MESOSCALE CONVECTIVE COMPLEX Meaning and
Definition
-
A mesoscale convective complex is a term used in meteorology to describe a large, organized cluster of thunderstorms that covers a relatively extensive area. It is characterized by a well-defined circulation pattern with a central area of low pressure, and is typically associated with a mature stage of convective storms.
These complexes usually develop during the late afternoon or evening hours, and often persist through the overnight hours as they move across the landscape. They can extend over hundreds of miles and can last for several hours. Mesoscale convective complexes commonly occur during the warm season in regions where there is ample moisture and atmospheric instability.
The primary characteristic of a mesoscale convective complex is its ability to generate strong and widespread rainfall over a large geographical area. These complexes often produce heavy rain, which can result in localized flooding, as well as damaging winds, hail, and frequent lightning. In some cases, tornadoes may also develop within or near the complex.
Mesoscale convective complexes are important for meteorologists to monitor due to their potential for causing significant severe weather and hazardous conditions. These complexes can have a significant impact on regional weather patterns, and their movement and evolution are often tracked using radar systems and satellite imagery.
