This makes the model heavily overconstrained by observation and readily tested. Here I first outline the model, and then concentrate on how the model answers objections raised since publication - with many of the tests being reported at this meeting. I then begin to explore how these and future tests can discriminate between this wind model and 3 well-defined alternatives.12 pages, 3 figures.
