Flow makes the spectral problem non-self-adjoint, so that the spectrum can become overstable. The criteria for cluster spectra to appear are derived analytically and both stable and unstable sides of the spectrum are examined numerically. Above certain critical values of the shear flow at the resonant surface, the gravitating interchange modes disappear However, the local extrema of the continua can then take over the cluster spectrum.}, year = {1999}, journal = {Journal of Plasma Physics}, volume = {61}, pages = {221-240}, month = {Feb-Mar}, isbn = {0022-3778}, doi = {10.1017/s0022377898007454}, language = {eng}, }
