Human-Caused Warming will Cause More Slow-Moving Hurricanes, say Climate Models

Wednesday, Apr 22, 2020

Hurricanes moving slowly over an area can cause more damage than faster-moving storms, because the longer a storm lingers, the more time it has to pound an area with storm winds and drop huge volumes of rain, leading to flooding. The extraordinary damage caused by storms like Dorian (2019), Florence (2018) and Harvey (2017) prompted AOS Postdoctoral Research Associate Gan Zhang, a CIMES researcher, to wonder whether global climate change will make these slow-moving storms more common.

Zhang decided to tackle the question by using a large ensemble of climate simulations. He worked with an international team of researchers from GFDL and the Meteorological Research Institute in Tsukuba, Japan, among them former AOS Associate Research Scholar Hiroyuki Murakami (UCAR) and GFDL Research Meteorologist Tom Knutson. The results of this work appear in the April 22 issue of Science Advances.
