Honolulu Scholar Explains Record Rain

Posted on Wednesday, June 8, 2022

2022 ARCS Scholar T.J. Corrigan's research on a devastating 2018 supercell thunderstorm over Kaua‘i was featured in The Honolulu Star Advertiser. The storm shattered a 40-year U.S. record for most rainfall during a 24-hour period and caused extensive flooding. Corrigan and his advisor, Dr. Steven Businger of the University of Hawai‘i at Manoa's Storm Evolution and Energetics Research Group, described the storm dynamics, which included "rain bombs," in the journal Monthly Weather Review.

While Corrigan was away, Businger discussed a plus side of rain—explaining the physics of rainbows and why Hawai‘i is arguably the rainbow capital of the world. Watch the recording.
