Recording Secretary Joanne Culin took note of the number present. In total, there were 11 present.

Minutes Approval
Recording Secretary Joanne Culin summarized the meeting notes from the September meeting, in which Daniel Lamb shared the technique of using satellite data to enhance storm surveys.

New Business
Eric Carpenter went over the results of the officer election that was held via a Google form. The new officers are:

Thomas Winesett for AMS President
Daniel Lamb for NWA President
Will Day for AMS Vice President
Logan Poole for NWA Vice President
Joanne Culin for Treasurer

There was discussion about how the recording secretary and corresponding secretary positions would be held as these were split votes. It was decided that David Cox would be Recording Secretary and Allen Leiberman would be Corresponding Secretary but some of these duties would be shared between the two.

Treasurer David Cox gave the treasury report, which we have $452.29. Since we continue to do virtual meetings we are not collecting dues at this time, as we are not incurring travel expenses for speakers or food for meetings.

Our guest speaker for the evening was National Weather Service meteorologist Logan Poole. Logan spoke about research he did investigating an anomalous wind gust that occurred at the Jackson Medgar Wiley Evers International Airport ASOS. A wind speed of 74mph occurred on June 2, 2021 at 4:05pm. This was a rather isolated event as no other severe weather occurred that afternoon in the entire state. No damage was noted and the only indication of this event was the measured wind gust. Logan showed the forecast parameters that there was some shear that day, and a little higher flow than a typical thunderstorm day. There was high surface based CAPE and mid level dry air, which may have helped this microburst occur. He was able to get low level wind shear data from the airport. He showed a trace of the pressure during the afternoon and there were two spikes: at 2059Z and 2105Z. He then stepped through what the wind speed and direction was leading up to the microbursts from several sensors around the airport property. Logan also provided an analysis of the storm in question using volumetric radar scans. He also showed the VAD wind profile and how the storm looked via visible IR satellite. He indicated how quickly it pulsed up and then down near the airport.

Adjournment
The meeting concluded around 8:15pm.

Minutes were submitted by Joanne Culin, Recording Secretary.
