While the Arctic can experience ET (Tundra) zones, Antarctica’s landmass is dominated by the harsher EF (Ice Cap) designation due to its elevation and permanent ice sheet. The Antarctic Peninsula represents the most significant area of climatic transition.
Antarctica Versus Global Climate Zones: Understanding the EF and ET Zones
These areas, such as the Antarctic Peninsula, might fall into the ET category if the ice sheet retreats, featuring tundra-like conditions with a short, cool growing season. The combination of high elevation and polar latitude results in the EF classification being most pronounced here, where the air is thin and the cold is absolute, creating a stable atmospheric inversion layer.
The coastal fringes, while still polar, may exhibit characteristics of an ET zone depending on local conditions. The Arctic is an ocean surrounded by land, and its climate zones range from polar to subarctic, supporting varied ecosystems.

Climate Change and Shifting Boundaries Observed climate change is impacting the boundaries of Antarctica’s climate zone. Comparisons with Arctic Climate Zones It is helpful to compare Antarctica to the Arctic to understand its distinct climate zone.
