Numerical Methods for Calculating Atmospheric Latent Release Completed

Designed a finite difference scheme to solve the Adiabatic Heating Equation (an elliptic equation describing latent release) of the Quasi-Geostrophic Equation Set in a parallelized manner. Leveraged the spectral spherical harmonics method to improve convergence, applying techniques from Scientific Computation (lectured by Alexander Kurganov). Supervised by Dr. Li Dong.
