Temporal variations of solar inertial mode parameters from GONG (2002-2024) and HMI (2010-2024): Rossby modes ($3\le m\le 16$) and $m=1$ high-latitude mode

B Lekshmi, Zhi-Chao Liang, Laurent Gizon +2

We studied the temporal evolution of solar inertial modes over the solar cycle using observations from GONG and SDO/HMI. We focused on the high-latitude mode with azimuthal wavenum…
