My work consisted in defining a metric to compare the trajectories of the balloons and correlating the velocities of the balloons to deduce the intrinsic frequency of the gravity waves by using the Fourier Transform. Besides the use of rigor and logic, what I enjoyed most about this research internship was applying mathematics and computer science to solve a real-world problem, related to a physical concept. By the end of this internship, I was able to obtain a deeper understanding of orographic gravity waves while giving feedback on the limits of the simulation they had developed, along with some advice on how to improve it. The work led to important advances in the project and to a conference on gravity waves in Frankfurt, Germany, in March 2022.
