Meeting Minutes for November 17, 2011

I.  Call to Order

The November NWA/AMS meeting of 2011 was called to order at 7:08 p.m. and was officially opened by Corresponding Secretary, Mr. Eric Carpenter.  The Chapter meeting was hosted by the FOX 40 TV News Station at One Great Place, Jackson, MS.  Guests were offered refreshments prior to the meeting.

II. Rolls

Recording Secretary Ms. Nancy Lopez took attendance, and the sign-in sheet confirmed 16 attendees. 

III. Minutes Approval and New Business

Treasurer, Ms. Joanne Culin gave an update on the financial report.  She collected $100 at the meeting and had formerly collected $55 with funds totaling $155.  Regular Chapter member dues are $20 and students are $10.  She had $15 remaining from last year’s funds.  She then briefed the group on the topics discussed from the September 2011 meeting for future Chapter events.   Future meeting topics included having a symposium, a visit from NCAR (the National Center for Atmospheric Research) or SPC (Storm Prediction Center), or a visit to the Planetarium.  However, the Planetarium is being remodeled, but it was suggested to ask former guest speaker Dr. Kosiba about viewing her work being featured in the IMAX “Tornado Alley” movie as an outing or as an inquiry to the Planetarium.

After new ideas were discussed for the Chapter, Mr. Carpenter turned the floor over to guest host Mr. Dave Roberts.  Mr. Dave Roberts is the Chief Meteorologist at TV news station Fox 40.  There are actually three stations housed at the WDBD site:  Fox 40, My35, and Me-TV, a classic television channel.  This is Mr. Roberts’ second time working in the Jackson area television market, after being away for several years while working in other states.  His enjoyment for southern storms kept him in the region, and he even worked five days straight at his Florida station after a prolonged power outage from Hurricane Charlie.  He stated his station does a lot with ratings and research, and is owned locally.  He then took the group on a tour of the studio into the Master Control, the official Stormtrack 40 Weather Center and the newsroom “where the magic happens” as well as the digital room.  Other parts of the station have a professional kitchen for cooking features, commercial production, and a newly-built patio is in progress.  The group chatted briefly after ending the meeting to allow Mr. Roberts time to prepare for his evening on-air weathercast.

IV.  Adjournment

The meeting concluded at approximately 7:55 p.m.---Nancy Lopez.

NORTH TEXAS

The November AMS/NWA meeting was held at the NWS Center Weather Service Unit, FAA Air Route Traffic Control Center. The meeting was hosted by Doug Reno and Charlie Hays and was very informative. The group received a rare behind the scenes tour of the center and its operations, as an added bonus for the group there happened to be weather in the area of the airport.

The December AMS/NWA meeting will be held on Tuesday, December 20, 2011 at 7:00 pm at the NWS West Gulf River Forecast Center/WFO Fort Worth/Dallas office located at 3401 Northern Cross Blvd.  Our speaker will be Bruce G. Thomas, Chief Meteorologist/National Spokesperson, Midland Radio Corporation. Bruce’s topic will be “From Texas to Kansas: Living and Working in Tornado Alley”.---Bobette Mauck.

 

OHIO UNIVERSITY

*OUCAMS held its last meeting for the quarter on November 8th.  We will resume regular meetings in early January.

Throughout the quarter the chapter has been going as a group to university football games.  An announcement was made at the November meeting that we would be meeting to go to the last game of the quarter.

Due to personal reasons, our VP will be stepping down.  The chapter officers has decided to hold reelections for this position at our first meeting back in winter quarter.  Nominations were sent in earlier this week to our advisor.  Students nominated will make a speech at the first meeting in January.

Scalia Lab had a logo contest in which students created a digital logo and submitted it for judging.  Judging was done during a full chapter meeting.  Our advisor has the final say and will announce the winning logo in January.

At the last full chapter meeting, I, as a student presenter, gave a talk on my experience of having a summer internship at WEWS News channel 5 in Cleveland.  I provided detail information as to how I went about applying for the my internship  and what I learned during my experience working with the weather department.  The other officers and I decided that it would be beneficial to give my presentation before the end of the quarter because most deadlines for news stations internships are over our winter break.  I wanted students to be aware of this before we left for the holidays.

Have a wonderful holiday season!---
Elise Dolinar.

OSWEGO STATE UNIVERSITY

Weatherfest

On November 5th, our club sponsored our local Weatherfest. Members of the college campus and local community were invited to come out to an afternoon filled with weather projects, like showing convection in a jar, refreshments, and a panel where both students and community members could ask questions about the meteorological world.

