CENTRAL ILLINOIS

Meeting Summary, 6 May 2004 meeting of the Central Illinois Chapter of the American Meteorological Society.

The Central Illinois Chapter of the American Meteorological Society (CIAMS) held the third regular meeting of the 2003-2004 year at Weldon Springs State Park near Clinton on Thursday, May 6, 2004. 20 people attended. The meeting began at 7:45 PM by vice-president Chris Miller. Voting for chapter officers was conducted. Mike Kruk was overwhelmingly elected chapter vice president. Due to the number of people not attending the meeting and the number of possible absentee ballots the voting results for secretary and treasurer were too close to call. (On May 17, the results were announced with Mike Spinar elected secretary and Maria Peters elected treasurer.) Chris also announced that the next meeting date has not been determined but it will be a joint meeting with the Indiana AMS chapter at the Beef House in Covington, Indiana. The Regional Conference startup meeting will also be taking place in the next few weeks. Mike Kruk contacted Maria Peters for the treasurer's report. The chapter has $4611 on account. The chapter has also been advised by AMS headquarters that it does not have to file taxes with the IRS. Mike Spinar gave an update on the education committee.

Dr. Michael A. Palecki of the
Illinois State Water Survey / Midwest Regional Climate Center

The featured speaker for this meeting was Dr. Michael A. Palecki of the Illinois State Water Survey / Midwest Regional Climate Center. Mike's topic was "Drought in the US: Are conditions changing?" Mike began his presentation by noting the effects of the frequent snow droughts and late summer season droughts in the upper Midwest: severe soybean losses in 2003, winter tourism losses, lost shipping costs due to low lake levels in the Great Lakes, and regional crop losses that seem to go unnoticed. The big question is why is this happening? Mike showed that the large shifts in precipitation could be a result of the two oscillations in ocean temperatures. The Pacific Decadal Oscillation (PDO) and the Atlantic Multidecadal Oscillation (AMO) were defined and their impact on Midwest drought explored. Mike noted that less drought occurred in the US when the AMO was negative (cooler North Atlantic Ocean). He also noted that the current AMO is positive which infers continued drought for the Midwest.

After questions the meeting adjourned at 8:42 PM.---Tom Bellinger.

CHICAGO

The Chicago Chapter of the American Meteorological Society annual banquet was held on May 1, 2004. The guest speaker was Dr. David A. R. Kristovich of the Atmospheric Science Section of the Illinois State Water Survey, Department of Atmospheric Sciences, University of Illinois. Dr. Kristovich's presentation was entitled "Intimate Looks at Lake-Effect Storms: Field Project Experiences."

Lake-effect snow has a significant impact, both positive and negative in the Great Lakes Region. Negative impacts include, but are not limited to, building damage, air transportation delays and cancellations, power outages, ground trasportation delays and accidents and snow removal injuries including slip and falls. Some negative impacts depend critically on the time of the day of the occurrence. Positive impacts from lake-effect snow include increased revenue from winter recreation, supply sales and repairs to damaged structures or equipment.

Lake-effect field projects are conducted to help enhance operational global/regional numerical models that are capable of simulating mesoscale circulations. The field studies produce high quality observations capable of validating the mesoscale numerical model results. Field measurements allow for the collection of data where it would have otherwise been unavailable. Operational models are reaching an awkward age. Resolutions of 1 to 5km are too small for most convective parmeterizations and too large for many explicit calculations. The model limitations creates a need for better parameterizations.

Common goals of the lake-effect snow field projects include developing parameterizations, understanding new phenomena, developing a high quality data set to test numerical model simulations and to take observations of characteristics not commonly available (i.e. NOx concentrations, CCN spectra, etc.).

Recent lake-effect field projects have included the University of Chicago Lake Snow Project of the 1970's and 1980's, the LOWS project of the 1980's, the National Weather Service Lake-effect Snow project during the 1990's, Lake-ICE in 1997 and 1998 and the recent GLICAF (Great Lakes Ice Cover - Atmospheric Flux Project).

