太阳日冕的波动和振荡活动是有信心地观察与现代成像和光谱仪器在可见光，EUV，X射线和无线电波段，并解释磁流体动力学（MHD）波理论。评论反映了当前的趋势，在观测研究的日冕波和振荡（立扭，香肠和纵向模式，传播慢波和快波列，搜索扭转波），理论建模的相互作用的MHD波等离子体结构，和实施的理论结果的模式识别。还讨论了利用MHD波对日冕等离子体进行远程诊断的方法-- MHD日冕地震学，并论证了这种方法对估算日冕磁场、输运系数、精细结构和加热函数的适用性。
Wave and oscillatory activity of the solar corona is confidently observed with modern imaging and spectral instruments in the visible light, EUV, X-ray and radio bands, and interpreted in terms of magnetohydrodynamic (MHD) wave theory. The review reflects the current trends in the observational study of coronal waves and oscillations (standing kink, sausage and longitudinal modes, propagating slow waves and fast wave trains, the search for torsional waves), theoretical modelling of interaction of MHD waves with plasma structures, and implementation of the theoretical results for the mode identification. Also the use of MHD waves for remote diagnostics of coronal plasma — MHD coronal seismology — is discussed and the applicability of this method for the estimation of coronal magnetic field, transport coefficients, fine structuring and heating function is demonstrated.
