Mesoscale convective complexes:
A) occur along dry lines.
B) begin as air mass thunderstorms that form in the afternoon.
C) do not provide any benefit to agriculture.
D) tend to die out as soon as the sun goes down.

Question

Quizplus · Accepted Answer

Mesoscale convective complexes (MCCs) are large clusters of thunderstorms that can span over 100,000 square kilometers and persist for many hours. They often form in the late afternoon or evening when instability and moisture is greatest. Dry lines, which are boundaries between dry and moist air masses, can enhance the formation of thunderstorms but are not the primary cause of MCCs. MCCs can actually benefit agriculture by providing much-needed precipitation, although they can also cause flooding in some cases. MCCs can persist into the nighttime hours and can continue to produce thunderstorms, so choice D is incorrect.
