Connections between the time vs. depth profiles of changes in meridional flow (δUθ) and those in the radial gradient of rotation (﹩\delta (\partial \,\mathrm{log}\,{\rm{\Omega }}/\partial \,\mathrm{log}\,r)﹩). The top and middle panels show δUθ for the northern and southern latitudes (20°, 25°, and 30°), respectively. The north–south symmetric component of changes in δ(∂logΩ/∂logr) is shown in the bottom row for latitudes 10°, 15°, and 20°. The two vertical dashed lines in each panel mark the cycle 24 maximum (2014) and minimum (2020), and the horizontal dotted lines mark the depth 0.97 R. All the results here are from the HMI data.