Much has changed in lake-effect field projects since the 1970's. Some changes include enhancements in aircraft flight planning and instrumentation, radar techniques, other remote sensing facilities, improved sounding abilities and better questions being asked by those involved in the projects.

Hot topics in lake-effect storm research include microphysical processes, lake-to-lake bands, natural cloud seeding, upscale energy transfer, rediation processes, diurnal evolution in organization of snow bands and spatial/temporal variations in ice cover.

Dr. Kristovich's most recent field project, GLICAF, strives to understand atmospheric boundary layers and surface exchange processes that occur over ice fields of varied concentration on mid-latitude lakes. Reasearch is also intended to quantify the relationship between turbulent heat fluxes and different pack ice concentrations.

GLICAF field work was conducted between February 18, 2004 and March 2, 2004 over Lake Erie. The aircraft utilized for the field project was the University of Wyoming King Air. Six flights produced a tremendous amount of data that is now being reviewed. The six flights included one test flight, three positive flux scenarios, one negative flux scenario and one lake breeze case.

Dr. Kristovich concluded his presentation by showing video footage of some of the aircraft passes over Lake Erie.---Mark T. Carroll.


LOS ANGELES

Dr. Roger Wakimoto Talks About the Legacy of Dr. Ted Fujita and Mesoscale Analyses Techniques

The members of the Los Angeles chapter were honored to have at their annual awards banquet Dr. Roger Wakimoto, UCLA professor of Atmospheric Sciences. Dr. Wakimoto presented a fascinating look at the life and career of Dr. Ted Fujita, "Mr. Tornado" and how he helped Roger in directing his own illustrious career in mesoscale phenomena. Roger decided to do his graduate work at the University of Chicago because that was where the most exciting research was being done at the time. As a student of Fujita, Roger learned from the master. Years later, Roger along with Greg Forbes helped organize the Symposium in Tribute to Dr. Tetsuya T. Fujita at the 2000 Annual Meeting of the AMS in Long Beach, California. Summarizing Fujita's remarkable career, Roger noted that Fujita's research and contributions to atmospheric sciences "were seminal and are still being widely used today." Fujita will always live through the mesoscale analysis techniques that he developed. His investigations are numerous and have led to great benefits to society, especially in aviation. Wakimoto called Fujita the "greatest meteorological detective," for his many scientific breakthroughs using mesoscale analysis techniques.

Dr. Wakimoto also showed the banquet guests how his own career developed from his early days with Dr. Fujita at the University of Chicago to his years spent at UCLA. From early photos at the University of Chicago, to later examples of mesoscale storm studies at UCLA, we followed Dr. Wakimoto's research from air pollution measurements using lidar, to Doppler radar work in Project Vortex, highlighting his work on downbursts, hurricanes, waterspouts, tornadoes and bow echoes. Roger shared some of his latest work dealing with the internal structure and genesis of tornadoes in supercells and various kinds of meso-cyclones. When asked whether tornadoes build up from the ground or down from the cloud, Dr. Wakimoto gave examples of both features. What still puzzles forecasters is how some large, powerful meso-cyclones produce weak tornadoes, while under supposedly less favorable conditions, stronger tornadoes are possible. The local chapter was very appreciative of the presentation and the presence of Dr. Wakimoto and his lovely wife Jina.

In appreciation to Roger's talk and being a special guest, he was given the book "Isaacs Storm". When asked, "We hope you don't already have this" His reply was "Yes, but not in hardcover".---Steve LaDochy.


OMAHA-OFFUTT

The Omaha-Offutt chapter of the AMS held its May meeting on May 25, 2004, a lunch meeting at Lo Sole Mio Villa restaurant in Omaha.

At 11:37 AM chapter President Jeremy Wesely called the business meeting to order.

Recording Secretary John Roth announced 26 members and guests were in attendance. He then read the minutes from the April meeting. A motion to accept the minutes was made by Bill Courtemanche and seconded by Bruce Telfeyan, and the minutes were accepted.

Treasurer Matt Sittel presented the treasurer's report. There was 1 new membership paid prior to the meeting, bringing the total membership for the year to 61.

