| Abstract: |
We investigate the variation in the mode parameters obtained from time series of length nine, 36, 72 and 108 days to understand the changes occurring on different time-scales. The regression analysis between frequency shifts and activity proxies indicates that the correlation and slopes are correlated and both increase in going from time series of nine to 108 days. We also observe that the energy of the mode is anti-correlated with solar activity while the rate at which the energy is supplied remains constant over the solar cycle. |
