Williamson). This image was chosen for the cover because the NEXRAD program so well epitomizes the benefit that coordination of Federal meteorological services and supporting research has brought to the Nation. NEXRAD was a tri-agency program and the cornerstone of National Weather Service modernization in the 1990s, providing significant improvements in severe weather warnings. A 2005 study (Simmons and Sutter) determined the NEXRAD system reduced expected fatalities by 45 percent and injuries by 40 percent—estimated at 79 lives saved and 1,050 fewer injuries per year. The Federal Role in Meteorological Services and Supporting Research A Half-Century of Multi-Agency Collaboration Federal Coordinator for Meteorological Services and Supporting Research 8455 Colesville Road, Suite 1500 Silver Spring, MD 20910 (301) 427-2002 www.ofcm.gov FCM-I7-2013 Author: Dr. Robert Katt Washington, D.C. 2nd Author: Michael Babcock November 2013 PREFACE The aims and achievements of the Office of the Federal Coordinator for Meteorological Services and Supporting Research (OFCM) over the half-century of its existence are aptly captured in its mission statement: To ensure the effective use of Federal meteorological resources by leading the systematic coordination of operational weather requirements, services, and supporting research, among the 15 stakeholder Federal agencies and offices. From the time the OFCM was created in 1964 and Dr. Robert M. White was appointed the first Federal Coordinator, a coordinating infrastructure of interagency committees, program councils, and working groups has provided policy guidance, technical and project-level expertise, and project oversight for the activities undertaken, sponsored, or overseen by the OFCM. This infrastructure has evolved to meet the challenges of keeping this diverse set of programs and constituent interests working together as a reasonably coherent and cost-effective enterprise. Viewed as an enterprise— for purposes of this report, we call it the Federal meteorological enterprise—it has returned excellent value on the taxpayers’ investment. This retrospective recounts the panoply of meteorological services delivered to end users and the supporting research and partnerships that have made those services possible. For example, we recount the history of OFCM involvement in the Nation’s weather radar capability, from the first Federal Coordinator’s support for research, development, and testing of emerging Doppler radar technology through the substantial role played by the OFCM infrastructure in initiating and implementing today’s NEXRAD network of weather radars. The program was the first successful acquisition program funded and co-managed by three Federal departments (Commerce, Defense, and Transportation). The OFCM role in improving weather radar continues today as we coordinate the multi-agency work on a new generation of radar—multifunction phased array radar, or MPAR—which can support national aircraft surveillance needs for civil aviation and homeland security, as well as concurrent multiple atmospheric observing functions. Another success story that traces back to the OFCM’s first days is the improvement in hurricane warnings and forecasts through better observing instruments for Hurricane Hunter aircraft and through coordination of research on the computer-based models that use the data from those instruments and others to analyze and predict the evolution of tropical cyclones. From the beginning, the OFCM has also led efforts to improve both the warning system for and the post- storm response to other severe weather events such as tornadoes, winter storms, and floods. Computer-based modeling is essential for predicting the weather and for warning both the general public and specialized communities of users (e.g., transportation, agriculture, and military) in time to make decisions that save lives and reduce the costs of adverse weather. The OFCM has aided the rapid advance of the large-scale numerical weather prediction (NWP) models and has played a vital role in assessing and improving the finer-scale models used to simulate the dispersion of airborne toxic materials, whether released accidentally or deliberately. The OFCM role with these atmospheric transport and diffusion (ATD) models began in the 1960s and 1970s, when the principal concern was air pollution, and continued through the Three Mile Island nuclear power plant incident in March 1979 and the events of September 11, 2001. As the uses for ATD modeling The Federal Role in Meteorological Services and Supporting Research have evolved, the OFCM has formed multi-agency groups to assess the models and plan coordinated research and development programs to meet these evolving needs. The principal sources of information for this retrospective are OFCM-published reports, plans, and handbooks, along with interagency correspondence and OFCM internal documents. Foremost among these are the annual Federal plans for meteorological services and supporting research, a statutory requirement compiled each year by the OFCM with input from the Federal departments, agencies, and offices that participate in the coordinating infrastructure. In addition, we have drawn on other government reports and documents, the technical literature, and sources available on the Internet. These source documents are cited where appropriate in the text and listed in the References section at the end of the report. As the tenth individual to hold the title of Federal Coordinator, I am both pleased and proud to report that the Federal meteorological enterprise is poised to continue delivering ever greater value in meeting the Nation’s changing needs for meteorological and climatological services and products. For me, this retrospective is one way to express both the Nation’s gratitude and my personal thanks to all the individuals who, during the past half-century, have participated in the OFCM’s coordinating infrastructure. They have identified users’ needs, assessed existing services, and planned and implemented the improvements from which we all benefit. As I look back over my 12 years with the NEXRAD program and 16 years as Federal Coordinator, I want to thank all those who prepared and supported me. Among them are Professor Allen H. Weber, my advisor in the meteorology program at North Carolina State University; Robert M. White, who gave both vision and leadership to the new National Oceanic and Atmospheric Administration as its founding Administrator, while also creating and directing the coordinating infrastructure that makes OFCM unique; Richard Hallgren, Director of the National Weather Service whose foresight and vision guided the NEXRAD program and the modernization of the National Weather Service; Elbert W. “Joe” Friday, Director of the National Weather Service who made the Modernization and Restructuring a reality; D. James Baker, who, as NOAA Administrator and FCMSSR chair, supported the vision and ambitious plans of a new Federal Coordinator; VADM Conrad Lautenbacher, who, as NOAA Administrator, supported so many service improvements; Paul D. Try, professional colleague and friend since the early NEXRAD days; and Robert Dumont, who has been my strong right hand and served as OFCM’s first Chief Scientist. Two individuals who have passed on but for whose support I remain ever thankful are Col. William S. Barney, with whom I worked while he was Federal Coordinator, and Arthur L. Hansen, who, as the first director of the Joint System Program Office, brought me into the NEXRAD program as deputy director and guided it through its rocky first years. Lastly, I want to thank the men and women who served in the NEXRAD Joint System Program Office—we

