The ozone hole affects the rainfall in the tropical South Pacific
The ozone hole that opens each spring in the stratosphere over Antarctica has farther-reaching consequences than previously thought. A study of the climatology group now finds that even rainfall in the tropical South Pacific Islands is affected. During the period of the largest Antarctic ozone loss, from the 1960s to the 1990s, rainfall increased in French Polynesia in spring and early summer. The region lies near the tip of the so-called South Pacific Convergenze Zone, one of the most intense rain bands on Earth. Using climate models that simulate stratospheric ozone chemistry as well as observations covering the past 60 years, the researchers demonstrated that the ozone hole leads to a high-pressure ridge off New Zealand, from where a wave-like circulation pattern stretches across the South Pacific and affects the rain band.
