Jamin Rader chosen for DOE Computational Science Graduate Fellowship

Jamin Rader, who will join Elizabeth Barnes’ research group in Fall 2019, has been awarded a Department of Energy Computational Science Graduate Fellowship. DOE CSGF students receive full tuition and fees plus an annual stipend and academic allowance, renewable for up to four years, to apply to Ph.D. study in computational science or engineering. Less than 5 percent of applicants are chosen for the fellowship each year. Rader is the third ATS student to receive the DOE CSGF.

In addition to required courses in engineering, computer science and applied mathematics, DOE CSG fellows also must complete a three-month research practicum at one of 21 DOE sites. The practicum is intended to broaden the fellow’s experience outside their main thesis area, expose them to alternative methods or tools, and allow them to apply their skills to new problems in computational science.

“I am excited to use this [fellowship] to learn about machine learning and apply it to real-world problems related to, but separate from, my graduate studies – and then, of course, take this new skill and apply it to my studies at CSU,” Rader said.

Rader also received a one-year AMS Graduate Fellowship, which he had to decline in order to use the DOE fellowship.

Researchers working to prevent sexual harassment in scientific field settings

Scientists involved in a field campaign are away from their normal routines, offices and universities, including the support mechanisms available if sexual harassment or other inappropriate behaviors occur. Three Colorado State University researchers are examining the prevalence of sexual harassment in field-based research as part of a National Science Foundation-supported study.

The CSU team, which includes Emily Fischer, Kristen Rasmussen and Brittany Bloodhart, are also studying what psychological indicators might lead people to engage in – or intervene in – a harassment situation.

Part of their work is documenting how people respond when the issue of sexual harassment is openly discussed, and expectations for professional behavior are clearly set by team leadership. The goal: creating a policy and culture of collegiality and respect across field teams.

Their efforts are supported by nearly $300,000 from the National Science Foundation, awarded last year. The group used two recent CSU-led field campaigns as test cases and proving grounds for their project.

ATS researchers predict slightly below-average 2019 Atlantic hurricane season

Colorado State University hurricane researchers are predicting a slightly below-average Atlantic hurricane season in 2019, citing the relatively high likelihood of a weak El Niño as a primary factor.

Tropical Atlantic sea surface temperatures are currently slightly below their long-term average values and are consequently considered an inhibiting factor for 2019 Atlantic hurricane activity as well.

A weak El Niño has recently developed in the tropical Pacific. CSU anticipates that these weak El Niño conditions are likely to persist through the peak of the Atlantic hurricane season. El Niño tends to increase upper-level westerly winds across the Caribbean into the tropical Atlantic, tearing apart hurricanes as they try to form.

The tropical Atlantic is slightly cooler than normal right now. Colder-than-normal sea surface temperatures in the tropical Atlantic provide less fuel for tropical cyclone formation and intensification. They are also associated with a more stable atmosphere as well as drier air, both of which suppress organized thunderstorm activity necessary for hurricane development.

Inspiring young scientists: Atmos hosts 108 second-graders

There was a little extra excitement at Atmos on Friday. In addition to hosting five prospective graduate students, the department welcomed 108 second-graders from Altitude Elementary in Aurora. Young minds delighted in scientific discovery as the children rotated through several stations designed to teach them about precipitation, air pollution, and weather and climate.

Noah Newman, outreach coordinator for the Colorado Climate Center, discussed the water cycle with the students and reviewed what they knew about the atmosphere and how it protects us. They finished the station with a hands-on demonstration on how meteorologists measure three forms of precipitation: rain, hail and snow.

“All of the students did really well with answering the questions I posed to the classes, and they had many good questions and comments of their own,” Newman said. “Overall, it was a really fun day.”

Volunteers from Fort Collins Atmospheric Scientists, or FORTCAST, agreed that interacting with the young guests was fun. FORTCAST, a local chapter of the American Meteorological Society (AMS), is composed of mostly graduate students from the Department of Atmospheric Science. FORTCAST presents hands-on science at events like those held by CSU’s Little Shop of Physics and at their own event, Weatherfest, in the summer.

FORTCAST volunteers Sean Freeman, Jennie Bukowski and Kyle Chudler ran several interactive demonstrations that enthralled the schoolkids. Bukowski exhibited how clouds form in the atmosphere using water, a plastic bottle, a bike pump and smoke particles from a match, creating a cloud in a bottle for the students to examine up close. The children answered questions about the importance of clouds and rain and were thrilled to test the particle counter themselves.