  • Fire W Eather
    Fire Weather Fire Weather Fire weather depends on a combination of wildland fuels and surface weather conditions. Dead and live fuels are assessed weekly from a satellite that determines the greenness of the landscape. Surface weather conditions are monitored every 5-minutes from the Oklahoma Mesonet. This fire weather help page highlights the surface weather ingredients to monitor before wildfires and also includes several products to monitor once wildfires are underway. Fire Weather Ingredients: WRAP While the presence of wildland fuels is one necessary component for wildfires, weather conditions ultimately dictate whether or not a day is primed for wildfires to occur. There are four key fire weather ingredients and they include: high Winds, low Relative humidity, high Air temperature, and no/minimal recent Precipitation (WRAP). High Winds are the second most critical weather ingredient for wildfires. In general, winds of 20 mph or greater 20+ mph winds increase spot fires and make for most of the containment considerably more difficult. state Low Relative humidity is the most 30-40+ critical weather ingredient for wildfires mph winds and is most common in the afternoon when the air temperature is at its warmest. When relative humidity is at or below 20% extreme fire behavior can result and spot fires become freQuent. Watch out for areas of 20% or below relative humidity and 20 mph or higher winds à 20/20 rule! Extremely low relative humidity Warm Air temperatures are another values key weather ingredient for wildfires as warming can lower the relative humidity, reduce moisture for smaller dead fuels, and bring fuels closer to their ignition point.

  • Weather Charts Natural History Museum of Utah – Nature Unleashed Stefan Brems
    Weather Charts Natural History Museum of Utah – Nature Unleashed Stefan Brems Across the world, many different charts of different formats are used by different governments. These charts can be anything from a simple prognostic chart, used to convey weather forecasts in a simple to read visual manner to the much more complex Wind and Temperature charts used by meteorologists and pilots to determine current and forecast weather conditions at high altitudes. When used properly these charts can be the key to accurately determining the weather conditions in the near future. This Write-Up will provide a brief introduction to several common types of charts. Prognostic Charts To the untrained eye, this chart looks like a strange piece of modern art that an angry mathematician scribbled numbers on. However, this chart is an extremely important resource when evaluating the movement of weather fronts and pressure areas. Fronts Depicted on the chart are weather front combined into four categories; Warm Fronts, Cold Fronts, Stationary Fronts and Occluded Fronts. Warm fronts are depicted by red line with red semi-circles covering one edge. The front movement is indicated by the direction the semi- circles are pointing. The front follows the Semi-Circles. Since the example above has the semi-circles on the top, the front would be indicated as moving up. Cold fronts are depicted as a blue line with blue triangles along one side. Like warm fronts, the direction in which the blue triangles are pointing dictates the direction of the cold front. Stationary fronts are frontal systems which have stalled and are no longer moving.

