Abstract
We present a brief review of the modeling of corotating 3-dimensional features in heliospheric cosmic rays. The model heliosphere incorporates a wavy current sheet and Corotating Interaction Regions (CIRs). We find that present models can qualitatively account for the observed extension of recurrent 26-day cosmic-ray variations to high heliospheric latitudes if perpendicular diffusion is significant. The recurrent enhancement of low-energy (MeV) particles accelerated at CIR-s is also shown to fit into this same picture.
