Typhoons not linked to global warming...

More evidence that hurricanes are not linked with global warming...

A study of intense typhoons in the Pacific has failed to show a link with global warming, instead revealing that their number waxes and wanes naturally over the decades.

Even in the Atlantic, where these intense storms are called hurricanes, climate experts have not formed a consensus, with many - but by no means all - believing hurricanes have become stronger and longer-lasting over the past 30 years due to a rise in sea surface temperatures, possibly as a result of global warming.

Today, in the Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, a study of typhoons is published by Prof Johnny Chan, City University of Hong Kong.

A major conclusion of his study is that global warming apparently is not related to the frequency of intense typhoons.

Instead, such occurrences have a strong decadal variation caused by similar variations in the oceanographic and atmospheric conditions that govern the formation, intensification and movement of tropical cyclones.
