Angusm  asked the Naked Scientists:
   
Hi Chris,

Have the scientists not yet evaluated the effect of cloud seeding and whether enough rain can be created to dampen down the ash?

Or is there a problem doing that? What do you think?

Can you raise it on Redi Direko show on 702 SAfrica. Fridays.

Gus in Florida,
Roodepoort South Africa.

What do you think?

[Bass]

You need two things
1. Clouds
2. For those clouds to be sufficiently high enough to cover the ash and have enough moisture content to seed- high ice clouds wouldn't work well.

And the disruptive ash is at 35,0000 feet. Most clouds never get that high. Only the most sever inland thunder storms.
