Mr. Daniel Andreev who served nine years as a meteorologist with the Bulgarian Air Force provided a presentation entitled "Some Aspects of the Weather Forecast Presentation Technology in Bulgaria, Europe. Mr. Andreev came to the United States in 1998 and now works with the Acxion Corporation developing software.

Government sector meteorology in Bulgaria has three branches, the National Institute of Meteorology and Hydrology, the Air Force Meteorology Center and the Civil Aviation Authority Meteorology Center.

Private sector meteorologists have formed a company called TVMET. TVMET prepares and presents weather forecasts for television, the Internet, mobile devices and meteorological support by subscription and on demand. TVMET also trains television weather forecast presenters.

Weather forecasts and graphics are prepared by TVMET for Bulgarian television (BTV) and other television stations in European countries, as well as for newspapers. TVMET makes weather forecasts and data available via the Internet. Current weather conditions, updated every minute, are available on websites such as or Cameras provide views from towns and tourist areas on the TVMET website. Other data available on the TVMET website include sea water temperatures, wave conditions, ski conditions, 5 day forecasts for select locations in Bulgaria and climatic information for 23 areas.

TVMET provides mobile broadcasting via cell phones, I-pods, etc. Animated maps and current conditions from 30 locations in Bulgaria are available by remote access.

TVMET's subscription and on-demand services are provided to many clients including hotels, tourist spots, television channels and commercial and scientific organizations. The Bulgarian government purchases data and forecasts from TVMET.

The forecast process for TVMET includes data collection from 34 automated sites in Bulgaria via the Internet. Some of the automated sites collect data related to erosion measurement, soil moisture, soil temperature and salinity. Global models such as the AVN, LOOPS, GRDAS and ETA are utilized by TVMET meteorologists during forecast preparation. Climatology is also critical for generating maximum and minimum temperature forecasts. Graphics are produced for television stations that include temperature, pressure, wind, cloud, precipitation and weather condition information.

All of the information collected and disseminated by TVMET is accomplished by a staff of two meteorologists, both of which were former Bulgarian Air Force meteorologists.

Mr. Andreev completed his presentation by discussing some research he has been involved with concerning Unsteady Flow Visualization or Vector Fields Visualization. Unsteady Flow Visualization can be explained by spot noise (single to multi-point), Line Integral Convolution (LIC) or a combination of spot noise and LIC.---Mark T. Carroll.

DC Chapter. The 21 March 2005 meeting, hosted by Science Applications International Corporation (SAIC) in Tyson's Corner VA, included a complimentary dinner, (courtesy of SAIC), a short business meeting and a presentation by Dr. John Marburger III, Science Advisor to the President and Director of the Office of Science and Technology Policy (OSTP).

During the business part of the meeting, Vice Chairperson Jason Samenow said the April 2005 meeting would be held at the new Marian Koshland Science Museum located at the National Academy of Sciences in Washington, DC. Jason also announced that the DC AMS is a sponsor of the upcoming meeting, 29-31 July 2005 (more information is available at Meetings Link). The Weather Channel's Winter Weather Expert Paul Kocin as well as many other meteorologists will give educational presentations that should entertain/inform weather enthusiasts and veteran meteorologists alike. Chapter Chairperson Chris Moren encouraged members to renew their membership, to volunteer to be Chapter Officers (since several of the current officers will be stepping down), and to volunteer to be Science Fair judges. He also asked members to spread the word that the deadline for submission of applications for the DC AMS Scholarship is 1 May 2005. Chapter member Fred Klein spoke a few minutes on the upcoming Oceans 2005 that will be 19-25 September 2005 in Washington DC. The theme for the conference is "One Ocean" so the focus will be global oceans and more information is available at

Dr. John H. Marburger, Director, Office of Science and Technology Policy, was confirmed in October 2001 and serves as Science Advisor to President Bush. Dr. Marburger also co-chairs the President's Council of Advisors on Science and Technology (PCAST) and supports the President's National Science and Technology Council (NSTC).

According to the OSTP web page ( ), Congress established OSTP in 1976 with a broad mandate to advise the President and others within the Executive Office of the President on the effects of science and technology on domestic and international affairs. The 1976 Act also authorizes OSTP to lead an interagency effort to develop and to implement sound science and technology policies and budgets and to work with the private sector, state and local governments, the science and higher education communities, and other nations toward this end.

