cam.com/users/shortsWiWA_KL7T3k?feature=share). Thank you again for this material!
Finally! A video on landspouts. It’s been hard finding videos on landspouts. Thank you trey
You bet!
i’ve been on the hunt for a video like this, killer!

Very nice! The Caprock (the TX Panhandle in general) is a very reliable hotspot for landspouts.

Am I missing the link to the DZVZ pics?
Not sure which pics you’re referring to, but the Szoke et al (2006) article is linked in the description.
Awesome tutorial!
Thanks, Will!
Are these the same as spin up tornados on derechos/storm boundaries. Or not because theyre too fast mocing?
No, they are not the same. Spin-ups on the leading edge of an MCS are caused by little eddies on the leading edge and do not form via vorticity stretching by updrafts into the vertical like landspouts are.
Do they pose any danger?
They do; landspouts have produced EF2-3 damage before