Chapter Meetings

The hot topic amongst our club meetings consisted of our club jackets and fundraisers to fund for trips to conferences. We are still waiting for volunteers from the art department here at SUNY Oswego to complete the update of our logo. The club is looking to order jackets at the start of the spring semester in 2012. Also starting at the beginning of the spring semester, the club is looking into selling Gertrude Hawk chocolate bars to help fund trips to conferences in the spring semester.

For more information on our club activities and upcoming events, visit our website at www.oswego.edu/news_weather/weather/---Daniela Pirraglia.

 

PENN STATE UNIVERSITY

In November, the Penn State Branch of the American Meteorological Society and National Weather Association (PSUBAMS) had the honor of hosting two esteemed speakers in one week!  First, Dr. Louis Uccellini, the Director of NCEP and AMS President-Elect, spoke about Extending Forecast Skill for Winter Storms.  He discussed how the forecasting process has advanced and how forecasts are now directly communicated to decision makers.  The following evening, Mike Eckert, a Senior Branch forecaster at HPC, gave PSUBAMS a broad overview of what the Hydrometeorological Prediction Center does.  Penn State Meteorology was thrilled to have the opportunity to host both of these great men!---Elyse Colbert.

 

RUTGERS UNIVERSITY

November 2011

During the month of November, The Rutgers University Meteorology Club has been continuing to plan for our trip to AMS 2012 New Orleans this coming January.  We have confirmed that a record 27 students will be attending this year's conference.  All trip deposits were collected and plane tickets were booked.  All the trip attendees successfully registered on time for the conference, including registration for the student conference.  The new dates for the trip are going to be from January 20th through January 26th.

We were expecting to have WABC-7 Meteorologist Bill Evans come and speak at an open event here at Rutgers on the 17th but the day of we were informed that Bill was having medical related problems and would not be able to make it.  The Club was able to get a hold of Meteorologist Jeff Smith and he volunteered under very short notice to come to speak to us in place of Bill Evans that same evening.  Our president Matt Drews presented the Englewood BOE Award to Dr. Passow before Jeff Smith started his talk.

The RU Meteorology Club had a day trip for interested members to visit the WPVI-TV (ABC-6) studio this month.  There were two days that members could choose to go, one on the morning of Friday the 18th and the other on the following Saturday morning (19th).  The trip was a big success with great feedback so we will likely try to plan something similar in future years.---Jeffrey Mart.

The November 2011 meeting of the chapter was called to order by President Brandon Hoving (National Weather Service Grand Rapids) at 7:30 pm. We began with an introduction of the Executive Board. Brandon and Nathan Jeruzal, Vice-President were present at the meeting. William Marino, Chapter Treasurer, was not able to attend due to recent surgery, and Robert Dale, Chapter Secretary, was unable to attend due to personal reasons. Approximately 20 people in total were in attendance at the meeting.

  

President Hoving discussed the results of the recent chapter elections. There was only one set of nominations submitted. That set of nominations was for the current Officers to be elected for another year. Numerous chapter members voted via email to elect the current Officers for the 2012 Chapter Year. The final election results for 2012 are as follows:

President – Brandon Hoving (National Weather Service Grand Rapids)

Vice-President – Nathan Jeruzal (National Weather Service Grand Rapids)

Secretary – Robert Dale (Skywatch Services)

Treasurer – William Marino (National Weather Service Grand Rapids)

President Hoving then moved on to announce the winners of the 2011 Summer Forecast Contest. The winners were:

-Warmest high Grand Rapids: Bill Marino with 97° on 7/22, the actual 97° on 7/20

-Warmest high Lansing: Jeff Wilhelm with 96° on 7/15, the actual 96° on 7/21

-90 degree days at Grand Rapids: Jon Shaner with 11 days, the actual 12 days

-90 degree days at Lansing: Dave Carmichael with 12 days, the actual 14 days

-Warmest water temperature: Brandon Hoving with 76° on 8/15, the actual 80° on 7/21

The winners were presented with an opportunity for a gift card for various businesses.

President Hoving then turned over the floor to Vice-President Jeruzal. A quick set of introductions was done of the members present at the meeting since there were a couple of new faces present. On behalf of the officers, a thank you was then given to Linda Paige, the new chapter webmaster, for the work she has done to update the chapter website. A thank you was also given to the chapter members for voting in the elections, and for the support they have given the chapter to make it succeed in the inaugural year.

