6 FAQs about [Spv systems Antarctica]
Does polar stratospheric ozone affect SPV?
Polar stratospheric ozone has an important influence on the SPV (Previdi & Polvani, 2014; Rao & Garfinkel, 2020; Solomon et al., 2014). Since this study uses the prescribed climatological ozone fields fixed at PI levels in all the simulations, the potential impact of polar stratospheric ozone is not considered.
How did the SPV affect the troposphere and surface climate?
In the geological past, however, how the SPV acted and how it impacted on the troposphere and surface climate remains unclear. This study explores SPV variations in both the Northern and Southern Hemispheres in the past 250 million years (Myr) using simulations of a fully coupled Earth System Model.
Are SPV disruptions directly linked to planetary waves in the stratosphere?
SPV disruptions are directly linked to the upward propagation of planetary waves into the stratosphere (Matsuno, 1971; Polvani & Waugh, 2004; Sjoberg & Birner, 2012). Figures 1e and 1f depict time evolutions of zonal-mean eddy heat flux anomalies at 200 hPa in the three sets of experiments.
How does the stratospheric polar vortex affect surface climate?
At present, influences of the stratospheric polar vortex (SPV) on surface climate have attracted growing attention. In the geological past, however, how the SPV acted and how it impacted on the troposphere and surface climate remains unclear.
How did land-sea distribution asymmetry affect the polar vortex?
This change in land-sea distribution asymmetry led to the substantial enhancement of wave-2 eddy heat flux (Figure 2c), resulting in a sustained weakening of the polar vortex during this period. In the SH, the land fraction at midlatitudes decreased slightly from 250 to 130 Ma and substantially from 120 to 80 Ma (Figure 2d).
Does SPV dissipate?
Hence the SPV as a single vortex has dissipated but the \ (\textrm {CM}\) plots and their coherence allow us to analyze the temporal evolution of spatial structures that lead to this dissipation. As in Fig. 4, but on September 7, 2019 at UTC 0000.
