Fifty-day moving averages of temperature, density, and velocity of the solar wind obtained in the frameworks of three models: Model 1 (first column), Model 2 (second column), and Model 3 (third column). Blue curves are the model results, red curves are Voyager-2 data, and green curves are the stationary solutions. n_H = 0.05 1/cm³. The yellow area corresponds to the high-speed solar wind from high heliolatitudes, and so this period cannot be compared with the models.
