             abstract = "The interaction between the disturbed solar wind and the 
                         geomagnetic field gives rise to different physical processes that 
                         can significantly affect technological systems as well as human 
                         life. Here we investigate the role of a complex solar structure, a 
                         corotating interaction region (CIR) followed by magnetic field 
                         Alfv{\'e}nic fluctuations in the generation of disturbances in 
                         the inner magnetosphere. These disturbances are observed in terms 
                         of the power spectral density (PSD) of the ultra low frequency 
                         waves (ULF) in the nightside, equatorial region. Several studies 
                         show the correlation between CIRs followed by Alfv{\'e}nic 
                         fluctuations and the generation of ULF waves in the internal 
                         magnetosphere. However, until now it is not straightforward to 
                         decisively say which solar wind parameters or which combinations 
                         thereof are most effective in causing disturbances in the inner 
                         magnetosphere, or how each part of the complex interplanetary 
                         structure influences the most the temporal evolution of the 
                         magnetosphere. Using global MHD simulations we try to address some 
                         of these questions. Firstly, we use the magnetic field and plasma 
                         parameters of a real, complex CIR+Alfv{\'e}nic fluctuations event 
                         as input to the SWMF/BATS-R-US code and then calculate from the 
                         model outputs the PSD of ULF waves in the aforementioned region. 
                         Then, we separate the complex event into its constituent parts by 
                         building synthetic magnetic field and plasma profiles based on the 
                         physical parameters that characterize each of these parts. The MHD 
                         code is then fed with each new synthetic profile to provide ULF 
                         PSDs that are compared with those from the simulation with real 
                         solar wind inputs. This numerical experiment will help us to 
                         understand which solar wind parameters contribute the most for the 
                         ULF waves activity in the nightside magnetosphere. We expect to 
                         provide important information for future forecasting studies of 
                         ULF wave activity in the Earths magnetosphere whenever the 
                         geospace is under the influence of recurrent events as the one 
                         analyzed here.",
