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 average. The heat wave was significant for occurring ...
Polar vortex. A circumpolar vortex, or simply polar vortex, is a large region of cold, rotating air; polar vortices encircle both of Earth's polar regions. Polar vortices also exist on other rotating, low- obliquity planetary bodies. [1] The term polar vortex can be used to describe two distinct phenomena; the stratospheric polar vortex, and ...
Polar amplification. Polar amplification is the phenomenon that any change in the net radiation balance (for example greenhouse intensification) tends to produce a larger change in temperature near the poles than in the planetary average. [1] This is commonly referred to as the ratio of polar warming to tropical warming.
While the name for this phenomenon may sound intimidating to some, the polar vortex is actually a completely natural process t. Skip to main content. 24/7 help ...
The polar vortex is a gigantic, circular area of cold air high up in the atmosphere that typically spins over the North Pole (as its name suggests). What is the polar vortex? In-depth look at how ...
The wave of freezing air will serve as a harsh reminder that it's still the dead of winter despite January producing temperatures of 5-15 degrees above average across the region.
Due to climate change in the Arctic, this polar region is expected to become "profoundly different" by 2050. [1]: 2321 The speed of change is "among the highest in the world", [1]: 2321 with the rate of warming being 3-4 times faster than the global average. [2][3][4][5] This warming has already resulted in the profound Arctic sea ice decline ...
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. SSWs occur about six times per decade ...
