( 1994) The Canadian operational procedure for forecasting total ozone and UV radiation. A replacement for the Dobson spectrophotometer? Pure Appl. On the relation between ozone and potential vorticity. Copyright © 2002 Royal Meteorological Society. It allows the inhabitants of the Magallanes region to be alerted to potentially high incidences of UV-B radiation during the Austral spring. The method is based on the prediction of the 100 mb-temperature from ECMWF (European Centre for Medium-Range Weather Forecasts), which is well correlated with total column ozone levels. In this work we apply and further develop a pilot study carried out in 1995 which looks at the simple operational method of forecasting ozone levels some 42 hours in advance. Consequently, there is great concern among the inhabitants of this region regarding the possible effects of long-term exposure to UV-B. Ozone denatures DNA, and prolonged exposure may cause skin carcinoma and cataracts. Owing to the decrease of stratospheric ozone during the southern spring (starting in September), the city of Punta Arenas (53.1 °S, 70.9 °W) and its surroundings are exposed to a high incidence of ultra-violet-B (UV-B) radiation during this period.
