Spatial distribution and physical characteristics of decomposed sunspot wave modes

Sunspot oscillations consist of multiple wave modes, making it challenging to isolate individual physical processes. To decompose these multi-modal oscillations, we apply empirical mode decomposition (EMD) to Hα Doppler velocity data obtained with the Fast Imaging Solar Spectrograph. By avoiding arb...
