Minutes of the High Plains AMS/NWA Chapter Meeting
09 April 2014
The High Plains AMS/NWA Chapter held a face to face meeting in Norton, KS on April 9th. This gathering started at 11:30 AM, with a fine presentation by John Stopkotte, the SOO from North Platte, Neb. John’s topic was “Use of ZDR to anticipate tornado genesis”. He showed several examples of recent tornadoes, which had very short warning lead times. With the use of Dual-Pol radar images, John showed how some of the tornadoes spun up in as little of 4 minutes. The ZDR product can help identify this spin up. Increased shear promotes hydrometeor size sorting, and can be seen in the ZDR product. He also showed examples of when the forward flank region can often reveal signs of increased inbound winds, prior to the signs of tornado genesis. Many of these radar features using Dual-Pol products will need to be close to the radar site to identify them. One of the things to look for is the Forward Flanking Region containing mostly large rain drops, thus high ZDR.
Then we held the meeting after the presentation and before our meal. The meeting began at 12:45 PM, with 25 members present. Scott Bryant from Hastings, Neb. gave a treasury report. Since our Jan 8th meeting, there was $0.72 in deposits, from 3 months of interest, and $120.00 was spent to reserve the Lark restaurant for the upcoming High Plains conference. There was $5,712.06 in the Ledger, $1810.00 in the Jim Johnson Scholarship fund, with $3902.06 in the Checkbook. 2014 Dues were collected at this meeting.
