摘要

不同速度的太阳风流之间相互作用的区域，被称为旋转相互作用区域，形成了一个几乎一直存在的内日球层结构。利用对GCR调制具有重要意义的日球层主要特征的观测资料，以及旋转相互作用区域的三维MHD建模结果和GCR周期性变化的蒙特卡罗模拟，分析了旋转相互作用区域对日球层经度平均特征和GCR传播的重要性，以及模拟GCR强度长期变化的可能方法。

Manifestation of solar wind corotating interaction regions in GCR intensity variations

The regions of interaction between solar wind streams of different speed, known as corotating interaction regions, form an almost constantly existing structure of the inner heliosphere. Using observational data on the main characteristics of the heliosphere, important for GCR modulation, and the results of 3D MHD modeling of corotating interaction regions, and Monte Carlo simulation of recurrent GCR variations, we analyze the importance of the corotating interaction regions for longitude-averaged characteristics of the heliosphere and GCR propagation, and possible ways for simulating long-term GCR intensity variations with respect to the corotating interaction regions.
