Mesoscale
From Freepedia
The term mesoscale is a 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, Mesoscale Convective Complexes, and Mesoscale Convective Systems are examples of mesoscale weather systems.
Mesoscale can be further divided to subclasses
- Meso-gamma 2-20 km, deals with phenomena like Thundestrorm convection, complex terrain flows (at the edge to micro-scale, also known as storm-scale)
- Meso-beta 20-200 km deals with phenomena like sea breezes
- Meso-alpha 200-2000 km fronts, deals with phenomena like low pressure systems, at the edge of synoptic scale