  • Weather Observations
    Operational Weather Analysis … www.wxonline.info Chapter 2 Weather Observations Weather observations are the basic ingredients of weather analysis. These observations define the current state of the atmosphere, serve as the basis for isoline patterns, and provide a means for determining the physical processes that occur in the atmosphere. A working knowledge of the observation process is an important part of weather analysis. Source-Based Observation Classification Weather parameters are determined directly by human observation, by instruments, or by a combination of both. Human-based Parameters : Traditionally the human eye has been the source of various weather parameters. For example, the amount of cloud that covers the sky, the type of precipitation, or horizontal visibility, has been based on human observation. Instrument-based Parameters : Numerous instruments have been developed over the years to sense a variety of weather parameters. Some of these instruments directly observe a particular weather parameter at the location of the instrument. The measurement of air temperature by a thermometer is an excellent example of a direct measurement. Other instruments observe data remotely. These instruments either passively sense radiation coming from a location or actively send radiation into an area and interpret the radiation returned to the instrument. Satellite data for visible and infrared imagery are examples of the former while weather radar is an example of the latter. Hybrid Parameters : Hybrid observations refer to weather parameters that are read by a human observer from an instrument. This approach to collecting weather data has been a big part of the weather observing process for many years. Proper sensing of atmospheric data requires proper siting of the sensors.

I am Dr. Louis Uccellini, Director of the National Oceanic and Atmospheric Administration’s (NOAA) National Weather Service (NWS). Within the NWS, NOAA’s National Hurricane Center (NHC) issues the official forecast for all Atlantic and eastern Pacific tropical cyclones (hurricanes, tropical storms and tropical depressions) and their precursors. It is my honor to testify before you today on the state of the United States hurricane forecasting capability; our efforts to improve our understanding and prediction of hurricane impacts from storm surge, heavy precipitation, and high winds; and what hurricane research focus areas are needed to improve prediction. I come before you today to report that hurricane forecasting accuracy has improved tremendously over the past two decades. The NHC track (storm location) forecast errors have decreased every decade since forecast accuracy records were established in the 1960’s, and NHC has set new records almost every year. For perspective, the average two-day Atlantic forecast location error was reduced from around 300 miles (approximately 260 nautical miles (n mi), see Fig. 1) in the 1960s to near 85 miles in the 2010s. The five-day forecast for storm location is now better than the day-and-a-half forecast was in the 1970s.

ATMOSPHERE: the envelope of gas that surrounds the surface of Earth; the air 2. WEATHER: the day to day changes in the atmosphere caused by shifts in temperature, air pressure, and humidity B. Meteorologists are scientists that study atmospheric sciences that include the following: 1. CLIMATOLOGY: the study of climate 2. ATMOSPHERIC CHEMISTRY: the study of chemicals in the air 3. ATMOSPHERIC PHYSICS: the study of how air behaves 4. HYRDOMETEOROLOGY: the study of how oceans interact with weather What is the atmosphere? A. The earth’s atmosphere is made of air. 1. Air is a mixture of matter that includes the following: a. 78% nitrogen gas b. 21% oxygen gas c. 0.04% carbon dioxide d. 0.96% other components like water vapor, dust, smoke, salt, methane, etc. 2. The atmosphere goes from the Earth’s surface to 700km up. 3. The atmosphere is divided into 4 main layers as one ascends. What is the atmosphere? a. TROPOSPHERE: contains most air, where most weather occurs, starts at sea level b. STRATOSPHERE: contains the ozone layer that holds back some UV radiation c. MESOSPHERE: slows and burns up meteoroids d. THERMOSPHERE: absorbs some energy from the sun What is the atmosphere? B. The concentration of air in the atmosphere increases the closer one gets to sea level. 1. The planet’s gravity pulls the atmosphere against the surface. 2. Air above pushes down on air below, causing a higher concentration in the troposphere.
