Cloud Systems
(Temperature of cloud tops or land/sea surface if clouds are missing)

The scale is in Kelvin, dublicated in °C.

Airmasses

	Thick high-level clouds
	Thick mid-level clouds
	Jet stream, high Potential Vorticity (PV)
	Cold airmass
	Warm airmass – high tropopause
	Warm airmass – low tropopause
