• 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.

New paper about electric signals generated by tornadoes

This one just dropped in:

Leeman, J.R. and Schmitter, E.D. 2009: Electric signals generated by tornadoes.- Atmospheric Research 92: 277-279.

Abstract: Severe weather events generate electrical phenomena beyond those related to lightning discharges. In the present letter we suggest that as precipitation like rain, hail stones, and dirt move in the thunderstorm they generate an electrical signature that is characteristic for the rotation properties of the associated storm. A case study is offered which clearly demonstrates that this electrical signature is present and detectable, though it is quite weak. It can be observed that as the speed of rotation increases and diameter decreases the emitted frequency increases as would be anticipated. Comparison to synchronous radar, surface and visual data suggest that developing tornadoes in this way can be detected earlier than currently feasible weather surveillance radars.
 
Isn"t it also true that tornadoes send out a weak signal very close to the old channel 2 on analog tv. It may be a myth .
