85th Annual Meeting Recorded Presentation HighlightsFor detailed science session and abstract information and all recorded presentations, please visit http://ams.confex.com/ams/Annual2005/techprogram/meeting_Annual2005.htm.
The climate of 2004 in historical perspective (Thursday, 8:30 a.m. Global Climate/Variability). An annual overview of regional and global climatic conditions and how they stack up to the historical record. A look back at the monthly, seasonal, and annual climate of 2004, as well as unusual events and extreme weather, across the U.S. and around the world. Arctic Change Detection Website (Monday, 11:30 a.m. Climate Variability/Change) Get a closer look at a comprehensive, near-real-time Arctic Change Detection Product has been developed by the US/NOAA Arctic Research Office to track physical and biological changes. The effort provides a continuous update to the Arctic Climate Impact Assessment (ACIA) Report, which is an expert evaluation of credible information from expert sources. Do windy conditions impact urban warming? (Monday, 4:15 p.m. Global Change/Variability) This study looks at the trends in temperature as a consequence of urban development or other local or instrumental influences. Forecasting global temperatures one year ahead (Monday, 4 p.m. Global Change/Variability) Global temperature is an important indicator of global climate change, and has been at near record levels in recent years. Predictions of global temperature for the year ahead are consequently of considerable interest to policy-makers. Can it be done? Assessing climate change (Tuesday, 1:30 p.m. Global Change/Variability) Leading climate scientist Susan Solomon will take a closer look at the key scientific results of the International Panel on Climate Change process and emerging questions that are among the topics to be assessed. She will also present a personal perspective on the pitfalls, pleasures, and challenges of scientific assessment. A multi-millennia perspective on drought and implications for the future (Tuesday, 2 p.m. Global Change/Variability) Dr. Kevin Trenberth will present the results and recommendations of a recent extensive workshop which looked at key climate questions as related to drought. What is the full range of past drought variability, as revealed by paleoclimate data? What role might droughts associated with abrupt climate change play? Are droughts likely to become more frequent, longer, or more extensive as we move into the future with global warming? Understanding temperature trends in the lower atmosphere (Tuesday, 4 p.m. Global Change/Variability) NOAA scientist Tom Karl will provide a closer look at understanding the complexities between different temperature data sets and a new product that address the accuracy and consistency of these temperature records and outline steps necessary to reconcile differences between individual data sets. A new system for measuring the carbon cycle (Tuesday, 4:30 p.m. Global Climate/Variability) Carbon cycle expert Dr. David Hofmann describes the atmospheric carbon profiling system that is being implemented in North America to provide the top-down data and the inverse modeling required to reduce the uncertainty in the North American carbon budget. The goal is to have an observing system of 36 total profiling sites in place by 2007. Modeling exercises suggest that this system would reduce the current uncertainty in the size of the North American carbon dioxide flux by a factor of two.
50 Years of Cloud Seeding in coastal southern California (Tuesday, 8:30 a.m. Weather Modification) The Santa Barbara precipitation enhancement project in coastal southern California is a landmark project in weather modification in the U.S. Learn more about the project’s success to date and future plans. What is the Snowy Precipitation Enhancement Research Program (Tuesday, 9:30 a.m. Weather Modification) The Snowy Precipitation Enhancement Research Program (SPERP) is a 6-year winter cloud seeding research program located in the Snowy Mountains of New South Wales, Australia. The purpose of this research program is to investigate the economic and environmental feasibility of augmenting snow precipitation for hydrogeneration and water supply requirements. The Weather Damage Modification Program (Wed. 1:30 p.m. Weather Modification) In 2002 Congress authorized funding of the Weather Damage Modification Program (WDMP). The funding has supported research in seven states: Colorado, New Mexico, Texas, Nevada, Utah, North Dakota, and Oklahoma, to increase water supplies at reduced cost and to reduce damage from drought and hail, by addressing current uncertainties and limitations of weather modification. What’s next?
How understanding the coastal zone is important to everyday life (Monday, 9:15 a.m. Coastal) As the U.S. Commission on Ocean Policy has noted, a profound lack of understanding pervades the U.S. population about the role oceans play in everyone's lives. Even among the millions who live along our coasts, people have difficulty connecting ocean and coastal issues with the things they care about the most. How important is the coastal zone really?
California and San Diego Area Related Topics Extreme heat and health impacts in California (Monday, 10 a.m. Heat) What is the health risk of extreme heat events in California? For an increasingly urbanized population, extreme heat waves create a significant risk of adverse health effects and heat-related mortality that is also greater than previously thought.
Lightning and its application to improving short-range forecasting (Tuesday, 11 a.m., Lightning) NASA lighting expert Steve Goodman explores how lightning measurements might best be used to improve short-term weather forecasting. Lightning and storm development (Tuesday, 11:30 a.m. Lightning) Sensors have show that the detection of lightning in storms over the oceans during the winter months is often an indicator of future storm development, intensification and precipitation intensity.
Developing a heat/health warning system (Monday, 9 a.m. Heat) Many National Weather Service office around the country are using new, more rigorous warning systems, designed to accurately identify those days most likely to cause health distress. Learn more about these systems are saving lives. How do communities respond? Intervention activities to lower heat-related mortality (Monday, 9:45 a.m., Heat) In the United States, extreme hot weather events account for more deaths per year on average than hurricanes, lightning, tornadoes, floods, and earthquakes combined. The trends toward a growing older population and a warmer climate both will act to increase the risk posed by extreme heat events in the future. On the other hand, adaptive measures and technologies seem to be lessening the adverse impacts associated with these events. The U.S. Environmental Protection Agency, NOAA's National Weather Service, and the Centers for Disease Control & Prevention are beginning work with local meteorologists, public health officials, and emergency management specialists to produce an excessive heat response guidebook. The guide will provide interested local officials with information on developing and implementing effective excessive heat notification and response programs, along with innovative heat island reduction measures designed to cool the community. Get a closer look at the guidebook. Extreme heat and health impacts in California (Monday, 10 a.m. Heat) What is the health risk of extreme heat events in Creating a nationwide surface transportation weather observing and forecasting system (Tuesday, 9 a.m. IIPS) For years, State Departments of Transportation have invested in thousands of environmental sensor stations along roadway rights-of-way, primarily in support of winter maintenance activities. Unfortunately these sensors are unique to each state and system and do not work well together. Setting up a national system with standard sensors could lead to a dramatic increase in the number of observations at the surface and ultimately safer roads.
Using a portable light detection systems to detect remote wildland fires and smoke (Monday, 9:45 a.m. Lidar) For safety, meteorologists on the front line of wildland fires are using an eye-safe, portable lidar for remote wildland fire and smoke detection. This infrared, eye-safe wavelength system can remotely detect smoke, flame fronts, and even air flow – all critical signs in monitoring wildland fires. Lidar observation of jet engine exhaust for air quality (Monday, 5 p.m., Lidar) Jet aircraft emit both gaseous and particulate pollutants. These emissions during taxi and takeoff operations are major considerations for an air quality analysis in the vicinity of airports. This paper discusses two ways by which lidar can increase the experimental understanding of how such emissions might affect air quality.
