Using Flare-Induced Modulation of Three- and Five-Minute Oscillations for Studying Wave Propagation in the Solar Atmosphere

A flare happening up in the corona will create hydromagnetic waves as it distorts the field. Here we see a time sequence illustrating the interesting possibility that these waves can alter the physical properties of the lower atmosphere, which already contain wave power in the p-mode (5-minute) band. This could explain recent observations of flare-initiated chromospheric "oscillations". The downward-moving waves can also transport energy by analogy with the Poynting vector. Momentum conservation, relating flare/CME mass flows of different kinds, also has a similar timeline.
