What is Mesoscale Meteorology?

Posted by on Wednesday, September 21, 2016

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 kilometers to several hundred kilometers.

Mesoscale Meteorology is divided into these subclasses:

  • Meso-alpha 200–2000 km scale of phenomena like fronts, squall lines, mesoscale convective systems (MCS), tropical cyclones at the edge of synoptic scale.

  • Meso-beta 20–200 km scale of phenomena like sea breezes, lake effect snow storms.

  • Meso-gamma 2–20 km scale of phenomena like thunderstorm convection, complex terrain flows.
