Climate change spells worse typhoons for China, Japan

PARIS: China, Taiwan, Japan and the Koreas will experience more violent typhoons under climate change, said researchers on Monday (Tuesday in Manila), presenting evidence for a recent rise in storm intensity caused by ocean warming. Scientists have struggled to identify changes in the intensity and frequency of typhoons over the northwest Pacific ocean — never mind trying to pinpoint a role for global warming. Contradictory trends emerge from records such as the Joint Typhoon Warming Center and the Japan Meteorological Agency — the two most widely-used data sets in typhoon research, according to the US-based study authors Wei Mei and Shang-Ping Xie. They have now corrected the available data for differences in methodology and discovered a single, clear trend. “Over the past 37 years, typhoons that strike east and southeast Asia have intensified by 12-15 percent,” they wrote in the journal Nature Geoscience.
