论文摘要
太阳风模型的输入在1 AU处的准确太阳风预测中起着重要作用。这项工作引入了由发电机模型产生的合成磁图作为磁流失动力学（MHD）模拟的输入。我们进行了一项定量研究，该研究比较了观察到的太空天气建模框架（SWMF）的结果和合成太阳能图输入。对于每种情况，我们都会比较极端超紫色（EUV）图像的结果，并沿着地球轨迹提取模拟数据，以与原位观测值进行比较。我们在太阳周期23和24内使用真实和合成磁力图初始化SWMF，以进行一组Carrington旋转（CR）。我们的结果有助于量化Dynamo模型用作太阳风模型的输入的能力，从而为1 Au以1 Au的太阳风提供预测。
The input of the Solar wind models plays a significant role in accurate solar wind predictions at 1 AU. This work introduces a synthetic magnetogram produced from a dynamo model as an input for Magnetohydrodynamics (MHD) simulations. We perform a quantitative study that compares the Space Weather Modeling Framework (SWMF) results for the observed and the synthetic solar magnetogram input. For each case, we compare the results for Extreme Ultra-Violet (EUV) images and extract the simulation data along the earth trajectory to compare with in-situ observations. We initialize SWMF using the real and synthetic magnetogram for a set of Carrington Rotations (CR)s within the solar cycle 23 and 24. Our results help quantify the ability of dynamo models to be used as input to solar wind models and thus, provide predictions for the solar wind at 1 AU.
