Ozone Layer Dynamics
I am trying to find out if there is a partial hole in the Ozone Layer
the South American Region. Would you happen to know if there is, and
geographical area is it situated over.
The very southern tip of South America is sometimes
affected by some decrease in ozone from the dilution
over Antarctica, however, it is quite small. The
greater problem occurs during the breakup of the
ozone "hole" in late Spring. Blobs of ozone depleted
air float over much of southern South America, posing
a significant skin cancer hazard to those who live
Take a look at more information and lots of neat
ozone "hole" graphics at www.atm.ch.cam.ac.uk/tour/index.html
