             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. The goal of this work is to investigate the role of a 
                         complex solar structure, i.e., a corotating interaction region 
                         (CIR) followed by solar winds magnetic field Alfv{\'e}nic 
                         fluctuations, in the generation of disturbances in the inner 
                         magnetosphere in terms of the power spectral density (PSD) of the 
                         ultra low frequency waves (ULF) in the nightside, equatorial 
                         region. There are several studies that show the correlation 
                         between fluctuations of solar winds magnetic field and plasma 
                         parameters characteristic of CIRs and Alfv{\'e}nic fluctuations 
                         and the corresponding generation of ULF waves in the internal 
                         magnetosphere. However, some issues remain, namely, during such a 
                         complex event 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 
                         magnetohydrodynamical (MHD) simulations we perform a study which 
                         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, as far as MHD simulations 
                         are concerned, and which combination of these synthetic parameters 
                         can reproduce the results obtained when running the MHD code with 
                         input data from the actual event. This work might also 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.",
