Global warming has a bigger effect on compact, fast-moving typhoons

A group from Nagoya University in Japan has found that larger, slower-moving typhoons are more likely to be resilient against global warming. However, compact, faster-moving storms are more likely to be sensitive. These findings suggest an improved method to project the strength of typhoons under global warming conditions. Their report was published in Geophysical Research Letters.

The larger, slower moving typhoons cause the sea temperature to drop largely, limiting the intensity of the storm. (credit: Reiko Matsushita)
