• After witnessing the continued decrease of involvement in the SpotterNetwork staff in serving SN members with troubleshooting issues recently, I have unilaterally decided to terminate the relationship between SpotterNetwork's support and Stormtrack. I have witnessed multiple users unable to receive support weeks after initiating help threads on the forum. I find this lack of response from SpotterNetwork officials disappointing and a failure to hold up their end of the agreement that was made years ago, before I took over management of this site. In my opinion, having Stormtrack users sit and wait for so long to receive help on SpotterNetwork issues on the Stormtrack forums reflects poorly not only on SpotterNetwork, but on Stormtrack and (by association) me as well. Since the issue has not been satisfactorily addressed, I no longer wish for the Stormtrack forum to be associated with SpotterNetwork.

    I apologize to those who continue to have issues with the service and continue to see their issues left unaddressed. Please understand that the connection between ST and SN was put in place long before I had any say over it. But now that I am the "captain of this ship," it is within my right (nay, duty) to make adjustments as I see necessary. Ending this relationship is such an adjustment.

    For those who continue to need help, I recommend navigating a web browswer to SpotterNetwork's About page, and seeking the individuals listed on that page for all further inquiries about SpotterNetwork.

    From this moment forward, the SpotterNetwork sub-forum has been hidden/deleted and there will be no assurance that any SpotterNetwork issues brought up in any of Stormtrack's other sub-forums will be addressed. Do not rely on Stormtrack for help with SpotterNetwork issues.

    Sincerely, Jeff D.

I can't believe I didn't see this before (it's about six months old as of this posting)

The Mesoscale and Microscale Meteorology (MMM) lab at NCAR has released the recording of a 1-hour seminar given by Paul Markowski at Penn State (one of the leading researchers on tornadoes, both observationally and through modeling). It's a lot to chew on, and if you are not familiar with basic kinematics and prior knowledge/understanding on the subject, you'll probably struggle a bit to follow along. I can help explain things as they come up.


If you want to skip to the takeaway messages (may not mean much without the context from the rest of the presentation), use this link: takeaway messages

Perhaps the most condensed summary messages I can include here from my take from watching:
-There are probably multiple mechanisms that result in tornadoes in storms that otherwise look nearly identical
-It's not all about what happens behind the RFD gust front boundary - naked near-surface inflow turbulence can have a major impact
-We still don't know for sure - modeling studies are becoming increasingly realistic, but still neglect some likely impactful factors (one cited example: anvil cloud shading was not factored in)
-Ultimately, random/stochastic turbulence likely plays a substantial role in getting a tornado in a supercell. What a supercell does more than anything is provide a nurturing environment for tornadoes to form rather than directly force them to occur.
