Upper row: Area-averaged helicity evolution on ROI A and B for AS-78, H-78 and H-25. (a) LNH contour and tangentially projected streamline vectors on ROI A during deceleration peak for AS-78. (b) LNH contour and tangentially projected streamline vectors on ROI A during deceleration peak for H-78. (c) LNH contour and tangentially projected streamline vectors on ROI A during deceleration peak for H-25.