OSTP's continuing mission is to serve as a source of scientific and technological analysis and judgment for the President with respect to major policies, plans, and programs of the Federal Government OSTP is authorized to: Dr. Marburger focused his remarks on the current U.S. actions to address climate change. He began his remarks by stating that, prior to President Bush's election, the Senate had effectively already voted against the Kyoto Protocol* and that the President opposed Kyoto since it would risk harming the U.S. economy. To obtain a credible assessment of climate change science to serve as a basis for Adminstration climate policy, President Bush turned to the National Academy of Sciences (NAS). The NAS published their report in mid-2001 (the full report is available online at

Marburger highlighted President Bush's June 11, 2001 speech on climate change in which the President stated that (1) the earth is warming, (2) there is a natural greenhouse effect that contributes to warming, and (3) that concentrations of greenhouse gases, especially CO2 have increased substantially due to human activities. The President acknowledged the uncertainties in climate change science but indicated, we can begin now to address the factors that contribute to climate change. In the speech, the President announced that he had set up the U.S. Climate Change Research Initiative to study areas of uncertainty and, more importantly, to identify priority areas where investments can make a difference. The speech is available online at: (,

Dr Marburger praised the Climate Change exhibit at the new Marian Koshland Science Museum, but said it fails to count nuclear power as an option to the carbon dioxide-based power that drives the U.S. economy. It is clear, he stated, that the effect of carbon dioxide is so great that we won't make a big impact on global warming until we make big changes in energy technology. We must explore such energy sources as nuclear, wind, solar, and hydrogen energy, which don't add carbon dioxide to the environment. President Bush has set goals and priorities, and funded new clean energy technology development that will break the link between the economic production and carbon dioxide emissions. The President and his Cabinet are aggressively pursuing these policies.

[*NOTE: The Kyoto Protocol to the United Nations Framework Convention on Climate Change (UNFCCC) ( ) is an amendment to the UNFCCC international treaty on global warming. It also reaffirms sections of the UNFCCC. Countries which ratify this protocol commit to reduce their emissions of carbon dioxide and five other greenhouse gases, or engage in emissions trading if they maintain or increase emissions of these gases. It was negotiated in Kyoto, Japan in December 1997, opened for signature on March 16, 1998, and closed on March 15, 1999. The agreement came into force on February 16, 2005 following ratification by Russia on November 18, 2004.]---Lauraleen O'Connor.


March 2005 Minutes

Mr. Tim Garner: (Spaceflight Meteorology Group) Lead Forecaster

March's meeting was very unique and poignantly hit all of us Americans-Houstonians both in our hearts & at home. Mr. Garner discussed NASA's Spaceflight Meteorology Group's (SMG) efforts in the recovery of the doomed re-entry of the Shuttle Columbia (STS-107) on February 1st, 2003. Their goal was to recovery as much as humanly possible by tracking the debris field via the WSR-88D radar. Mr. Garner shed light on his group's mission those weeks following that tragic day.

After explaining what ultimately caused the disaster, which was the damaged left wing (disintegrating upon re-entry) caused by a dislodged fuel tank panel striking the wing's edge upon ascent, Mr. Garner got into what his office had to do in support of the recovery mission. They virtually had to re-construct the atmosphere by mapping the winds along the orbiter's re-entry trajectory. Massive amounts of data collection, from profiler data to GOES satellite data, was utilized in this intensive reconstruction which took months to complete. He also dismissed the "Purple Bolt Theory" as a photographic mirage/artifact. He discussed the 88D's logistical issues when they were trying to piece together the forensic puzzle of what was occurring at 200,000 feet up (63 Km), or at the level at which the orbiter disintegrated, the morning of February 1st. Some of the issues included non-uniform radar clocks, radars out of calibration, and trying to match up different VCPs (Volume Coverage Pattern) across the vast network….plus the fact that the radar cannot "see" anything above 70,000 feet. Fine particles of aluminum-oxide particles (needles) that melted and then re-cooled sifted downward in the mean flow and this is what the Doppler Network was remotely sensing. This debris path extended from western Texas to eastern Florida over a span of 24 hours.

Tropospheric and mesospheric analyses were performed to determine this debris field behavior. Other tools used were the SABER (IR radiometer on satellites), METeor radars, and the climatology GRAM-99. After the atmospheric reconstruction was complete the basic synopsis was that, other than some minor mid-level turbulence, the orbiter encountered a normal environment required for a safe re-entry; or all parameters were within 1 to 2 standard deviations (1-2 s).---Patrick Blood.

The Omaha-Offutt chapter of the AMS held its March meeting on March 18, 2005, at the Garden Café restaurant in Omaha. There were 35 members and guests in attendance.

