WHAT IS A MESOCYCLONE?
The engine of the strongest and most dangerous thunderstorms and the bringer of the most intense tornadoes on Earth is the mesocyclone. When a thunderstorm develops in an atmosphere with strong changes of wind speed and/or direction with height, the updraft may twist and rotate as a vertical column becoming a mesocyclone. The effects of this mesocyclone on storm clouds can appear otherworldly with wind sculpted structures resembling flying saucers, alien crafts hovering below the storm base or invading motherships casting ominous shadows.
The presence of a mesocyclone can enable a thunderstorm to persist for hours as a supercell. Technically, "mesocyclone" is a term used for radar analysis defining storm-scale rotation in convective storms that meets specific magnitude, vertical depth and duration.
- Cyclonically rotating vortex in a convective storm
- 2-10 km in diameter
- Vorticity 10-2 S-1 or greater
When Doppler radar detects a mesocyclone exhibiting intensifying rotation, a tornado warning may be issued. Most mesocyclones don’t produce tornadoes. Sometimes they produce small brief tornadoes. Sometimes they summon enormous, long-lived monsters. Mesocyclones are often accompanied by frequent lightning activity that is especially evident at night. On May 25th, this year in New Mexico storm chasers gawked for hours as an almost stationary supercell delivered an out-of-this-world light show.

Still the best storm chaser on YouTube. No overhyped build-up, no loud obnoxious behavior. You've still got it Hank!
-
Pecos Hank is not just a storm chaser, he's an artist.
-
-
Not only is this man lectures us about weather events, he also makes music now. That's talent and dedication on another level.
-
Idk why, but I’d pay for an 1 hour video of just a complication of mesocyclones with thunder and quiet music playing in the background
-
Pecos Hank is the Bob Ross of storm chasing.... an artist with a love of animals.
-
Pecos Hank: Tornado warning. YouTube captions: Burrito warning. ...What? They both bring deadly wind, don't they?
-
All this amazing footage that took so long to gather, edited down to a four minute video. So grateful for your love of nature and your love of sharing what you find… I don’t think there’s a higher quality YouTube channel out there. Your love for weather and tornadoes shines through these videos, and I’m glad to watch each and every one of them. Thanks, Hank

I forgot how relaxing his content is

I think a lot of people forget to show appreciation and praise to Hank for making his own background music. It really sets the mood, intense, calm, ethereal. He makes all this beautiful music that just flies by our minds while we watch the stunning footage he captures. I bet you never once question the music in the background and go "this music doesn't really fit in". You either notice the music because you want to, or it fits in so well its just brushes past your conscious. Very talented, very creative, and all around quality.. you just create amazing content in many forms Hank. 👍👍👍👍👍

No one: The subtitles: Sometimes they produce small brief burritos.

I was chasing on May 25th with the IL College Of DuPage Storm Chasers that night. It was one of the most intense thunderstorms i have even seen in my entire life as a kid growing up in IL and nothing was comparable to that night. We were near Grady New Mexico in the mountains or hills towards the south while there was rotation towards the north downhill with the most intense lightning I’ve seen in many many years. We sat out there 40 minutes to enjoy the light show while predicting if the rotation downhill would spawn a tornado. Within those 40 minutes nothing happened so we assumed that was the end of it so we headed back until 5 minutes later after driving downhill we spotted a big wedge tornado that was probably on the ground for a good couple minutes but it was very hard to see it. It was therefore my first tornado that I have ever seen in New Mexico. It was such a Beaty with 50mph - 70mph winds by us while it sounded like a freight train while the tornado was about 4-7 miles from us. We tried to call it in, but nobody answered (WHICH IS A PROBLEM) but luckily it was in the middle of nowhere and only lasted for several minutes that night. My estimate of the tornado was probably anywhere between an EF1 to an EF2 at most but it was really big and it almost looked like an EF3 instead but again it was in the middle of nowhere. I’ll never forget that night and that trip I was on with college of DuPage. MOTHER NATURE is such a Beauty and this is why I want to become an Extreme Professional Storm Chaser like many others because it’s been my passion since I was 6. Great video

pecos hanks uploading is like christmas it doesn’t come often but everyone loves when it does well done hank, your content is amazing
-
Holy cow. These storms are incredibly beautiful and terrifying. You are lucky to encounter so many over the years, Hank - I wish you the best and I hope you keep encountering more. Just… just don’t die in one of them, though. That would be bad. Really bad.

The narrator would be a very good voice actor for a horror movie---the ability to hold the long pauses, the quiet drama in his voice, and being able to describe things that would normally never be thought twice about, but he makes it seem ominous. Quite the ability 😄
-
I’m from Vietnam and adults here are sometimes uncomfortable when seeing a lightning because our parents often tell us when we’re young that if we ever talk back the lightning god will strike us ( i know it’s horrible way to discipline a kid ). Anyway, I’m no different than those adults. However I found beauty in them since I found your channel. Thank you for that ❤️❤️❤️.

Nice soundtrack, too!
-
This video definitely need a seizure warning. I already had one from how beautiful it is.
-
This is one of the reasons I've always loved Pecos Hank's videos. Instead of just looking at a tornado, he often captures the whole swirling architecture of the supercell. We are able to see so much more - the tails of clouds steaming into the supercell, the sky turning icy green, and the myriad ghostly vortices that dance all around the outside of the tornado. I had no idea that such things even existed. Amazing music, again.

Beautiful stuff as always.
