As summer storms roll though your region, have you wondered who is behind the science of a weather warning?
In west Texas and portions of southeast New Mexico, College of LAS alumnus Devin Chehak (BS, ’18, atmospheric sciences...
Atmospheric scientist Kelvin Droegemeier to join University of Illinois faculty Accomplished alumnus who previously led White House Office of Science and Technology Policy also will advise the chancellor and support U of I System Kelvin Droegemeier, a research meteorologist who previously held several national science and policy leadership roles, is joining the faculty of the Department of...
MARCH 10, 2023 BY ISABELLA ZARATE | LAS “Exhausting, hard work, and muddy,” are the words atmospheric sciences graduate student Leanne Blind-Doskocil uses to describe the Propagation, Evolution, and Rotation in Linear Storms (PERiLS) campaign. “But so worthwhile,” Blind-Doskocil added, recently. Imagine one day you are chasing a tornado, and the next...
DEC 6, 2022 BY LOIS YOKSOULIAN | PHYSICAL SCIENCES EDITOR An almost limitless supply of fresh water exists in the form of water vapor above Earth’s oceans, yet remains untapped, researchers said. A new study from the University of Illinois Urbana-Champaign is the first to suggest an investment in new infrastructure capable of harvesting oceanic water...
CHAMPAIGN, Ill. — Prof. Atul Jain has once again been recognized as one of the world’s most influential scientists. See the story here to learn more about the 2022 Clarivate Analytics Highly Cited Researchers list.
NATIONAL ACADEMY OF SCIENCES, WASHINGTON — A global clearinghouse for greenhouse gas emissions information should be created to support decision-makers working to address climate change, says a new report from the National Academies of Sciences, Engineering, and Medicine. Such a clearinghouse could facilitate new ways of estimating emissions and transition research findings to operations more...
Prof. Deanna Hence has been named a Lincoln Excellence for Assistant Professor (LEAP) Scholar within the College of Liberal Arts & Sciences. This distinguished award recognize’s Prof. Hence’s significant achievements and outstanding future potential as a faculty member at Illinois. A full description of the awards program and other awardees can be found...
(Argonne National Laboratory and College of LAS, 9/8/2022) The U.S. Department of Energy (DOE) has awarded DOE’s Argonne National Laboratory and a team of academic and community leaders—including the University of Illinois Urbana-Champaign—$25 million over five years to advance urban climate science by studying climate change effects at local and regional scales. The results of this new...- During cloud processes, aerosol particles undergo physical and chemical changes. In this work by Dr. Yu Yao, and Professor Nicole Riemer, a particle-resolved model was used to quantify the changes in aerosol mixing states. They linked the particle-resolved aerosol model PartMC-MOSAIC with the cloud chemistry module CAPRAM 2.4 and designed cloud simulations that simulated several cloud cycles to...
Balloon launches are typically the stuff of birthday parties and photo opps unless you’re an atmospheric scientist trying to gather storm data in tandem with NASA research planes navigating their way through giant blizzards. Then they require a bit of creativity and determination. That was a job requirement in late January for graduate students Andrew Janiszeski (MS, ’20; ...
This March and April, University of Illinois Atmospheric Sciences faculty will lead a multi-institutional team of researchers to study tornadoes and other severe weather in the southeast US. The project is called PERiLS, which stands for Propagation Evolution and Rotation in Linear Storms, and will be based in Memphis, Tennessee, near an understudied...
In a study recently published in the journal Atmosphere, ATMS graduate student Lina Rivelli-Zea leveraged disdrometer data collection in the Americas to compare the drop-size distributions and parameters across field campaigns for the first time. Prof. Steve Nesbitt and graduate student Alfonso Ladino Rincon contributed to this study. The data were collected at two sites in the...
The Gibson City flood occurred on August 12, 2021, in Gibson City, Illinois. During this event, around 10 inches of rain fell in less than 10 hours. There were numerous water rescues conducted during the event and after it ended. During the flooding event, all the roads were impassable in Gibson City at one point. The evolution of this flooding event can be visualized through a “story map” (...- SEP 13, 2021 10:00 AM BY LOIS YOKSOULIAN | PHYSICAL SCIENCES EDITOR A new, location-specific agricultural greenhouse gas emission study is the first to account for net carbon dioxide, methane and nitrous oxide emissions from all subsectors related to food production and consumption. The work, led by University of Illinois Urbana-Champaign atmospheric sciences...
The study was conducted by Professor Sonia Lasher-Trapp, current graduate student Enoch Jo, and recent alumni Luke Allen and Bryan Engelsen. It identifies and quantifies various mechanisms of entrainment, and their diluting effects, in the developing and mature stages of a simulated supercell thunderstorm. The two stages, differentiated by the lack or presence of a rotating updraft, are shown to...
