Time intervals of declining solar activity are dominated by so-called recurrent storms. They are produced mainly by high speed streams (HSS) of the solar wind coming from coronal holes. A HSS is preceded by a co-rotating interaction region (CIR), where the fast stream interacts with slow solar wind. Recurrent magnetic storms are weak but they cause intense chorus activity, which leads to the acceleration of the magnetospheric electrons up to relativistic energies. These effects are comprehensively investigated now by the Van Allen and ERG space missions. Strong variations of interplanetary electric field in HSSs and precipitation of magnetospheric particles at middle and high latitudes disturb the ionosphere, thermosphere and atmosphere for several days or even weeks. This results in significant energy deposition, which is even greater than strong but short transient storms produced by CMEs. The role of recurrent storms in disturbances of the ionosphere, thermosphere and atmosphere has been under intense investigation during the last several years. Presentation of recent experimental results from space missions, such as modern Van Allen Probes, ERG, COSMIC, Swarm etc., ground-based networks as well as prediction of models on these subjects are encouraged.
