Numerical modeling quantifies seiche oscillations in Lake Onega, suggesting bay inclusion is crucial for accuracy.

To model and analyze barotropic seiche oscillations in Lake Onega using numerical methods.
Applying a linearized system of shallow water equations on a rotating sphere.
Using a high-resolution triangular grid for spatial approximation.
Solving spectral-difference eigenvalue problems for oscillation periods.
Identified seven modes of natural oscillations with specific periods ranging from 4 h 10 min to 13 h 20 min.
Excluding Svyatula bay changed oscillation modes significantly, merging two periods into one with 12 h 30 min.

S.V. Smirnov (2025) studied this question.
