Weather forecasters rely on an incredibly large amount of information when they make forecasts and issue warnings. A new system, activated by NOAA\u2019s National Weather Service last week, quickly harnesses the tremendous amount of weather data from multiple sources, intelligently integrates the information, and provides a detailed picture of the current weather.<\/p>\n
The Multiple Radar Multiple Sensor (MRMS) system combines data streams from multiple radars, satellites, surface observations, upper air observations, lightning reports, rain gauges and numerical weather prediction models to produce a suite of decision-support products every two minutes. Because it provides better depictions of high-impact weather events such as heavy rain, snow, hail, tornadoes, and other threats, forecasters can quickly diagnose severe weather and issue more accurate and earlier forecasts and warnings.<\/p>\n
\u201cMRMS uses a holistic approach to merging multiple data sources, allowing forecasters to better analyze data and potentially make better predictions,\u201d said Ken Howard, a research meteorologist at NOAA\u2019s National Severe Storms Laboratory who helped design MRMS. \u201cIt was developed in collaboration with NOAA\u2019s National Weather Service hydrologists and forecasters who tested experimental versions and provided valuable input and feedback.\u201d<\/p>\n
Researchers at NOAA\u2019s National Severe Storms Laboratory designed the MRMS system to improve decision making within NOAA and other agencies – marking another NOAA research to operations success. Implementation of the system into NWS operations was funded in part by the Disaster Relief Appropriations Act of 2013.<\/p>\n
MRMS will improve the ability of forecasters to issue public warnings and advisories for severe weather such as tornadoes, hail and flash floods, and will help improve forecasts for safety of air traffic.<\/p>\n
NSSL\u2019s experimental version of the MRMS system has been available at various National Weather Service offices, but now that it is becoming operational, NOAA researchers plan to continue their collaboration with NOAA partners such as developers, trainers and forecasters to collect best practices and case studies. The system is designed so that new techniques and products can be added, increasing its capabilities.<\/p>\n
\u201cThe nationally consistent products available from the MRMS are another important step toward NOAA\u2019s goal of building a Weather Ready Nation by providing better analyses and forecasts to a wide range of decision makers,\u201d said Louis Uccellini, Ph.D., director of NOAA\u2019s National Weather Service. “This is another tool to help ensure communities are better prepared and more resilient in the face of high-impact weather events.”<\/p>\n
MRMS data are also an input into the newly operational High-Resolution Rapid Refresh weather model, which will improve the quality of forecasts and warnings for severe weather events.<\/p>\n
NOAA researchers developed the MRMS system in cooperation with The University of Oklahoma\u2019s Cooperative Institute for Mesoscale Meteorological Studies.<\/p>\n","protected":false},"excerpt":{"rendered":"
