About 40% of the U.S. population<\/a> lives in a coastal area. In Hawaiʻi,<\/span> nearly everyone is vulnerable to the effects of tropical storms and hurricanes. Tropical cyclones, regionally known as hurricanes or typhoons, have been moving across ocean basins faster since 1982, according to a study led by University of Hawaiʻi<\/span> at Mānoa researchers, published in Environmental Research Letters<\/em><\/a>.<\/p>\n

The study, led by Sung-Hun Kim<\/strong>, a post-doctoral researcher in the ÌÇÐÄVlog¹Ù·½<\/abbr> Mānoa School of Ocean and Earth Science and Technology<\/a> (SOEST<\/abbr>) at the time of the work, also determined the North Atlantic region has experienced an increase in the frequency of hurricanes and that tropical cyclone activity has shifted toward the poles in the Pacific and Atlantic Oceans.<\/p>\n

The researchers, including Pao-Shin Chu<\/strong>, an atmospheric sciences<\/a> professor in SOEST<\/abbr>, focused on tropical cyclones since 1982, when modern, reliable satellite data became available. They assessed the frequency and locations of storms and trends in tropical cyclone movement speed\u2014how quickly a storm moves forward\u2014globally and regionally in each ocean basin.<\/p>\n

“For people in Hawaiʻi,<\/span> the threat of hurricanes is always there every year,” said Chu. “If hurricanes move faster, they would pose danger to coastal communities and emergency managers because they would have less time to prepare for evacuation and other measures.”<\/p>\n

The study suggests the reason for the observed changes is a combination of natural variations and human-induced climate change. The researchers continue to study the trends and connections between climate variability and tropical cyclone activity.<\/p>\n
