Just struck gold on Maestronet. Here's a post from one of the members there that includes a url for bowing terms. Should be fun to read through:

I have found a URL with a list of definitions for the various bowing techniques.

I think the one you are refering to is

SUL PONTICELLO = Bowing is down near the bridge and creates a glassy sounding tone.

My teacher has described this type of bowing to me in one of our lessons. The tone is more of a whistle than a screech so I could be wrong, but maybe one of the others is what you are looking for.
