In the Northern Hemisphere (NH), SSWs occur on average every other year and often lead to persistent blocking over Greenland associated with the negative phase of the North Atlantic Oscillation (NAO)12,13, altering surface weather for weeks to months14.

Atmosphere News -- ScienceDaily Further stratospheric influences on surface variability and extremes will likely emerge in future studies. The stratosphere exhibits an overall slower evolution and longer predictability as compared to the troposphere4, and a downward influence from the stratosphere can thus contribute to persistent and predictable changes at the surface on timescales of weeks to years. 129.

So it pushes the air against the jet streams flow, and it weakens the jet stream. Stroeve, J. et al. Because of this, jet aircraft and weather balloons reach their maximum operational altitudes within the stratosphere. As the wave grows, it reaches a point where it turns over and breaks, like a wave hitting a beach. Sigmond, M., Reader, M. C., Fyfe, J. C. & Gillett, N. P. Drivers of past and future Southern Ocean change: stratospheric ozone versus greenhouse gas impacts. Thus, the stratosphere can act as a driver of surface weather and a source of predictability for lead times longer than two weeks. A better understanding of the vertical coupling in the atmosphere, along with improved representation in numerical models, is therefore expected to help predict extreme events on timescales from weeks to decades in terms of the event type, magnitude, frequency, location, and timing. Seasonal evolution of stratosphere-troposphere coupling in the Southern Hemisphere and implications for the predictability of surface climate. The values are averaged over the 45-day period following a case of an extreme weak vortex event in each hemisphere, i.e., the period from 13 February 2018 to 29 March 2018 in the Northern Hemisphere and 26 September 2002 to 9 November 2002 using data from the NCEP/NCAR reanalysis132. & Knight, J. R. European climate extremes and the North Atlantic Oscillation. The full spectrum and amplitude of wave coupling linking the troposphere and the stratosphere is also not well represented or poorly parameterized119,120. Because the air temperature in the stratosphere slowly increases with altitude, it does not cause convection and has a stabilizing effect on atmospheric conditions in the region. Geophys. Amer. More coupled atmosphere-ocean climate models are able to internally generate the Quasi-biennial Oscillation, but biases in the vertical extent and amplitude persist.

The layer directly below the exosphere is the thermosphere; the boundary between the two is called the thermopause. However, in the NH, the amplified surface warming in the Arctic reduces the surface equator-to-pole temperature gradient at the surface and shifts the storm tracks equatorward, leading to a tug of war between the upper and lower tropospheric temperature gradient changes123,124,125.

Beyond the stratospheres influence on surface climate, it is less well recognized that the stratosphere can contribute to tropospheric extremes.

Chlorine atoms are not consumed in the reaction. The event seems to have destabilized the polar vortex enough that a weaker stratospheric wobble a week or so later triggered a full-on disruption and sudden stratospheric warming event. Geophys.

It remains unclear whether this variability in NH polar vortex strength is anthropogenically forced (e.g., via declining Arctic sea ice and amplified Arctic warming due to increased greenhouse gases43,44), or if it represents internal variations of the coupled atmosphere-ocean system45. Different structures of the stratospheric polar vortex can have unique impacts on surface extremes over Eurasia and North America.