John Eylander presented the education committee report. Committee members have completed high school speaking engagements for the current school year. Work is ongoing with the Omaha Children's Museum, and will continue over the summer.

Old business:
Bruce Telfeyan of the election committee thanked committee members Bill Courtemanche and Daniel Nietfeld for their work in getting nominees for each office, and announced the nominated candidates for the 2004-2005 year. He solicited additional nominations from the members present; none were received. He then passed out the ballots to members to cast their votes. Ballots would be collected and the results announced following the meal.

New business:
None.

Speakers:
Following lunch, two chapter members made presentations.
Daniel Nietfeld, science and operations officer at the National Weather Service office in Valley, gave a talk entitled "April 18 2004 Non-Supercell Tornadoes". There were three of these reported that day, in Pierce and Wayne Counties, Nebraska. Also known as "landspouts", they often occur in multiples, are not as well organized as supercellular tornadoes, and, though they have been known to reach F3 strength, are more typically F0 to F1. They do not show up well on radar returns, a point Daniel illustrated by showing radar imagery from that day. He also showed some pictures from the damage survey of the (traditional) tornado that hit Hallam NE on May 22, which resulted in the tornado being upgraded to F4, and showed radar images from that event as well.

Dave Keller, programmer in the Technology Exploitation Branch of Air Force Weather Agency, showed his Bolt of Lightning Technique for forecasting areas of thunderstorms. The technique is broken into causes, factors that will cause thunderstorms to form over an area, and filters, or factors that inhibit thunderstorm formation, to cut down on false alarms. The cause factors used in the technique are instability and lack of capping in the boundary layer, presence of elevated instability (based on maximum value of Showalter index from lifting mid-level parcels, in the region about 75 millibars above the LCL), and upward forcing with a nearly saturated sounding. The filtering factor used is to require relative humidity above the LCL to be greater than 90 percent, since two thirds of all lightning occurs in this condition. The technique works well except over mountains, so Dave is developing a mountain technique as well.

Following the presentations, Bruce announced the results of the election. Jeremy Wesely was reelected President, current Treasurer Matt Sittel was elected Vice President, Jeffrey Johnson was elected Corresponding Secretary, John Roth was reelected Recording Secretary, and Karen Harder-Sittel was elected Treasurer. Jeremy thanked the outgoing officers from the past year, and thanked Bruce and the election committee for running the election.

The meeting was adjourned at 1:04 PM.---John Roth.


PACKERLAND

Meeting Minutes - May 6, 2004

On Thursday, May 6, at the UW-Green Bay Christie Theater, fellow PCAMS member Katie Hemauer presented: "Analysis of Climate Prediction Center's Long Lead Seasonal Temperature Forecasts for Wisconsin". The alternate title was "What Can America's Dairyland Milk Out of the Climate Prediction Center's Seasonal Climate Outlooks?" A large crowd of PCAMS members, students, and the public attended the session.

Katie discussed the results of an independent study that she participated in last fall under the direction of Chapter President and UWGB Professor, Dr. Steven Meyer. Numerous benefits can be derived from predicting future temperatures. Examples are tourism dollars, farming issues, and predicting snow plowing costs. In summary, long-lead time spring forecasts are the least accurate, but short-lead time forecasts hold up fairly well. All seasonal temperature forecasts could use some improvement, but tremendous strides have been made in the last few years. An excellent question and answer session followed Katie's presentation.

In PCAMS business, the new officers and directors for 2004 were announced and introduced. President: Dr. Steve Meyer, Vice President: Jeff Last, Secretary: Dale Walker, Treasurer: Peg Staudenmaier, Directors: Gary Austin, Dr. Jim Brey, and Tom Mahoney. A business meeting will be scheduled during the next few weeks to discuss chapter issues and future meeting topics.---Dale Walker.

TWIN CITIES

The Twin Cities Chapter of the American Meteorological Society met on the evening of May 20th, at the Lake Susan Park Pavilion for an end of season picnic and presentation by Eve Iverson, who works in the Meteorology Department at Cargill, Inc.

