We qualitatively examine the effects of changes in the solar wind dynamic pressure on the structure of a centrifugally driven planetary wind from Jupiter. We suggest that dynamic pressure variations can induce a transition between a super‐Alfvenic wind and sub‐Alfvenic breeze on Jupiter's dayside, which could possibly account for the observed large scale changes in the structure of Jupiter's outer magnetosphere.
