We describe our first attempt to systematically simulate the solar wind during different phases of the last solar cycle with the Alfven Wave Solar atmosphere Model (AWSoM) developed at the University of Michigan. Key to this study is the  determination of the optimal values of one of the most important input parameter of the model, the Poynting flux, which prescribes the energy flux passing through the chromospheric boundary of the model in form of Alfven wave turbulence. It is found that the optimal value of the Poynting flux parameter is correlated with the open magnetic flux and the area of the open magnetic field regions. These highly linear correlations could shed light on understanding how Alfven wave turbulence accelerates the solar wind during different phases of the solar cycle and estimating the Poynting flux parameter for real-time solar wind predictions with AWSoM.
