This paper deals with the research of magnetic cloud (MC) on five aspects including observations, theoretical models, MHD simulations, interaction of shock with preceding MC, and multiple magnetic clouds. During the solar maximum, a majority of non-recurrent geomagnetic storms are related to magnetic clouds. Specially, the recent research suggests that the compressed magnetic clouds might be able to cause much larger geomagnetic storms. Thus, further understanding of magnetic clouds is valuable for space weather research and helpful to improve the prediction level of great geomagnetic storms.
