Just a reminder that high alt windshear and jet streams are not usually found in the ITCZ region. .... CBs are just plain dangerous in the ITCZ.
Agreed, hence why I tried to distance the "Jetstream" issue from this accident.
However, the same "effect" can be seen circumnavigating CB(s) - the CB itself influences the horizontal W/V (in both drn & speed) - now have multiple large CBs. It is fine for an SOP to say "avoid" by 20NM or whatever, but ATC, multiple CBs and experience can make this impractical or judged unnecessary.
