Abstract

Data from observations of the photospheric magnetic field at a number of ground stations (STOP, WSO, GONG) and by the SDO/HMI satellite for 2014–2019 are examined in terms of the accuracy of the model calculations of the speed of calm solar wind and the areas of coronal holes obtained on their basis. A high positive correlation was found (R > 0.5) between the simulation results and satellite observations (ACE, SDO/AIA193) for separate time periods. The best results in the modeling of the speed of the calm solar wind are given by the data from the ground stations WSO and STOP (Kislovodsk Mountain Astronomical Station, 2014). The temporal variability of the empirical coefficients of the model used in the forecasts was determined.

冠状孔和太阳风参数模拟附录中地面和卫星对光球磁场观测的比较分析

摘要

根据平静太阳风速度模型计算的准确性，研究了2014-2019年来自多个地面站（STOP，WSO，GONG）和SDO / HMI卫星的光球磁场观测数据以及根据其获得的冠状孔面积。在单独的时间段内，模拟结果与卫星观测值（ACE，SDO / AIA193）之间发现高度正相关（R > 0.5）。来自地面站WSO和STOP（基斯洛沃茨克山天文站，2014）的数据给出了对太阳风速模拟的最佳结果。确定了预测中使用的模型的经验系数随时间的变化。