Chudler showed the group how different colors either reflect or absorb heat, as evidenced by sheets of white and black paper under a heat lamp, so the students could feel the difference for themselves. He then displayed an image of the Earth and asked the students which areas would absorb heat and which would reflect it. They were able to extrapolate that receding ice means less reflective surface area as it becomes darker, heat-absorbing ocean, thereby warming the planet.

Chudler wowed them when he demonstrated air pressure by placing a heated can in ice water. The children’s eyes and mouths opened wide in awe as an aluminum soda can instantly crumpled when a vacuum formed inside.

Inquisitive kids flocked to Freeman’s table to check out a drone, its camera, and an iPad displaying the camera’s view in real time. Students waved and mugged for the camera as Freeman explained how he and other atmospheric scientists use drones for research, flying them into clouds and storms to collect data. The children were able to view footage taken by the drone in flight.

At another station, research scientist Katie Benedict taught the students about air pollution. They learned about particles in the atmosphere and how our noses and lungs filter those particles and protect our bodies. Benedict explained how increased aerosol in the atmosphere affects our visibility as light is scattered. The class compared filters and images from normal, hazy and smoky days that illustrated this phenomenon. Research scientists Arsineh Hecobian and Amy Sullivan also led demonstrations of smells from volatile organic compounds and the use of chromatography to separate a mixture of chemicals, in this case water-soluble marker colors.

The visit culminated in a weather balloon launch and drone flight. Despite the dreary weather, the youngsters exclaimed in enthusiasm as the balloon was released, and more than 100 little faces watched intently as it drifted higher into the clouds until it was out of sight.

For the grand finale, drone pilot Sean Freeman gave a much-anticipated flight demo of the drone’s maneuvering capability and snapped a few aerial shots of the enrapt second-graders. The kids cheered as the drone settled back onto the ground. After a unified “thank you” on their teachers’ cue, the second-graders boarded their buses, likely taking with them lessons they won’t soon forget.

Department Head Jeff Collett, who coordinated the visit, echoed the thoughts of one student who, just before departing, was overheard telling her teacher that it had been the “best day ever!”

Ben Toms earns 2 AMS outstanding presentation awards

Ph.D. student Ben Toms was chosen for two outstanding presentation awards at the American Meteorological Society’s annual meeting in January in Phoenix. Toms was honored for work completed during his M.S. studies, under the supervision of Professor Sue van den Heever. The Climate Variability and Change Program Committee selected Toms’ presentation, “Quantifying the Dependence of the Global Response to the Madden–Julian Oscillation on the Quasi-Biennial Oscillation,” for an Outstanding Student Presentation Award.

“We had a large number of very good student presentations this year, and we commend you on the work you have done,” committee members Rob Korty and Walt Robinson said in his notification letter.

Toms’ presentation was about quantifying the global “signature” of the Madden-Julian Oscillation within the upper troposphere and lower stratosphere.

“I have greatly enjoyed working with my collaborators on this project, (Professors) Libby Barnes, Eric Maloney, and Sue van den Heever,” Toms said. “We used a statistical technique to show that the global teleconnections of the Madden-Julian Oscillation depend on the phase of the Quasi-Biennial Oscillation, a tropical stratospheric oscillation. This suggests that the state of the tropical stratosphere is important for understanding the connections between the MJO and the extratropics.”

Toms also won an Outstanding Oral Presentation award at the 18th Conference on Artificial and Computational Intelligence and its Applications to the Environmental Sciences for his talk, “Climate Science, Deep Learning, and Pattern Discovery: The Madden−Julian Oscillation as a Test Case.”

For this project Toms worked with Karthik Kashinath and Prabhat of Lawrence Berkeley National Laboratory and Da Yang of the University of California, Davis to show that deep learning, a form of machine learning, can learn for itself the variables and spatial patterns important for characterizing multiscale geophysical phenomena such as the MJO.

Prof. Denning answers questions about weird winter weather phenomena

Editor’s note: Extreme cold weather can produce unusual phenomena, from so-called sea smoke to slushy ocean waves. As atmospheric scientist Scott Denning explains, these striking events are caused mainly by the behavior of water at very cold temperatures.

Why do lake and ocean waters appear to steam during cold snaps?

There are three phases, or states, of water: solid ice, liquid water and gaseous water vapor. Even in extremely cold weather, liquid water can’t be colder than the freezing point – about 32 degrees Fahrenheit – so the surface of the ocean is much warmer than the air above it.

