Beijing Weather Modification Office

I wonder what the weather derivative boys and girls would make of this?
Beijing has a Weather Modification Office, the BWMO, responsible for "implementing weather modification tasks in Beijing area"

The WMO is enjoying considerable success right now clearing up Beijing's dust storms, through the use of stubby pencil-sized packages of silver iodide fired by rockets into rainclouds above the city.
You can read more about it here.
I wouldn't fancy a rainfall bet against these meteorologists!
