  4. Depiction of model-produced meridional circulation beneath solar surface

    Next step toward predicting Sun’s cycles

    A leading goal of solar scientists is to improve predictions of the Sun's approximately 11-year cycle. New research led by scientists from NCAR and Sweden shows how solar predictions can borrow from weather forecasting techniques in order to predict the timing and extent of the solar cycle.
