New Climate Model to Be Built from the Ground Up

12-13-18

"Projections with current climate models—for example, of how features such as rainfall extremes will change—still have large uncertainties, and the uncertainties are poorly quantified," says Professor Tapio Schneider, principal investigator of the Climate Modeling Alliance (CliMA). "For cities planning their stormwater management infrastructure to withstand the next 100 years' worth of floods, this is a serious issue; concrete answers about the likely range of climate outcomes are key for planning." The new climate model will be built by a consortium of researchers led by Caltech, in partnership with MIT; the Naval Postgraduate School (NPS); and JPL, which Caltech manages for NASA. It will use data-assimilation and machine-learning tools to improve itself in real time, harnessing both Earth observations and the nested high-resolution simulations. "The success of computational weather forecasting demonstrates the power of using data to improve the accuracy of computer models; we aim to bring the same successes to climate prediction," says Professor Andrew Stuart.

Capturing Clouds

07-12-17

Professor Tapio Schneider has helped bring artist Karen LaMonte's cloudy vision to life. "I thought it was a great idea," says Schneider, whose work focuses on reducing uncertainties in climate change projections—in part through modeling cloud formation to better understand clouds' impact on the environment. Collaborating with LaMonte, he reasoned, could help raise awareness of these issues. "Clouds are hugely important for the climate," says Schneider. "How much warmer it will get depends on what happens to cumulus clouds like those Karen was interested in. " [SoCaltech story]

New Computer Model Explains Lakes and Storms on Titan

01-05-12

A new computer model of the atmosphere and methane cycle of Titan, Saturn's largest moon, explains baffling observations of its lakes and storms. "We have a unified explanation for many of the observed features," says Tapio Schneider, the Frank J. Gilloon Professor of Environmental Science and Engineering. "It doesn't require cryovolcanoes or anything esoteric." [Caltech Press Release]

Linde Center's New Home Makes Headlines for Extraordinary Renovations

07-12-11

The Ronald and Maxine Linde Center for Global Environmental Science's new home, the Linde + Robinson Laboratory, will be the nation's first LEED Platinum laboratory and is profiled in Solutions Journal, a magazine of the Rocky Mountain Institute. The center is directed by Tapio Schneider, Frank J. Gilloon Professor of Environmental Science and Engineering, and brings together faculty from different Caltech Divisions who study climate change.  [Caltech Feature] [Magazine Article]

Warm Water Causes Extra-cold Winters

03-30-11

Tapio Schneider, Frank J. Gilloon Professor of Environmental Science and Engineering, and Dr. Yohai Kaspi have found a mechanism that helps explain why average winter temperatures in northern Europe are at least 10 degrees Fahrenheit warmer than similar latitudes on the northeastern coast of the United States. Using computer simulations of the atmosphere, they have found that the warm water off an eastern coast will heat the air above it and lead to the formation of atmospheric waves, drawing cold air from the northern polar region. The cold air forms a plume just to the west of the warm water. In the case of the Atlantic Ocean, this means the frigid air ends up right over the northeastern United States. [Caltech Press Release]

Tapio Schneider and Colleagues Discover Storms in the Tropics of Titan

08-12-09

Tapio Schneider, Professor of Environmental Science and Engineering, and his colleagues have discover storms on Saturn's largest moon, Titan, which is generally "a very bland place, weatherwise," says Mike Brown, Richard and Barbara Rosenberg Professor and Professor of Planetary Astronomy. "The first cloud was seen near the tropics and was caused by a still-mysterious process, but it behaved almost like an explosion in the atmosphere, setting off waves that traveled around the planet, triggering their own clouds. Within days a huge cloud system had covered the south pole, and sporadic clouds were seen all the way up to the equator." Schneider, an expert on atmospheric circulations, was instrumental in helping to sort out the complicated chain of events that followed the initial outburst of cloud activity.

EAS Faculty Cited in Discover Magazine's 50 Best Brains in Science Issue

11-14-08

Discover magazine recently published its annual 50 Best Brains in Science issue, and the "20 Under 40" list which highlights "a new generation of innovators changing the way we think about everything from theoretical mathematics to cancer therapy." Four researchers from Caltech (three from EAS) were cited: Michael Elowitz (Assistant Professor of Biology and Applied Physics; Bren Scholar; Investigator, Howard Hughes Medical Institute), Sarkis Mazmanian (Assistant Professor of Biology), Tapio Schneider (Associate Professor of Environmental Science and Engineering), and Changhuei Yang (Assistant Professor of Electrical Engineering and Bioengineering).

Simona Bordoni and Tapio Schneider Offer New Explanation for Monsoon Development

07-25-08

Tapio Schneider, Associate Professor of Environmental Science and Engineering, has come up with a new explanation for the formation of monsoons. Schneider and colleague Simona Bordoni, who will start as an assistant professor at Caltech in 2009, propose an overhaul of a theory about the cause of the seasonal pattern of heavy winds and rainfall that essentially had held firm for more than 300 years.