Vice-President Jeruzal then presented a power point slide deck produced by Secretary Dale concerning Dual Pol Radar. The presentation of the Dual-Pol Radar information was given since the NWS Grand Rapids radar will soon be upgraded to Dual-Pol at the end of the month and beginning of December. The presentation was given at the meeting to give a brief introduction of Dual-Pol products, and how they will enhance the current radar suite of products. There are plans on having a more in depth Dual-Pol Radar talk at a near-future meeting.

Craig Woods, a retired Meteorologist from WOOD-TV 8 Grand Rapids, was then introduced to the meeting attendees as the main speaker for the meeting. Craig’s topic for the night was “Climate Change and CO2”. Craig presented a lot of information in the form of graphs and charts to support his view on Climate Change on the Earth. He also talked about the different ways that climate data has been researched in the past, prior to records being kept. A lot of this information was gathered from numerous sources, including academia, NASA, NOAA, and other experts in the field of climate. 

President Hoving thanked Craig for coming to the meeting and giving a very informative talk. An honorary membership for 2012 was given to Craig for presenting at the meeting. President Hoving then thanked everyone in attendance for coming to the meeting. He mentioned that the next meeting will occur after the first of the year with details to be determined.---Nathan Jeruzal.

SMOKY MOUNTAIN

The November meeting of the Smoky Mountain Chapter was held on the evening of the 14th. Around 12 people met first for dinner at the Downtown Grill and Brewery in Knoxville, and then 17 members convened at the University of Tennessee Ag campus to hear Dr. Kevin Birdwell (Oak Ridge National Laboratories) speak on "Wind Regimes in the Complex Terrain of the Great Valley of Eastern Tennessee". The following was an abstract of his talk: "This research was designed to provide a better understanding of physical wind mechanisms within the complex terrain of the Great Valley of Eastern Tennessee to assess the impacts of regional air flow with regard to synoptic and mesoscale weather changes, wind direction shifts, and air quality. Meteorological data from 2008-2009 were analyzed from 13 meteorological sites along with associated upper-level data. Up to 15 ancillary sites were used for background reference. Two-step complete linkage and K-means cluster analyses, synoptic weather studi es, and ambient meteorological comparisons were performed to generate hourly wind classifications. These wind regimes revealed seasonal variations of underlying physical wind mechanisms (forced channeled, vertically coupled, pressure-driven, and thermally-driven winds). Synoptic and ambient meteorological analysis (mixing depth, pressure gradient, pressure gradient ratio, atmospheric and surface stability) suggested up to 93% accuracy for the clustered results. Probabilistic prediction schemes of wind flow and wind class change were developed through characterization of flow change data and wind class succession."

Biography of Kevin: Kevin R. Birdwell graduated with a Bachelor of Science in Geography from Murray State University in Murray, KY in 1988 and worked part-time for the Carbon Dioxide Information Analysis Center at ORNL during 1988-1991. He was employed as a meteorological research associate for the National Oceanic and Atmospheric Administration's (NOAA) Atmospheric and Turbulence and Diffusion Division (ATDD) from 1991 to 2001. During that time, he received his Master of Science (1996) from Murray State University. Kevin completed his Ph.D. in Geography with an emphasis on environmental change, weather, and climate from the University of Tennessee, Knoxville in 2011. He has been employed with the Oak Ridge National Laboratory (ORNL) since 2001 as the manager of the on-site meteorological program, a meteorologist in the ORNL Emergency Operations Center, and as a researcher with the Computational Sciences and Engineering Division. His research has focused on complex terrain meteorology, air quality and dispersion, paleoclimates, and environmental change.---David Gaffin.

 

UNIVERSITY OF ALABAMA IN HUNTSVILLE

The fourth meeting of the UAH student chapter of the AMS for the academic year began at 5:30 on Thursday, 17 November, 2011. Vice President Adam Sherrer led the meeting, starting with a recap of recent events. These include the Yankee Candle fundraiser, which raised the chapter $200, and the community outreach event which several members volunteered for, which took place on November 12, 2011. This event, the Girls In Science and Engineering Day, involved approximately eighty third-fifth graders learning about weather and remote sensing, and taking part in an educational activity, making their own cloud charts.

