Lake-effect fame spreads abroad

Winter break’s heavy snows and a radar-lugging vehicle known as a Doppler-on-Wheels have enabled Professor Scott Steiger ’99 and several meteorology students to witness never-before-seen phenomena — like a line of seven tornado-like waterspouts in one lake-effect storm — and to collect unique data.

The first-of-its-kind use for the million-dollar vehicle — best known for chasing tornados in Discovery Channel programs — also has attracted local media, national scientific press and international filmmaking attention.

cott Steiger ’99, center, assistant professor of meteorology, explains uses of the rolling radar and laboratory known as a Doppler-on-Wheels to Charles Colville, director, left, and Helen Czerski, physicist and presenter, of a British Broadcasting Corp. team in Oswego this January for a segment of an upcoming Discovery Channel series titled “23 Degrees.”

A six-person British Broadcasting Corp. crew filmed Oswego’s lake-effect chasers one January weekend for a planned Discovery Channel series called “23 Degrees,” a yearlong global journey in search of stories to reveal Earth’s relationship with the sun. (The title refers to the tilt of Earth’s axis in relationship to the sun.)

Director Charles Colville, physicist and presenter Helen Czerski and coworkers “enjoyed” perfect conditions for their planned
segment on the prodigious snow machines that Steiger has named long-lake axis parallel (LLAP) lake-effect storms. It was
a cold, busy weekend.

The crew arrived in Oswego Thursday night Jan. 13 and spent Friday and Saturday filming an exhaustive series of scenes and interviews — including some with a helicopter — before following Steiger, Josh Wurman of the Center for Severe Weather Research in Boulder and meteorology students as they chased a storm that dumped up to 20 lake-effect inches on Oswego County and its neighbors.

Steiger and co-principal investigator Al Stamm, distinguished service professor and earth sciences chair, won an $86,000 National Science Foundation grant and the loan of NSF-owned equipment like the DOW.

The DOW’s dual polarimetric radar — it scans vertically as well as horizontally — enables the scientists to measure the speed of descent of particles in the storm, allowing categorization and, eventually, Steiger trusts, a better tool for predicting the volume of snow and the duration of storms.

Media attention followed the DOW nearly since it arrived in mid-December. Oswego High School students heard a talk by Steiger and toured the vehicle on Dec. 21; reporter Racquel Asa of WSYR-TV in Syracuse followed the DOW in action on Jan. 4; and a Jan. 11 NSF feature story on Oswego’s research ran on a variety of websites, including one in Germany.

NSF fuels snow hunt

An $86,000 grant from the National Science Foundation will provide SUNY Oswego meteorology faculty member Scott Steiger ’99 and his students the tools to chase the most intense snowstorms and collect first-of-its-kind data.

Meteorology Professor Scott Steiger ’99 shows images of the Doppler-on-Wheels truck and the data it will collect.

The grant will provide a radar-carrying truck from the NSF called Doppler-on-Wheels for the snowstorm-chasing season, and experts from Boulder, Colo., will train the students in its use in the month before startup. Jeffrey Frame of the University of Illinois, a colleague of Steiger’s with a lot of experience with the vehicle and instruments, is a co-principal investigator on the grant.

Steiger, who spends his summers chasing tornadoes in the Midwest, forecasts little chance that this winter will be as quiet as last. He, distinguished service professor Al Stamm and up to 14 meteorology majors staffing the project should have plenty to study.

“It’s better than a tornado project, because the chance of catching a significant tornado on the ground is quite small,” said Steiger.

Data gathering will run from late December to early February this season, Steiger said. Lake-effect conditions set up early in the winter, when Lake Ontario’s waters still hold summer warmth and icy cold winds blow out of the west and northwest.

Data analysis and writing for the project will take place next spring and summer, followed by publication and conference presentations in the second year of the grant.

If the data-collection effort and results warrant, Steiger said he plans in time to apply for a larger grant, which would fund the use of aircraft and other instruments as well as the Doppler-on-Wheels.