A lot of water evaporates from the warmer ocean into the colder dry air above. As soon as this invisible gas rises even just a little bit above the relatively warm water, it hits air that is much colder and can’t hold much vapor, so the vapor condenses into microscopic droplets of liquid water in the air.

Some people call the wispy clouds caused by condensation just above the winter ocean or lakes “sea smoke.” That’s a better term than steam. Real steam is very hot water vapor – that is, water in its gas phase, which is invisible.

Read the full article, “Steaming lakes and thundersnow: 4 questions answered about weird winter weather,” from The Conversation.

Will Lassman and Jakob Lindaas receive Outstanding Student Paper Awards

Two Ph.D. students were chosen for Outstanding Student Paper Awards from the American Meteorological Society’s 21st Conference on Atmospheric Chemistry. Will Lassman, co-advised by Jeff Collett and Jeff Pierce, was rewarded for presenting his paper, “Methods of Estimating Deposition Using Atmospheric Concentration Measurements: Using Synthetic Observations Downwind of a CAFO to Quantify Ammonia Deposition.” Jakob Lindaas, advised by Emily Fischer, won for presenting his paper, “What Controls the Ratio of Primary Reduced and Oxidized Forms of Gas Phase Reactive Nitrogen in Young Wildfire Smoke?”

Lassman presented results from a study investigating novel measurement platforms for estimating ammonia dry deposition downwind of animal feedlots. He collaborated with Professors Jeff Pierce and Jeff Collett, as well as Professor Jay Ham (soil and crop science) and Azer Yalin (mechanical engineering) to demonstrate a method for estimating the fraction of total ammonia that dry deposits near a source by comparing the dilution of ammonia to that of methane, using Large Eddy Simulation to represent a turbulent atmosphere near the earth’s surface. They also demonstrate how to apply this technique by mounting the sensors on a UAV, or drone.

Lindaas presented preliminary results from his first analyses of WE-CAN campaign data. He is focused on understanding how much ammonia is in wildfire smoke, what happens to it, and how it interacts with other chemistry in wildfire smoke.

“Since the data were so recently collected, I tried to focus on what patterns we have already observed and what kinds of questions they lead to, which I’ve already started to explore,” Lindaas said. “It’s fun to try to tell a story, even/especially when you don’t know how it ends.”

Grad students gain field research experience in Advanced Study Institute program

As a Colorado State University Ph.D. student in atmospheric science, Alexandra Naegele spends most of her days in front of a computer, using models to study clouds, precipitation and atmospheric energy.

For three weeks in November, Naegele left that familiar setting for something wildly different. She was one of 16 graduate students across the U.S. who participated in an intensive, international scientific field campaign in Argentina, observing that region’s famous severe thunderstorms.

Naegele was joined by fellow CSU graduate student Jeremiah Otero Piersante and peers from other institutions in the National Science Foundation-supported International Research Experience for Students Advanced Study Institute: Field Studies of Convection in Argentina. The program was a student-focused, intensive crash course in atmospheric science field work and research held in conjunction with a $30 million, NSF-supported field campaign co-led by CSU faculty.

The overall field campaign, RELAMPAGO, wrapped in December and was the largest land-based atmospheric sciences field study ever conducted outside the United States. RELAMPAGO brought together the expertise of several universities and agencies to discover why thunderstorms in subtropical South America are among the most extreme in the world, regularly producing golf ball or grapefruit-sized hail.

Prof. Maloney leads study on how global warming will affect MJO

Every month or two, a massive pulse of clouds, rainfall and wind moves eastward around the Earth near the equator, providing the tropics their famous thunderstorms.

This band of recurring weather, first described by scientists in 1971, is called the Madden-Julian Oscillation. It has profound effects on weather in distant places, including the United States. Atmospheric scientists have long studied how the Madden-Julian Oscillation modulates extreme weather events across the globe, from hurricanes to floods to droughts.

As human activities cause the Earth’s temperature to increase, reliable, well-studied weather patterns like the Madden-Julian Oscillation will change too, say researchers at Colorado State University.

Eric Maloney, professor in the Department of Atmospheric Science, has led a new study published in Nature Climate Change that attributes future changes in the behavior of the Madden-Julian Oscillation to anthropogenic global warming. Maloney and co-authors used data from six existing climate models to synthesize current views of such changes projected for the years 2080-2100.
