| Figure 3 The evolution of polar 70.5-90#cod#x000b0;N zonal-mean zonal wind contours at 10 hPa units: m s -1 in 32 years: the start black solid line and end black dash line dates of the ST at 70.5#cod#x000b0;N, 10 hPa; and the stratospheric final warming SFW date red solid line and the date of vortex displacement stratospheric sudden warming SSW events black circles and vortex split SSW events black dots. All the variables correspond to the left coordinate. The duration of the ST white dashed line corresponds to the right coordinate units: day. |
