Sudden stratospheric warming. A sudden stratospheric warming (SSW) is an event in which polar stratospheric temperatures rise by several tens of kelvins (up to increases of about 50 °C (90 °F)) over the course of a few days. [ 1] The warming is preceded by a slowing then reversal of the westerly winds in the stratospheric polar vortex.
The stratospheric polar vortex breaks down in Spring as the polar night ends. A sudden stratospheric warming (SSW) is an event that occurs when the stratospheric vortex breaks down during winter, and can have significant impacts on surface weather. [citation needed]
Climate change in Antarctica, 2023–2024 El Niño event. The 2024 Antarctica heat wave refers to a prolonged and significant mid- winter increase in Antarctic temperatures compared to prior winters, causing several regions of Antarctica to reach temperatures 10 °C (18.0 °F) above normal in July 2024, up to a 28 °C (50.4 °F) increase above ...

The January–March 2014 North American cold wave was an extreme weather event that extended through the late winter months of the 2013–2014 winter season, and was also part of an unusually cold winter affecting parts of Canada and parts of the north-central and northeastern United States. [5] The event occurred in early 2014 and was caused ...
The stratosphere ( / ˈstrætəˌsfɪər, - toʊ -/) is the second-lowest layer of the atmosphere of Earth, located above the troposphere and below the mesosphere. [ 2][ 3] The stratosphere is composed of stratified temperature zones, with the warmer layers of air located higher (closer to outer space) and the cooler layers lower (closer to the ...
This method of geo-engineering involves artificially adding aerosols such as sulphate into the stratosphere, which extends from 6-12 miles (10-20km) to 31 miles (50km) above the Earth. These ...
