Description:
The work of Isenberg and Jokipii (1979) is examined and it is shown that their extension of the conventional drift-flux formula to static magnetic fields of arbitrary spatial variation is invalid for interplanetary cosmic-ray transport. A field configuration involving helical magnetic fields which suppresses curvature and gradient drift and which may occur in the solar wind is presented. It is concluded that the conventional drift-flux contribution to the solar modulation of cosmic rays may, but need not, be important.
