Planetary scale
on a global size, think Rossby waves
synoptic scale
about the size of a country
Mesoscale
size of weather features, like thunderstorms or land-sea winds
Microscale
very small, like aeroplane turbulence
anticyclones
Clockwise flow. An anticyclone is an area of high pressure where air moves apart and sinks. Resulting in cloudless skys
Advection
The process of a fluid property moving with the flow.
basically wind
