Abstract
Supplementary animation for: "The major stratospheric final warming in 2016: Dispersal of vortex air and termination of Arctic chemical ozone loss" Authors: Gloria L. Manney, and Zachary D. Lawrence Journal: Atmospheric Chemistry and Physics (ACP) This animation shows the evolution of the “horseshoe” patterns seen in scatterplots of function M versus scaled potential vorticity (sPV) that are shown for a few days in the main text (Figs 9-11) during the major final warming period from 24 February to 15 April at 490 (left), 550 (middle), and 850 K (right). The vertical red lines plotted are the sPV values used to define the vortex edge in CAVE-ART, which correspond to 1.4 x 10^-4 s^-1 for 490 K, 1.62 x 10^-4 s^-1 for 550 K, and 1.94 x 10^-4 s^-1 for 850 K. Note that the units for the function M (y-axes) are distances in megameters (Mm, 10^6 m), and that the limits of the x and y axes are different for each isentropic surface.
