  15. Summary • 6 continuous years of GONG meridional circulation confirm previous results showing “extra circulation” in active belts. • Removing active longitudes. • global circulation pattern in the active belt • inflows that plays a role in active region production • Time-distance validation --> Work in progress

  16. Checking the averages
