This is a list of meso-gamma mesoscale discussions, which are issued by the National Oceanic and Atmospheric Administration’s Storm Prediction Center during high-confidence and high-impact severe weather events.
Headquartered at the National Weather Center in Norman, Oklahoma, the Storm Prediction Center is tasked with forecasting the risk of severe thunderstorms and tornadoes in the contiguous United States. It issues convective outlooks, mesoscale discussions, and watches as a part of this process. Convective outlooks are issued for the following ...
The Weather Prediction Center ( WPC ), located in College Park, Maryland, is one of nine service centers under the umbrella of the National Centers for Environmental Prediction (NCEP), a part of the National Weather Service (NWS), which in turn is part of the National Oceanic and Atmospheric Administration (NOAA) of the U.S. Government.
Mesoscale meteorology. Mesoscale meteorology is the study of weather systems and processes at scales smaller than synoptic-scale systems but larger than microscale and storm-scale. Horizontal dimensions generally range from around 5 kilometres (3 mi) to several hundred kilometers. Examples of mesoscale weather systems are sea breezes, squall ...
Mesoscale convective system. A mesoscale convective system ( MCS) is a complex of thunderstorms that becomes organized on a scale larger than the individual thunderstorms but smaller than extratropical cyclones, and normally persists for several hours or more. A mesoscale convective system's overall cloud and precipitation pattern may be round ...
On the evening of March 24, 2023, a large and destructive tornado struck the communities of Rolling Fork and Silver City, Mississippi, killing 17 people and injuring at least 165 others. [1] [2] [3] The tornado was the strongest and deadliest of a widespread tornado outbreak in the Southern United States between March 24–27, 2023.
The Cooperative Institute for Severe and High-Impact Weather Research and Operations (CIWRO) is one of 16 NOAA Cooperative Institutes (CIs), hosted at the University of Oklahoma. [1] Before Oct. 1, 2021, it was known as the Cooperative Institute for Mesoscale Meteorological Studies (CIMMS). [2] The CIMMS/CIWRO, a research organization created ...
The Lab also works closely with the Storm Prediction Center (SPC) and the National Weather Service Norman Forecast Office, which are co-located at the National Weather Center (NWC) in Norman, Oklahoma. The NWC houses a combination of University of Oklahoma, NOAA and state organizations that work in collaboration.