At 6:38 PM chapter President Jeremy Wesely called the business meeting to order.

Recording Secretary John Roth read the minutes from the February meeting. A motion to approve the minutes was made by Phil Johnson and seconded by Fawn Morley, and the minutes were accepted.

Jeremy announced that chapter newsletters and forecast contest forms were available. John announced the results of February's forecast contest. There was a tie, so Joe Hanser and Jen Roman were declared co-winners. Jeremy stated that Matt Sittel was making up coupons for reimbursing contest winners.

Fawn Morley stated that the education committee had reviewed three applications for minority scholarships and passed them up to the national headquarters. Evan Kuchera announced that he and John Eylander would be speaking at the Omaha Children's Museum on April 9 on the subject of severe weather safety. Jennifer Roman announced that the first two meetings of Weather Explorer Post 999 had been held. The first meeting featured discussions on winter weather, and the second featured a tour of the KMTV television studio. Sarah Walters was presented an Explorer Post 999 T-shirt as thanks for hosting the tour. Phillip Johnson reported two prizes had been awarded at the Metro Omaha science fair. Two more science fairs were coming up on April 2nd, Iowa State in Ames and Greater Nebraska in Nebraska City. Phil also stated that they were not able to acquire weather radios as planned, since they had to be purchased in bulk. So the money had been spent for books as prizes. Brian Waranauskas offered to donate two weather radios as science fair prizes.

Old business:

New business:
Jeremy announced the April chapter meeting would be held on April 12 in conjunction with the AFWA Heritage Luncheon. Mr. Art Gulliver would be one of the speakers at the luncheon, speaking on the history of the chapter as it reaches its fiftieth anniversary. Tours of AFWA would follow. Anyone interested in attending who is not on the chapter distribution list should get hold of Jeremy, since important information on the event would be forthcoming via email. A list of those planning to attend would be needed in advance to procure tickets and schedule the tours. Col John Lanicci also added that the visitor reception center would be moved to the SAC Gate by then, so visitors would need to enter by that gate.

With no more business, a motion to adjourn the business meeting was made by Fawn Morley and seconded by Joe Hanser, and the business meeting was adjourned at 6:51 PM. Dinner was then served.

Following the business meeting and dinner a presentation was made by Mr. Tim Samaras of Applied Research Associates in Littleton, Colorado. His talk was entitled "Stable Sensors for Tornado Core Measurements." Mr. Samaras described the instrument he designed for this purpose, the "Hardened In-Situ Tornado Pressure Recorder", or HITPR. It is a shallow cone-shaped probe designed to remain stationary in high winds and withstand pelting of wind-driven debris and hail. It contains pressure, temperature, and humidity sensors and a data recorder, powered by on-board batteries. The design allows accurate measurement of static air pressure, independent of the wind speed blowing over the probe. Variation of pressure at different positions on the probe also allows measurement of wind speed and direction. Mr. Samaras explained how it is used. He places the probe in the expected path of a tornado, turns on the sensors and recorder, and after passage recovers the probe and downloads the recorded data. He has had success with his HITPR probes over the past three years, including capturing the largest one-minute pressure drop ever recorded, 100 millibars, recorded as a tornado passed directly over a probe, near Manchester, South Dakota, in June 2003. He showed video footage of the storm, with the pressure trace taken from the probe super-imposed on the video. Several other videos of near misses were also shown. In 2004, he added a "Media Probe" to the mix. Designed similarly to the HITPR, but larger, it contains seven video cameras, six horizontal pointing in 60 degree increments, and a vertical camera. He showed some remarkable video footage shot from these cameras as the outer wall of a tornado passed by.---John Roth.


Meeting Minutes-March 10, 2005

A near capacity crowd of chapter members and students met at the University of Wisconsin Green Bay Christie Theater, to hear a presentation titled "TSUNAMI!" from Allen Paul Price, an Associate Professor of Geography and Geology at the University of Wisconsin-Washington County. Professor Price is an expert in the case study approach to teaching science and geography. The following is a brief summary of his presentation.

The magnitude 8.1 earthquake (some estimate as high as 9.3) that struck Indonesia on 12/26/04 occurred about 30 kilometers below the surface, and covered an area 1200 kilometers x 100 kilometers. The quake shifted the North Pole 2 centimeters, and sped up the earth's rotation. The wave, or Tsunami, created by the quake traveled at up to 620 miles per hour in the ocean. Unfortunately, coastal zones tend to be areas that are highly populated. Current estimates are that between 228,000 and 310,000 were killed by the waves.

