Alumna pairs passions for writing, science at Weather Channel website

Five years since graduating from the University of Delaware, Laura Dattaro is right where she belongs. Not playing the trumpet professionally, as she assumed she would be entering her freshman year of college, but writing for The Weather Channel at weather.com, immersed in the two things she loves most: writing and science.

Dattaro never thought she would be a journalist. Majoring in English and music and playing for the UD Marching Band, the Honors Program student had ambitions to make music her main career focus. That was until a fellow band member and city news desk editor at The Review, UD’s student run newspaper, gave her a story to work on. (more…)

Stormy Stars? NASA’s Spitzer Probes Weather on Brown Dwarfs

Swirling, stormy clouds may be ever-present on cool celestial orbs called brown dwarfs. New observations from NASA’s Spitzer Space Telescope suggest that most brown dwarfs are roiling with one or more planet-size storms akin to Jupiter’s “Great Red Spot.”

“As the brown dwarfs spin on their axis, the alternation of what we think are cloud-free and cloudy regions produces a periodic brightness variation that we can observe,” said Stanimir Metchev of the University of Western Ontario, Canada. “These are signs of patchiness in the cloud cover.” (more…)

NASA to Launch Ocean Wind Monitor to Space Station

PASADENA, Calif. – In a clever reuse of hardware originally built to test parts of NASA’s QuikScat satellite, the agency will launch the ISS-RapidScat instrument to the International Space Station in 2014 to measure ocean surface wind speed and direction.

The ISS-RapidScat instrument will help improve weather forecasts, including hurricane monitoring, and understanding of how ocean-atmosphere interactions influence Earth’s climate. (more…)

UD’s Wang contributes invited paper on cloud microphysics

Lian-Ping Wang, professor of mechanical engineering and joint professor of physical ocean science and engineering at the University of Delaware, recently published an invited critical review paper in the 2013 volume of the Annual Review of Fluid Mechanics, a high impact journal for the fluid mechanics community.

Co-authored with Wojciech Grabowski, a senior scientist from the National Center for Atmospheric Research (NCAR), the paper, titled “Growth of Cloud Droplets in a Turbulent Environment,” addresses a classic cloud physics problem of how cloud turbulence affects the growth of tiny cloud droplets.

MU Students Gain Experience with Advanced Weather Tracking Technology

Students use tornado-chasing technology to research rain’s impact on stream

COLUMBIA, Mo. – With advances in meteorology technology, predicting storms is becoming easier than in the past. While most meteorology students learn about these new technologies in the classroom and don’t get a chance to use sophisticated equipment until they are on the job, a group of University of Missouri students were able to test a mobile weather tracking device, Doppler on Wheels (DOW), made famous by shows such as Discovery Channel’s Storm Chasers.

The DOW visiting MU is one of a fleet of radar trucks maintained by the Center for Severe Storm Research. Each radar truck is mounted with a Doppler weather radar dish. The fleet also consists of a support vehicle and three trucks that deploy instruments to track weather patterns in tornadoes and hurricanes. One of the radar trucks was brought to MU so that students could learn about the technology first-hand. (more…)

MU Expert Predicts Hot, Dry Summer for Midwest

COLUMBIA, Mo. – For nearly a year, the Midwest and southwest United States have experienced drought and warmer than normal conditions. A University of Missouri expert is predicting no relief, as he expects drought and hot conditions to continue this summer.

“I expect one of two scenarios to play out; the first is a continued La Nina climate pattern to affect our weather this summer,” said Tony Lupo, professor and chair of the Department of Atmospheric Science in the School of Natural Resources. “This will lead to a drought and above average heat throughout the Midwest from Texas to Iowa, where farmers with parched fields can least afford dry conditions. However, it is also possible that a new El Nino pattern could develop this fall. While I don’t see this happening, it would bring more favorable temperatures and precipitation patterns to the Midwest.” (more…)

A Better Way to ID Extreme Weather Events in Climate Models

*Berkeley Lab scientists help automate the search for hurricanes and other storms in huge datasets*

You’d think that spotting a category 5 hurricane would never be difficult. But when the hurricane is in a global climate model that spans several decades, it becomes a fleeting wisp among mountains of data.

That’s a problem. As scientists develop ever-more sophisticated computer models to predict the effects of climate change, one of the things they’ll look for are changes in the frequency of extreme weather events such as hurricanes and heavy precipitation. The more data generated by models, however, the more difficult it is to quantify these rare but potent events. (more…)

COLUMBIA, Mo. — One hundred fifty years ago, two armies battled each other and the weather in Missouri’s first significant Civil War battle. While the battle’s course is familiar to historians, virtually no scientific data exists about the atmospheric conditions that influenced the fighting. In a project that blends history, sleuthing and modern weather analysis, Tony Lupo, professor and chair of the Department of Atmospheric Sciences at the University of Missouri, and Mike Madden, a meteorology student, have scientifically examined the heavy rains that hampered the union forces, eventually leading to a costly defeat.
