• 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.

Hello all,

I´m a Dutch weather enthusiast and I´ve made a detailed radar animation of the so called ´super derecho´ with very strong bookend vortex of 8 may 2009, which is an interesting event for me.

All data used by me were downloaded from the NOAA NEXRAD radar archive and displayed with GR2Analyst. The images in the animation show both reflectivity and velocity data.
The video consists of 2 parts, where part 1 shows a compilation of data from all radar sites in the vicinity of the derecho. For each part of that animation I chose the radar site which gave the best combination of reflectivity and velocity data.
Part 2 is divided in time frames of mostly 2 hours and shows for each time frame data from all radar sites in the vicinity of the bookend vortex. I did that to give a completer picture of the phenomen.

I placed it here because I thought it might be interesting for some of you.

The video:

Of course Youtube compresses the video a little, so if there is someone who wants to see part 1 in higher quality, he can press at this link and watch an Animated PNG version of it. But be prepared, it has a size of 138 MB, so it will take some time to load it...

Gr.
Bram