About 20 members attended the picnic on a lovely Spring evening. The members dined on a catered BBQ meal, with friends and family in attendance.

New officers for the 2004-2005 year were voted on and approved. The new officers are

President - Rich Naistat (NWS Twin Cities/Chanhassen)
Vice President - Doug Dokken (St. Thomas University)
Secretary/Treasurer - Chris Bovitz (National Operational Hydrologic Remote Sensing Center - NWS)
Newsletter Editor - Kurt Scholz (St. Thomas University)

The evening's presentation from Eve Iverson, Cargill, Inc., featured handouts and displays of the Cargill facility and the many reaches of Cargill into food production in the United States and across the world.

Mrs. Iverson spoke about the affects of weather on Cargill. Cargill, Incorporated is an international provider of food, agricultural and risk management products and services, with 101,000 employees in 60 countries. Crops, transportation, and energy consumption are only a few areas with significant weather impacts. Heating degree days, growing degree days, and anomalies are just three ways to equate weather to production and consumption of numerous commodities.

Mrs. Iverson became interested in weather when lightning struck the church steeple a block away from her home in Hanover, PA. After moving to Arvada, CO, & experiencing a Chinook wind that literally blew her over, weather took on a more personal relationship. Math and science were her strong points and a high school trip to NCAR during their hail research programs intrigued her. After her second year of college as an architectural engineering major at Penn State, Eve headed west.

Short on funds, she landed a job at Cargill, Incorporated, in 1977 as the Weather Clerk/Met Tech in their newly created Meteorology Department. Ten years later she returned to college to complete her undergraduate degree at Augsburg College, majoring in MIS and with a minor in Economics. Eve works closely with the Crop and Economic Analysis groups at Cargill, as well as interfacing with computer support groups. Data management and support of the meteorologist are a large part of her job.

A brief question and answer session followed, mainly centered on the fact that Cargill is such a large company, yet remains privately owned and operated. This creates a very family oriented work environment, according to Mrs. Iverson.---Seth Binau.


VIRGINIA PIEDMONT

The Revival of the Virginia Piedmont Chapter of the American Meteorological Society

After over a decade-long hiatus, January 2004 marked the revival of the Virginia Piedmont Chapter of the American Meteorological Society as the chapter's poster was presented at the Local Chapter Poster Session of the 84th Annual Meeting in Seattle, Washington. Located in historic Charlottesville, Virginia, the Virginia Piedmont Chapter was officially formed in July 2003. The chapter is currently comprised of graduate students and distinguished faculty of the University of Virginia Department of Environmental Sciences. Current activities include bi-weekly meetings consisting of presentations and discussions of ongoing research topics in the field of atmospheric science by chapter members and invited guests.

To fulfill our goal of community outreach, several chapter members traveled to two local schools in the Charlottesville area during April 2004. First, members of the chapter gave a weather presentation covering instrumentation, data, and forecasting to a 4th grade class at Venable Elementary School. Several female members also visited the Village School, an all-girls' private middle school, discussing general meteorological and forecasting principles to the 5th grade class (Figure 1). This visit provided an excellent opportunity for the female students to learn what career paths are available to women in atmospheric science. The students were excited and appreciative of the members' visits (Figure 2).

Future plans for the chapter include expanding the membership to more Central Virginia residents and undergraduate students at the University of Virginia. Development of a research symposium is in the works to expose undergraduates to current research in atmospheric science. Preparation is also underway for participation in a university-sponsored "Science Day" in Fall 2004. For information concerning the Virginia Piedmont Chapter, including membership and events information, please contact chapter President Daniel Carré (carre@virginia.edu). Other officers include Nicole Kordziel (nmk4a@virginia.edu), Lori McGuire (ldm3a@virginia.edu), Tom O'Halloran (tlo5c@virginia.edu), Erin Potter (epotter@virginia.edu), José D. Fuentes (jf6s@virginia.edu), and Jennie Moody (moody@virginia.edu).
