Области взаимодействия разноскоростных потоков солнечного ветра, известные как коротирующие области взаимодействия, образуют практически постоянно существующую структуру внутренней гелиосферы. Рассмотрены данные наблюдений основных характеристик гелиосферы, важных для модуляции ГКЛ, и результаты трехмерного МГД-моделирования коротирующих областей взаимодействия солнечного ветра и моделирования методом Монте-Карло рекуррентных вариаций ГКЛ. Анализируются важность коротирующих областей взаимодействия для усредненных по долготе характеристик гелиосферы и распространения ГКЛ и возможные пути описания долговременных вариаций интенсивности ГКЛ с учетом коротирующих областей взаимодействия.

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.
