摘要
The large-scale coronal shock waves observed from radio type II bursts and from Moreton waves have proven surprisingly difficult to detect in coronal images. I review the evidence for such waves in radio, optical, EUV, and soft X-ray images. The data generally support the conclusion that the metric type II bursts can be identified with weak fast-mode shock waves launched at the impulsive phase of the associated flares. Other coronal waves, well seen by EIT, are more closely related to CMEs.
