The focal theme of this year's EMS Annual Meeting is High Impact Weather: Working in Partnership to Reduce Risk. By focusing talks and sessions around this theme, organizers hope to emphasize the partnership dimension of meteorological services.
This year's theme for the annual forum held in Washington, DC is “the value and sustainability of the weather, water and climate enterprise.” Recent research indicates that the annual economic impact of weather events is as much as $485 billion in the United States.
Global climate is changing, and this is apparent across the U.S. in a wide range of observations. Rising temperatures, changes in precipitation and extreme events and their causes and impacts on society and the environment are chronicled in the 2013 National Climate Assessment. A team of over 240 experts compiled the report, which is open for public comment through April 12, 2013.
Climate normals are the average values of meteorological parameters -- such as temperature, precipitation, frost/freeze data, and snowfall data -- over 30-year spans. The climate normals data help describe typical climate conditions for a given place and time of year, and are used as a baseline to which current conditions can be compared.
NOAA's Climate Prediction Center provides daily forecast maps of Ultraviolet (UV) Index for 58 U.S. cities, colored coded to their anticipated level of exposure. According to the World Health Organization, prolonged exposure to the sun's UV radiation may result in acute and chronic health effects on our skin, eyes, and immune system.
Drought is one of the most costly natural disasters affecting the United States. The National Integrated Drought Information System (NIDIS) helps the nation and North America understand and proactively prepare for drought by providing data and information about the extent and potential impacts of drought and associated risks. The system provides a variety of decision support tools to help people prepare for and mitigate the effects of drought.
This activity engages learners in examining data pertaining to the disappearing glaciers in Glacier National Park. After calculating percentage change of the number of glaciers from 1850 (150) to 1968 (50) and 2009 (26), students move on to the main glacier-monitoring content of the module--area vs. time data for the Grinnell Glacier, one of 26 glaciers that remain in the park.
This NOAA visualization video on YouTube shows the seasonal variations in sea surface temperatures and ice cover for the 22 years prior to 2007 based on data collected by NOAA polar-orbiting satellites (POES). El NiÃo and La NiÃa are easily identified, as are the trends in decreasing polar sea ice.
This Flash-based simulation explores the relationship between carbon emissions and atmospheric carbon dioxide using two main displays: (1) graphs that show the level of human-generated CO2 emissions, CO2 removals, and the level of CO2 in the atmosphere, and (2) a bathtub animation that shows the same information as the graphs. The bathtub simulation illustrates the challenges of reducing greenhouse gas concentrations in the atmosphere.
