THERE IS NO EVIDENCE THEY FLEW INTO A CB
As I said on the last page: They flew right into the middle of one of the most intense storms seen in that region in the past 6 years. Numerous different platforms - not just those using temperature - detected heavy rain (near the upper limit of their capability), extreme convective activity (again, near the limits of their capabilities) and very cold clouds that exhibited large differences with height (indicative of an intense storm).
Based on those the Wx conditions the radar on AF447 should have had no problems picking up the storm. Radar systems similar to aircraft Wx radar (but space-based) detected the conditions with ease and as far as I remember from the report other aircraft changed course to avoid the same cloud formations - so they must've seen the problem.
