We show examples of excitation of coronal waves by flare-related abrupteruptions of magnetic rope structures. The waves presumably rapidly steepenedinto shocks and freely propagated afterwards like decelerating blast waves thatshowed up as Moreton waves and EUV waves. We propose a simple quantitativedescription for such shock waves to reconcile their observed propagation withdrift rates of metric type II bursts and kinematics of leading edges of coronalmass ejections (CMEs). Taking account of different plasma density falloffs forpropagation of a wave up and along the solar surface, we demonstrate a closecorrespondence between drift rates of type II bursts and speeds of EUV waves,Moreton waves, and CMEs observed in a few known events.
