Severns' article "Verticals, Ground Systems and Some History",
July 2000, p. 39, quotes the following: "As indicated in Figure 1,
the tangential component of the H field (H(phi)) induces
horizontal currents (Ih) flowing radially and the normal
component of the E field (Ez) induces vertically flowing
currents (Iv). The paper is available for download
from www.arrl.org.

Thanks for the reference, but it makes no mention of circumferential
currents. At first glance, figure 1 seems to show a circumferential Ih,
but the text (as you quoted) clearly calls this a radial current -- the
circle in figure 1 turns out to be Hphi, circling the vertically
directed current.
