Temporal variations of solar inertial mode parameters from GONG (2002-2024) and HMI (2010-2024): Rossby modes () and 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…

Dynamics of Subsurface Flows in Solar Active Regions During the May 2024 Storm
B Lekshmi, Sushanta Tripathy, Kiran Jain +1
In May 2024, the Sun exhibited intense magnetic activity, marked by numerous high-intensity flares resulting from the interaction and merging of NOAA ARs 13664 and 13668 in the sou…

Solar Inertial Modes
Laurent Gizon, Yuto Bekki, Aaron C. Birch +5
The Sun's global inertial modes are very sensitive to the solar differential rotation and to properties of the deep solar convection zone which are currently poorly constrained. Th…
