coondoggie writes "Next month, with the help of a variety of high-tech gear, researchers will begin a wide-ranging project to better understand the origin, structure and evolution of tornadoes. The National Science Foundation has given $9.1 million to the project called Vortex2 (of course it has a convoluted backronym), which will take place from May 10-June 13. Researchers say Vortex2 is the largest attempt in history to study tornadoes, and will involve more than 50 scientists, 40 research vehicles, and 10 mobile radars, and will cover 900 square miles in southern South Dakota, western Iowa, eastern Colorado, Nebraska, Kansas, the Texas panhandle, and western Oklahoma."

Right now, tornado (and severe thunderstorm) warnings are issued when one of two things happens:
1) A tornado or a funnel cloud is spotted
2) Doppler radar indicates strong rotation and the forecaster believes a tornado is possible or likely
It's always better to detect the tornado vortex signature on radar before a tornado actually develops. There is some lead time, should a tornado actually develop, and people have time to take cover. But the bottom line is that we still warn based on observations, not on a forecast.
A fundamental reason for conducting VORTEX2 is to investigate tornado formation to understand why some supercell thunderstorms are tornadic while others are not. One reason that has been suggested is that warmer rear flank downdrafts are more favorable than colder rear flank downdrafts for tornadogenesis. Physical reasons for this have been proposed, but at this time it still remains untested.
It is hoped that by investigating the storm environment, there will be a better understanding of why some supercell thunderstorms are tornadic while others are not. If the properties of the rear flank downdraft influence the tornado potential, those observations of wind speed, temperature, moisture, and pressure are important. The purpose of understanding why some supercells are tornadic while others are not isn't just for meteorologists to publish papers in journals and get NSF funding. The purpose is to better understand tornado formation in hopes that in the future, tornado warnings are based on forecast tornado potential instead of observing the rotation. If forecasters can predict when tornadic rotation will develop in storms, it will increase the lead time on warnings. It will give people valuable time to alert others of approaching dangerous weather and to take cover.

They do have a vehicle for that. It's called the TIV or Tornado Intercept Vehicle. I live in the Midwest (one of the states mentioned above) and we heard (and saw) that the TIV was passing by last May when a F2 tornado tore through city. If your curious, the vehicle is featured on a show called Storm Chasers on Discovery. http://en.wikipedia.org/wiki/Tornado_Intercept_Vehicle [wikipedia.org]
Yeah, but, can you SHOOT the tornado? I don't think so!
Re: (Score:2, Informative)
As another comment has pointed out, the TIV is exactly such a vehicle. The purpose of the vehicle is to attempt to get good observations of near-surface winds in a tornadic vortex. Mobile radars have done a good job of measuring winds at heights of 75 or 100 meters above the surface. But the question is how strong are the winds near the surface where they actually have the potential to do damage.
In addition to the TIV and the DOW (Doppler On Wheels), pods with instruments are also deployed to take observati

1. Are tornadoes really that dangerous?
Yes that can be very dangerous, capable of rendering concrete building to rubble in seconds. They can rip interstate freeways out of the ground and have been recorded of 1.5 km in size (the small fast moving ones are arguably more dangerous). However they tend to very erratic, they can destroy one house, leave the next door house intact and destroy the one after that. By and large they don't kill huge numbers of people, but they do a lot of damage.
2. Why don't people live away from where tornadoes exist?
Because tornado alley is quite large, much bigger in size than the UK, arguably around Germany in size or larger (depending on how you measure tornado alley). Since your chance of encountering a tornado at your home in any given year is pretty small, people tend to view them about like they do the chances of being struck by lightning. Why abandon the midsection of the country on an oddball chance?
3. Are tornadoes all that dangerous?
Nope, most are small in size and many never even touch down. It's a rare tornado that destroys entire towns.
4. Can they occur at night?
Yup, they definitely can occur at night, (I've encountered one at night and it was pretty freaky).
I'm not a meteorologist or anything, I've just lived through a few and know these questions seem to pop up...

Tornadoes can occur anywhere on the globe. They occur in NY, PA, and New England every year.The ones we get are usually much smaller and do not cause as much damage but have caused significant property damage. My parents' property has been hit a couple of times. One tornado just tore off the tops of a couple of trees, and the other just ripped the foliage off of a swath of trees in the woods, crossed the river next door and caused over a quarter o
