Convective storm detection is the meteorological observation, and short-term prediction, of deep moist convection (DMC). DMC describes atmospheric conditions producing single or clusters of large vertical extension clouds ranging from cumulus congestus to cumulonimbus , the latter producing thunderstorms associated with lightning and thunder .
A mesoscale convective complex (MCC) is a unique kind of mesoscale convective system which is defined by characteristics observed in infrared satellite imagery. Their area of cold cloud tops exceeds 100,000 square kilometres (39,000 sq mi) with temperature less than or equal to −32 °C (−26 °F); and an area of cloud top of 50,000 square ...
A mesoscale convective complex (MCC) is a unique kind of mesoscale convective system which is defined by characteristics observed in infrared satellite imagery. They are long-lived, often form nocturnally, and commonly contain heavy rainfall , wind , hail , lightning , and possibly tornadoes .
The US National Weather Service developed an organized storm spotter training system starting in the 1970's. Meteorologist Alan Moller played a significant role in the development of the effort. He believed that storm spotters are a vital part of the Integrated Warning System since they provide "ground truth verification" for forecasters.
Monday, March 11, 7:00pm - Virtual Spotter Training from NWS Paducah (Registration Required) Tuesday, March 12, 6:00pm - Skywarn Spotter Training - Madison County
As of May 21, the Storm Prediction Center (SPC) has tallied 317 storm spotter reports in the United States of hail larger than 2 inches in diameter (a golf ball is 1.75 inches).If that sounds like ...
At the small end, it includes storm-scale phenomena (the size of an individual thunderstorm [1]). Examples of mesoscale weather systems are sea breezes , squall lines , and mesoscale convective complexes .
The Storm Prediction Center began asking for public comment on proposed categorical additions to the Day 1-3 Convective Outlooks on April 21, 2014, for a two-month period. [24] The Storm Prediction Center broadened this system beginning on October 22, 2014 by adding two new risk categories to the three used originally.
