Several unusual features related to the interaction of magnetic clouds with the Earth's magnetosphere as observed on the INTERBALL satellites during 1995–1997 are discussed. The main cause of magnetospheric disturbances is high pressure pulses on leading and trailing edges of clouds. Interaction of clouds with the magnetosphere results in its compression and deformation, large scale motions of the magnetic tail and initiations of substorms and storms. Several important consequences of these processes were (1) observations of magnetcepheric regions and boundaries much closer to the Earth than on average; (2) increases of density and temperature in outer regions of magnetosphere; (3) multiple crossings of geomagnetic tail boundaries presumably due to tail flapping, and (4) bursty fluxes of high energy ions and electrons in the auroral region and polar cap.