Tsunami's can be triggered by several factors, such as underwater landslides, underwater explosions, volcanic eruptions, meteorite impacts, and earthquakes. Basic earthquake theory was discussed. The Indonesian quake lasted about 8 minutes, an extreme length of time. Damage factors for Tsunami's include, the source and magnitude of the quake, ocean levels, wave travel distance, slope of the shoreline, coastal configuration, and the human element.

The primary effect of the wave is impact damage and flooding. Secondary effects include, habitat destruction, and water/soil contamination. Tertiary effects are, displacement of people, loss of jobs, etc. Unfortunately, there was no warning system in place for the area that was devastated. Warning systems are being developed and are available. This, combined with better planning, could help to avoid the tremendous loss of life if a future Tsunami occurs, anywhere on the earth.

The presentation wrapped up with a question and answer session. Professor Price was given an ever-popular AMS coffee cup for his excellent efforts.

In PCAMS business, the local officers were introduced by President Steve Meyer. The next meeting will be on April 14th, when Jeff Last conducts the annual storm spotter training. On May 5th, Professor Meyer will make a presentation on long-term weather forecasting.---Dale Walker.


Integration of Local, State, and Federal Resources in Emergency Management

On March 11, 2005, the Palmetto Chapter of the American Meteorological Society (PAMS) hosted the 11th Annual Mini-Technical Conference at the South Carolina Department of Health and Environmental Control (SC DHEC) in Columbia, South Carolina. Chapter Vice President, Allen Weber of Savannah River National Laboratory (SRNL), moderated a special session on the Graniteville train crash and resultant chlorine spill in Aiken County, South Carolina on January 6, 2005. The SRNL's Atmospheric Technologies Group (ATG) and the National Weather Service played an integral part in the response and mitigation of the chemical release by providing timely observations and numerical simulations of the meteorological conditions throughout the event.

Chris Alverson of the Safeguards, Security, and Emergency Services Division at the Savannah River Site and a member of the Graniteville Volunteer Fire Department presented operational concerns from an emergency responder's perspective including actual 911-calls, personnel issues, and the interaction of first responders with local, state, and federal resources, particularly the SRNL Atmospheric Technologies Group (ATG). An existing mutual aid agreement with Aiken County allowed ATG meteorologists, Charles Hunter, Matthew Parker, Robert Addis, Robert Buckley, and Allen Weber, to provide atmospheric conditions and forecasts through the Regional Atmospheric Modeling System (RAMS, version 4.3.0) and two transport models (LPDM and PFPL).

At 0240 LST (0740 UTC), over 90 tons of liquid chlorine, cresol, and sodium hydroxide were released into the environment over a short time span. The liquid chlorine, highly volatile at standard atmospheric conditions, rapidly vaporized to form a dense and highly toxic airborne cloud. Using meteorological data from a local network of observations stations, and output from an operational mesoscale forecast model, ATG scientists applied atmospheric transport and dispersion models to estimate potential downwind hazards. Initial hazard estimates were performed with ATG's Puff/Plume code, a segmented trajectory Gaussian dispersion model. Additional plume transport calculations were performed with a Lagrangian particle dispersion model (LPDM), which provides full utilization of 3-dimension wind forecasts provided by the operational mesoscale model. Results from the models were posted to a designated external web site, enabling local emergency management officials and the SC DHEC to assess the appropriateness of evacuation orders within the significant threat area over the several days of response and recovery operations that followed the derailment.

The ATG also conducted a detailed post-accident analysis of the chlorine release. The operational configuration of the mesoscale forecast model uses a 2-km horizontal grid resolution. To account fully for local topographic characteristics, the model was modified to include nested grids of 500 m and 125 m centered on the accident site. Fine resolution topography from digital elevation maps was used to characterize the Graniteville area and archived analyses from the Rapid Update Cycle (RUC) model provided initial and lateral boundary conditions at 3-hr intervals. Simulated values of wind speed and direction were compared with regional observations and were seen to capture the flow for this day. Application of the fine-scale meteorology was used to illustrate pollutant transport in a general sense over an 18-hour period following the accident, indicating transport to the northeast. In addition, the Hazard Prediction and Assessment Capability (HPAC) was used to simulate migration of the dense gas immediately following the accident. The predicted plume location is supported by the location of fatalities that occurred in the immediate area, as well as visual evidence of damage to plant life. Based on the detailed modeling, the dense chlorine plume was gravity driven and flowed toward lower elevation to the southwest and against the prevailing wind direction. Subsequent transport was toward the north-northeast as the dense cloud became more dilute and subject to behavior as a passive gas.

