Abstract

A dynamic galactic cosmic ray model is proposed to quantitatively describe the z=1-28 ions and electrons of E=10-10(5) MeV/nucleon and their particle flux variations around the Earth's orbit and beyond the Earth's magnetosphere due to diverse large-scale variations of solar activity factors. The variations of large-scale heliospheric magnetic fields and the galactic cosmic ray flux variation time delays relative to solar activity variations are simulated. The lag characteristics and sunspot number predictions having been determined in detail, the model can be used to predict galactic cosmic ray flux levels.

摘要

提出了一种动态银河宇宙射线模型，以定量描述能量为E=10-10(5)MeV/核子的z=1-28离子和电子，以及由于太阳活动因素的各种大规模变化，它们在地球轨道周围和地球磁层之外的粒子通量变化。模拟了大规模日球层磁场的变化以及银河宇宙射线通量变化相对于太阳活动变化的时间延迟。在详细确定了滞后特征和太阳黑子数预测之后，该模型可用于预测银河宇宙射线通量水平。
