The distributions the fluctuations of magnetic field strengths B(t) observed on a scale of a year in the heliosphere between 1 AU and 90 AU are approximately lognormal. The PDFs of the corresponding increments of B(t) are Tsallis distributions on scales from 1 hr—128 days between 1 and 90 AU. A deterministic MHD model predicts these results. The model predicts that small chaotic structures merge to form large structures. There is a “phase transition” near ∼40 AU at which the there is a change from growth to decay. Between R∼40 and 85 AU the solar wind is in a quasi‐equilibrium state described by a “q‐triplet”. |