The National Weather Service's Columbia office was represented by Meteorologist-in-Charge, Bernard Palmer. Mr. Palmer detailed the NWS wind forecasts for the accident and the warnings that were given to the affected area and the general public through the NOAA Weather Radio. Mr. Palmer noted that this was the first time in recent memory that a non-weather emergency was disseminated via Weather Radio. These notifications were modified as the accident scenario played out over a period of many hours.

The Mini-Technical Conference also highlighted the ideal relationships that should exist between the private, public, and government sectors of the meteorological and climatological communities, which Matthew Parker of SRNL emphasized in his presentation on the American Meteorological Society's Commission on Weather and Climate Enterprise (WCEC). The AMS is poised to improve communication through the WCEC, which is the first new Commission in the last 30 years. Mr. Parker's work is a reflection of the dedication of ATG founders, Todd Crawford and Ben Rusche, (in attendance at the meeting), to the integration of weather science across a broad spectrum of disciplines that continues to foster the professional growth of the atmospheric science community in South Carolina.---Jason Caldwell.

Summary of the March 23rd, 2005 SEACAMS Meeting The March meeting of the Southeast Arizona Chapter of the American Meteorological Society was attended by about 22 members and guests. Those who attended this meeting were treated to a tour of the KVOA studios, a local NBC affiliate, given by Chief Meteorologist Jimmy Stewart and one of the studio directors. Jimmy Stewart gave a demonstration of how he does his live weather broadcasts and showed us some of the latest technologies in broadcast meteorology. He explained how the graphics work and what is done to help the warnings, put out by the National Weather Service, to be disseminated to the public. The studio director gave us a tour of what goes on behind the scenes during a news broadcast, as well as 24 hours a day. There are many involved in making sure that our local NBC station has a continuous flow of shows, news, and spots for commercials, which is how they make their money.

On a separate note, Mary Glueck and Carl Noggle represented SEACAMS in the Southeast Arizona Science and Engineering Fair on March 15, 2005. They were special awards judges and chose the winner of the special AMS award.---Dawn Fishler.

After our speaker and general business, the members went up to the 12th floor for pizza where we also celebrated the member's who had birthdays and "1/2" birthdays this month.---Roger Gass.


The March 2005 meeting of the Twin Cities Chapter of the American Meteorological Society was held on March 22, 2005, in conjunction with the 9th Annual Northern Plains Convective Workshop at St. Thomas University. After a brief business meeting where results of local science fairs were discussed, we heard from featured speaker Jon Davies about a practical and ingredients-based approach to tornado forecasting.

Jon classified three different types of conditions from which strong (F2 or greater damage) tornadoes: Supercell, nonsupercell, and cold-core lows. Each type of situation has its own set of parameters. For supercell tornadoes, CAPE, storm relative helicity, deep layer wind shear, and low lifting condensation levels (LCL) are key parameters. Nonsupercell tornadoes which aren't associated with mesocyclones get their vorticity from the low levels. They need a well-defined boundary with pockets of enhanced vertical vorticity with a wind shift from south to west or northwest, CAPE, thunderstorm updrafts developing on the boundary in phase with and stretching vertical vorticity, and a steep low-level lapse rate with deep surface moisture. With cold-core low tornadoes, the normal supercell tornado parameters don't work. One needs a closed 500 mb low (-22C to -16C), a nearby surface low (within 200 miles of the upper low) with a cold front and warm front close by creating a triple point, a narrow moist axis (dewpoints warmer than 52F), clear air behind the cold front/dryline.

Jon then described a number of parameters which can be used to indicate the likelihood of different types of tornadoes. Some of these are available for viewing on the SPC web site. Jon cautioned forecasters from using the actual values of these fields as predictors and using values as "magic numbers" or "bulls-eyes"; instead, one should look at trends and relative values. Also, the coincidence of the maxima (or minima, as appropriate) are areas where one should focus attention for other parameters. The parameters might not outline the areas of the best storms, so they should not be used as an infallible forecast indicator, but as a guide.

After a short break, Jon led exercises with the group on using the principles in his talk to forecast the locations of tornadoes.

Our next meeting will be at 7pm on April 19, 2005, at the Twin Cities WFO in Chanhassen, MN. Rich Naistat will present an overview of the Advanced Warning Operations course he will facilitate at the WFO during 2004-05.---Chris Bovitz.