The annual AMS meeting in New Orleans, which will take place on 21-26 January 2012, was also discussed, including important dates. A reception for UAH members is planned for Tuesday, 24 January. The chapter awards breakfast will also be held that morning. The Student Conference and Career Fair will be held on the 21-22 January, 2012. UAH AMS members that are around are asked to encourage prospective students to stop by the UAHuntsville Atmospheric Science Department table at the Career Fair. Also, the AMS WeatheFest will be held on Sunday, 22 January 2012 from 12pm-4pm. Webmaster Rob Junod is overseeing the chapter poster, and will be requiring content and photos from chapter members. Members are again encouraged to send pictures from chapter events for the chapter poster for
the annual meeting to UAHuntsvilleAMS@gmail.com.

Dr. Sundar Christophere, the Atmospheric Science department chair, will be hosted a NESSF proposal workshop on Friday, 18 November 2011 at 2pm in NSSTC 4065. This is a good career development opportunity that all students should attend. For the members participating in the community involvement event in the Jungle Bell 5K run on Sunday, 20 November 2011. Sign-ups are still available, with a donation fee of $25 will help benefit the Arthritis Foundation. A team has been formed by the name of “Rain Dears”, and interested members are encouraged to register at: http://2011jbrhsv.kintera.org . For members who have already registered, packets can be picked up at Fleet Feet in Jones Valley, or they can be picked up the day of the race.

Several outreach events are planned for the spring semester. A date of Saturday, 14 January 2012 was chosen to be the Habitat for Humanity event in order to help rebuild Northern Alabama after the 27 April 2011 tornado outbreak. More information will come at the next meeting. Our chapter's largest spring event will be the 6th Annual Tennessee Valley Severe Weather Poster Contest. Theme ideas are needed for the 2012 contest slogan and were discussed. Information on the contest will be distributed to north Alabama and southern middle Tennessee schools once their students return from the holiday break in January. Member Eric Anderson also discussed the joint activity being planned with the Earth Science Students Association in honor of earth week. Committees have been formed and AMS members are encouraged to volunteer their time to help make the day a success. A social outing was also discussed, possibly a hiking trip at the end of the semester. A doodle poll will be emailed to members to help choose a date and time.

There were fourteen members in attendance. The next meeting will be held on Friday, 13 January 2012 at 12pm.---Christina Branson.

PRESENTATION

David Roache, USF student in the Environmental Science and Policy program at USF, was invited to be the chapter’s November speaker after he was awarded the Chapter’s Dr. Dewey Stowers Merit Award earlier in the year. Roache is working towards his PhD on the topic of the relationship between global hurricane activity and large scale climate factors.  In addition to the Dr. Dewey Stowers Merit Award which Roache received in February, 2011, he has also received two Association of American Geographers Climate Specialty Group Student Paper Awards, in 2010 and 2011, as well as 1st place for the Graduate Student Paper of the Florida Society Geographers' Conference 2011. Roache is the author of two peer-reviewed papers on hurricanes (Monthly Weather Review, 2011; National Weather Digest, 2010) with his advisor, Dr. Jennifer Collins.

Roache started his presentation by noting El Nino and La Nina sea surface temperature and wind flow patterns, and he discussed how these relate to Atlantic basin tropical activity. He expressed that while it has long been known that El Niño and La Niña events directly impact seasonal tropical cyclone variability in the Atlantic basin, no prior research has found significant ENSO related impacts during Neutral conditions (Fig. 1). His research, under the guidance of advisor Dr. Collins (University of South Florida), pioneers a method of distinguishing between different variants of ENSO Neutral conditions, and from there identifies how these different Neutral phases directly impact Atlantic tropical cyclone seasons. Roache showed that small scale cooling and warming trends within overall ENSO Neutral conditions strongly relate to whether high or low activity tropical cyclone seasons occur in the Atlantic (Fig. 2), with particularly strong ties to intense hurricane landfall rates along the US Gulf of Mexico coastline. In closing, Roache discussed his plans to eventually conduct an analysis using data for the rest of the world, to gain a better picture of global tropical cyclone variability.

TREASURER’S REPORT

As of December 14th, 2011, the treasury stands at $781.59

CONCLUSION

A total of 46 WCFLAMS members, USF students and USF faculty attended the meeting. The presentation, "Analyzing the Variability of Atlantic Tropical Cyclone Activity during El Nino Southern Oscillation Neutral Conditions" was well received by audience members, who were curious to learn the results of the study. The presentation was also attended by a remote audience as the presentation was made available via livestream. Participants from all over the nation and globe attended including the Department of Geography, UCLA; Jagiellonian University, Poland; Cheyenne Space, Embry-Riddle Aeronautical University; Caribbean Institute for Meteorology and Hydrology, Barbados. In addition, local members who were unable to come in person were able to participate via Livestream.
