Vandal Explorer Series: Weather Under an Eclipse

Students Record Gravity Waves Using Weather Balloons

On Dec. 14, 2020, an eight-student team from the NASA Idaho Space Grant Consortium in the College of Engineering were in Chile recording gravity waves produced by the complete solar eclipse. Gravity waves are large disturbances moving through an otherwise stable layer of the atmosphere, and they can influence smaller weather events and air turbulence. Junior Lauren Perla joined the team as a mechanical engineer from Sammamish and explains that understanding gravity waves will help atmospheric scientists improve current weather prediction models. The team practiced measuring the waves throughout Summer 2020. In Moscow, the students launched weather balloons into the atmosphere weekly, and each balloon carries a radiosonde — an instrument designed to radio data on weather phenomena like temperature, wind speed and humidity back to earth. When they traveled to South America, the students spend roughly 18 hours launching one balloon every hour in teams of four. Associate Professor Matthew Bernards in the Department of Chemical and Biological Engineering is the director of the NASA Idaho Space Grant Consortium and oversees the project.

Besides Perla, the team included junior Malachi Mooney-Rivkin in mechanical engineering, junior Alex Chambers in mechanical engineering, senior Leah Davidson in biological engineering, senior Carlos Muñoz in physics, senior Roslyn McCormack in chemical engineering, senior Sebastian Garcia in mechanical engineering and master’s student Jackie Martinez-Alvarez in chemical engineering.
