In many parts of the world, heavy, frequent rainstorms are catastrophic events that cause mudslides, flooding and loss of life.
An international team of experts led by Colorado State University atmospheric scientists are spending this summer getting to the bottom of how and why the most violent rainstorms in the world occur. By identifying the key physical processes and environmental ingredients that cause high-intensity, long-duration rain events, their goal is to improve models for forecasters and eventually save lives.
The team is led by Michael Bell and Kristen Rasmussen, both faculty members in the Department of Atmospheric Science, and includes collaborators from the National Center for Atmospheric Research in Boulder, seven other U.S. academic institutions and several international partners in Taiwan, Japan and Korea. The $6 million-plus field campaign is supported by the National Science Foundation and is called PRECIP, or Prediction of Rainfall Extremes Campaign in the Pacific. Data collection began in late May and will continue through August.
Alex DesRosiers received an Outstanding Oral Presentation Award from the 35th AMS Conference on Hurricanes and Tropical Meteorology for his talk, “Characterization of the Tropical Cyclone Vortex Height and Intensity Relationship in Observations.”
DesRosiers’ work used a large airborne radar dataset to quantify the strong relationship between vortex height and tropical cyclone intensity. He found differences in vortex height when accounting for current intensity were related to the rate at which the storm intensifies.
“The work motivates continued research to see if vortex height observations can be of use to tropical cyclone intensity forecasting,” he said.
Kevin Yang and Ting-Yu Cha were honored for outstanding student research in a ceremony May 6. Yang received the Herbert Riehl Memorial Award, and Cha received the Alumni Award.
The Alumni Award recognizes outstanding Ph.D. research by a senior student.
Professor Michael Bell, Cha’s adviser, nominated her for the paper, “Polygonal Eyewall Asymmetries During the Rapid Intensification of Hurricane Michael (2018).”
“This was outstanding work both in terms of observational analysis and theoretical analysis,” Bell said.
Ph.D. student Ting-Yu Cha has been selected for a National Center for Atmospheric Research Advanced Study Program Postdoctoral Fellowship. Following her graduation in the fall, Cha will move to Boulder in January 2023 to work with the NCAR Earth Observing Laboratory, where she will investigate the asymmetric mechanisms that impact tropical cyclone intensity and structure changes using observations and numerical models. Cha, who is advised by Professor Michael Bell, hopes this research ultimately will enable improved prediction and lead to better risk communication and weather warnings to the public.
“I am truly honored to be selected as an ASP postdoctoral fellow,” Cha said. “The program gives me the flexibility to conduct research I’m passionate about and an opportunity to grow independently. I am looking forward to collaborating with NCAR scientists and learning new science and skills!”
Ph.D. student Ting-Yu Cha received third place in the Peter B. Wagner Memorial Award for Women in Atmospheric Sciences competition. The paper she submitted, “Polygonal Eyewall Asymmetries During the Rapid Intensification of Hurricane Michael (2018)”, highlights the importance of coastal radar observations with high temporal resolution and the single Doppler radar wind retrieval algorithm, which can help to improve tropical cyclone intensity forecasts and investigate real-time TC intensity and structure changes.
This paper also was selected as an Editors’ Highlight by Eos in 2020. Cha’s co-authors on the paper were her adviser, Professor Michael Bell, Wen-Chau Lee and Alex DesRosiers.
Ph.D. candidate Chelsea Nam received the Best Student Oral Presentation Award from the 14th International Conference on Mesoscale Convective Systems and High-Impact Weather in East Asia (ICMCS-XIV). Nam’s presentation, “Bifurcation Points for Tropical Cyclone Genesis in Sheared and Dry Environments,” was co-authored by her adviser, Professor Michael Bell, and Dandan Tao, a former research scientist in the Bell group.
Naufal Razin and Jon Martinez received awards at the 34th AMS Conference on Hurricanes and Tropical Meteorology on May 14. Razin won the first-place student poster award for “Tropical Cyclone Precipitation, Infrared, Microwave, and Environmental Dataset (TC PRIMED).” Martinez won the second-place student poster award for “Characterizing the Nature and Evolution of Asymmetric Structures in Idealized Simulations of Rapidly Intensifying Tropical Cyclones,” as well as the conference’s top award, the Max Eaton Student Prize for “On the Contributions of Incipient Vortex Circulation and Environmental Moisture to Tropical Cyclone Expansion.”
Colorado State University hurricane researchers are predicting an above-average Atlantic hurricane season in 2021, citing the likely absence of El Niño as a primary factor. Tropical Atlantic sea surface temperatures are near their long-term averages, while subtropical Atlantic sea surface temperatures are much warmer than their long-term average values. The warmer subtropical Atlantic also favors an active 2021 Atlantic hurricane season.

Ph.D. candidate Ting-Yu Cha, advised by Associate Professor Michael Bell, has received a two-year fellowship from the Taiwan Ministry of Education to study heavy rainfall in Taiwan.
Cha’s proposed project is “Examination of Dynamic and Thermodynamic processes of Heavy Precipitation over Taiwan with the upcoming PRECIP field campaign observations.” PRECIP, the Prediction of Rainfall Extremes Campaign in the Pacific, aims to improve understanding of the multi-scale processes important for generating extreme rainfall in the moisture-rich environment of Taiwan and the western North Pacific.
Colorado State University hurricane researchers have increased their forecast slightly and now call for a very active Atlantic hurricane season in 2020, citing the likely absence of El Niño as a primary factor. Sea surface temperatures averaged across portions of the tropical Atlantic are somewhat above normal, while the subtropical Atlantic is much warmer than average. This type of sea surface temperature configuration is also considered favorable for an active 2020 Atlantic hurricane season.

Colorado State University hurricane researchers are predicting an above-average Atlantic hurricane season in 2020, citing the relatively high likelihood that El Niño conditions will not be present as a primary factor. Tropical and subtropical Atlantic sea surface temperatures are currently warmer than their long-term average values and are consequently also considered a factor favoring an active 2020 Atlantic hurricane season.
