"More severe storms and heavy summer rains can be expected in Taiwan over the next 10 years, a team of researchers from National Taiwan University (NTU) said yesterday, citing a recent study they conducted in the South Pacific Ocean. The study found a correlation between rising temperatures in the vast ocean and increasing summer rainfall in Taiwan, said one of the team leaders, Shen Chuan-chou (沈川洲), a professor at NTU’s Department of Geosciences.
The Pacific Ocean is the largest in the world and plays an important role in climate change, he said.
In the study, the researchers analyzed strontium and calcium ratios in coral reef skeletons and used uranium-thorium dating methods on coral reef cores to reconstruct 350 years of sea surface temperature data in the Pacific dating from 1649 to 1999, Shen said. It was found that as temperatures in the South Pacific increased, it prevented cold air from settling, which weakened an atmospheric circulation system known as the Hadley cell in the southern hemisphere, Shen said. With a weakened Hadley cell, water vapor tends to shift north causing an increase in summer rainfall in Japan, South Korea, Taiwan and the Philippines, he said."
