More frequent, more powerful Super Typhoons, with climate change

text-cat-questionIs not the push for nuclear reactors in East Asia (almost always located on coast) a dangerous trend, in view of increasing typhoons?

 

Super typhoons becoming more powerful and more frequent, new study finds, SMH,  Peter Hannam  6 Sept 16  The most destructive categories of tropical storms to strike the heavily populated regions of east Asia are becoming more intense and increasing as much as four-fold in frequency because of climate change, according to new research by US-based scientists.

Since the late 1970s, typhoons making land in a region stretching from Vietnam and the Philippines to Korea and Japan have become 12 per cent to 15 per cent more intense.

Those hitting south-east Asia with a category 4 or 5 strength have more than doubled in number, with the increase even more for China and Taiwan and regions north, the paper published in Nature Geoscience on Tuesday found.

The increase in sea-surface temperature is key to providing extra energy to tropical storms, with the outcome for the megacities of the region looking grimmer……..

“The intensification is strongest for typhoons that tend to make landfall because of the stronger warming of the coastal waters near east and south-east Asia,” said Wei Mei, a researcher in the department of marine sciences at the University of South Carolina and co-author of the paper.

Additional warming is expected to intensify the storms, particularly in some of east Asia’s main economic centres, Dr Mei said: “The typhoons striking mainland China, Taiwan, Japan, and Korea will intensify further because of the faster warming of waters of 20 degrees north.”…….

The north-west Pacific basin has both the largest data set of super typhoon-strength storms and the clearest trend towards intensification as the planet warms, Steve Turton, an adjunct professor at the Central Queensland University, said.

This year has also been an active one for the region………http://www.smh.com.au/environment/climate-change/super-typhoons-becoming-more-powerful-and-more-frequent-new-study-finds-20160905-gr8rch.html
