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…
Temporal Variation of Solar Equatorial Rossby Modes with Azimuthal Orders
B. Lekshmi, Laurent Gizon, Kiran Jain +2
We use nearly two decades of helioseismic data obtained from the GONG (2002-2020) and HMI (2010-2020) ring-diagram pipelines to examine the temporal variations of the properties of…
