Evil sister

Hey /sci/, it's /tg/ here.

We got into a discussion about planets with supersonic winds. I've heard that Jupiter and Venus have what's referred to as "wind that exceeds the local speed of sound."

Can you guys explain what that means?

Everyone likes to understand things in terms that are familiar to them, so can someone explain what would happen if you tried to communicate via sound on one of these planets?

Let's assume we're superhumans and can withstand the environment. We stand some distance away from one another and yell really loudly into a super-duper megaphone that is really, really fucking loud.

"FUCK YOU!" I say to my friend.

Assuming we're standing in supersonic winds, what happens? Does the sound get carried along with the supersonic winds, essentially creating a new sound barrier? Is it for some reason slowed down by the winds? Let's assume that the wind is blowing away from Anon1 and towards Anon2. Both Anons yell "FUCK YOU!" What does each Anon hear?
