Some other resources (outside Wikipedia):
- Kean University:
- Documented by the NOAA in US (but I don't find the complete reference)
- These symbols seem to be supported by an "international standard", but I
don't know which one exactly.
- Documented with other symbols (rain, ice, snow, thunder...) in Canada for
flight planning
