Moreton waves, observed in Hα, and the recently discovered coronal transients known as "EIT waves" have remained fairly poorly understood phenomena. In particular, the issues of their mutual association and of the nature of their driver are not resolved. We discuss seven Moreton waves observed in Hα and derive their basic characteristics. Four of these events were observed simultaneously in Hα and EUV. A deceleration of the disturbances is found in all cases. In the 2 May 1998 event, the cospatiality of Moreton and EIT wave fronts is established and a detailed analysis of the evolution of the Hα wave, its kinematics and perturbation profile is carried out. The results - deceleration, broadening, and decrease of intensity of the profiles - favor the fast-mode shock ("blast wave") scenario over the CME-associated magnetic field evolution hypothesis.
