• 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.

As a meteorology major, the dynamics of the atmosphere are of high interest to me. Having a concentration in mesoscale and microscale focuses that interest down.

I went to a lecture granted by Mr Rich Rotunno who presented about "Models of Severe Convection: From Theory to Application" and it was, needless to say, extremely fascinating.

I'm making this thread so, if people of interest wish to share their information on splitting supercells, that would be great! Any links or personally gained knowledge is excellent.

Much appreciated!
 
Here's some factoids I picked up from a COMET module:

Clockwise curving hodographs favor right moving supercells (or right splits)

Counterclockwise curving hodographs favor left moving supercells (or left splits)

Straight lined hodographs favor both left and right splits equally.

I'm not 100% of the reason for these facts, but I think it has an intimate relationship with SRH. If you have a clockwise turning hodograph and a right moving storm, the SRH for that storm will be significantly higher than it would for a left moving storm. The opposite is true for a counterclockwise curving hodograph. For a straight line hodograph, the mean wind vector should like on the midpoint of the hodograph, so that there is some symmetry between left and right moving storms, symmetry such that SRH would be the same for both right and left moving storms (assuming the actual storm motion vectors had the same perturbation from the mean flow), thus favoring both equally.
