Run A3. Evolution of the peaks of the dynamical terms with heliocentric distance, along x (left) and y (right). The peaks are computed inside the region of non-zero pinch tracer in order to filter out the shock fronts that propagate outwards. The top panels show the absolute value of the main terms: pushing and pulling terms are drawn with black and white filled circles, and magnetic tension with light grey circles; dotted black lines represent the predicted scaling laws for magnetic and kinetic pressure gradient terms as shown in Eq. (22). The bottom panels show the maximum and minimum of the resultant, in green and purple respectively. All the terms are in code units.
