Macroscale - A large scale event usually measured in 10,000's of kilometers and weeks of time; a planetary scale event; e.g. long waves in the jet stream.
macroscalePertains to meteorological phenomena, such as wind circulations or cloud patterns, that are greater than 200 kilometers in horizontal extent.melting layerThe layer below the 0°C isotherm where snowflakes melt and turn into raindrops.
The air is drawn in to the intertropical convergence zone by the action of the Hadley cell, a macroscale atmospheric feature which is part of the Earth's heat and moisture distribution system.
RETROGRESSION In meteorology, it is the movement of a weather system in a direction opposite to the direction of the basic flow in which it is embedded. Often used in reference to a long wave trough or other macroscale feature.
Stratiform Rain: Horizontally widespread rain, uniform in character, typically associated with macroscale fronts and pressure systems.
The mesoscale covers the range from a few kilometres to a few tens of kilometres. Scales smaller than the mesoscale are considered microscale processes and those larger, macroscale processes. Often loosely called the local scale.
LARGE SCALE - A scaling term for large scaled weather systems. Often depicts a size of 100 miles or more. Sometimes called MACROSCALE.
