Cosmic ray intensities and density gradients, as observed by the Pioneer 10 and 11, Voyager 1 and 2, and IMP 8 spacecraft during the 1977 and 1987 solar minimum periods, are interpreted in terms of a two‐dimensional version of the cosmic ray transport equation that includes drifts. This paper is a follow‐up of an earlier no‐drift version to elucidate the necessity and limitations of drift effects as demanded by actual observations.
