7 kwi 2021 · On 5 January 2021, the Arctic stratospheric polar vortex dramatically weakened, and the temperature of the Arctic stratosphere rapidly increased in an event known as a major sudden stratospheric warming (SSW).
1 sie 2021 · Using the ERA5 reanalysis, sea surface temperature and sea ice observations, and the real-time multivariate Madden–Julian index, this study explores a sudden stratospheric warming (SSW) in ...
13 paź 2021 · Using reanalysis, observations, and subseasonal to seasonal (S2S) forecasts, the most recent sudden stratospheric warming (SSW) in January 2021 and its predictability are explored. Previous work has shown that SSWs can be forecasted at relatively long lead time if favorable conditions are present.
21 paź 2020 · A particularly extreme case of stratospheric vortex weakening is known as a sudden stratospheric warming (SSW), thus called because of the rapid rise in the temperature of the polar stratosphere (~50°C in a few days). Associated with the rapid rise in temperature is a dramatic deceleration of the polar night jet.
3 sie 2024 · We examine four global average temperature indicators (see Methods): GSAT and three well-established satellite-observable atmospheric layers covering the temperature lower stratosphere...
23 lis 2020 · Our understanding of sudden stratospheric warmings has accelerated recently, particularly the predictability of surface weather effects. More observations, improved climate models, and big data methods will address uncertainties in key aspects of sudden stratospheric warmings.
28 lip 2021 · Using the ERA5 reanalysis, sea surface temperature and sea ice observations, and the real-time multivariate Madden–Julian index, this study explores a sudden stratospheric warming (SSW) in January 2021, its favorable conditions, and the near surface impact.
