Radioactive cloud follow up in Asia: pilot wind report.
It seems radioactivity reached Tokyo yesterday because of the wind.
For the ones flying out of Japan, Korea, China... Maybe we could share our observation about winds in Japan and around Japan at different altitude and time to have an idea where could be the dangerous areas now and in the few coming days.
I start:
Flew very early out of Beijing last night and came back very early this morning (Beijing time).
Wind:
1-surface: 340 degres, 10 knots.
2-Up to 10 000 feet: 300 degres 35 knots.
3-10 000 to 35 000 feet flying southbound: from 300 degres changing to 260 degres at higher altitude, from 35 knots increasing to 165 at higher altitude.
