Thunderstorm clusters that reach peak intensity in the middle of the night and cover thousands of square miles are called mesoscale convective complexes.
2.
A subset of these systems known as mesoscale convective complexes lead to up to 10 % of the annual rainfall across the Plains and Midwest.
3.
Along this boundary, mesoscale convective complexes ( MCCs ) or mesoscale convective systems ( MCSs ) tend to form and propagate eastward, giving a series of heavy downpours.
4.
Within a few hours, the thunderstorms, drawing energy from moisture-laden winds from the Gulf of Mexico, had organized themselves into a large cluster of storms called a mesoscale convective complex.
5.
Large thunderstorm areas known as mesoscale convective complexes move through the Plains, Midwest, and Great Lakes during the warm season, contributing up to 10 % of the annual precipitation to the region.
6.
There is less of a tendency for overestimating for very cold cloud tops using the H-E, and it does a much better job of estimating for large mesoscale convective complexes ( MCC's ).
7.
An especially long-lived and well-organized type of mesoscale convective system called a mesoscale convective complex produces on average 8 % to 18 % of the annual warm season rainfall across the Plains and Midwest.
8.
Rather large severe thunderstorms covering wide areas are well known in the Great Lakes during mid-summer; these Mesoscale convective complexs or MCCs can cause damage to wide swaths of forest and shatter glass in city buildings.
9.
Later that evening, the earlier activity formed into a mesoscale convective complex, and produced 11 tornadoes as the complex pushed into parts of southern Kansas, southwestern Missouri and northeastern Oklahoma; many of which developed without advance warning.
10.
A mesoscale convective system's overall cloud and precipitation pattern may be round or linear in shape, and include weather systems such as tropical cyclones, squall lines, lake-effect snow events, polar lows, and Mesoscale Convective Complexes ( MCCs ), and they generally form near weather fronts.
