MESOSCALE

Mesoscale Meteorology is the study of weather systems smaller than synoptic scale systems but larger than microscale and storm-scale cumulus systems. Horizontal dimensions generally range from around 5 miles to several hundred miles. Examples of mesoscale weather systems are sea breezes, squall lines, and mesoscale convective complexes.

Size scale referring to weather systems smaller than synoptic-scale systems but larger than storm-scale systems. Horizontal dimensions generally range from around 50 miles to several hundred miles. Squall lines , MCCs , and MCSs are examples of mesoscale weather systems.
