• Polar vortex disrupted as major sudden stratospheric warming develops over the Arctic

    ByTeo Blašković

    Multiple atmospheric diagnostics show that a major sudden stratospheric warming is underway over the Arctic, with strong planetary wave activity, rapid polar warming, and reversal of the stratospheric jet indicating a significant disruption of the polar vortex circulation. This type of stratospheric disruption can influence atmospheric circulation patterns in the coming weeks, sometimes increasing the likelihood of cold air outbreaks across parts of North America, Europe, and Asia.

    A large marine heatwave has persisted along the U.S. West Coast since summer 2025, raising sea surface temperatures about 1.7–2.2°C (3–4°F) above average across parts of the Northeast Pacific. In a report published March 3, 2026, the National Oceanic and Atmospheric Administration (NOAA) Fisheries said this is only the third time in the observational record for the California Current ecosystem that such a large portion of coastal waters has remained anomalously warm for so long into winter without El Niño conditions.

  • Impulsive explosion produces brief ash emission at Mount Etna hours after M4.5 earthquake, Italy

    ByTeo Blašković

    An impulsive explosion from the Bocca Nuova crater at Mount Etna, Italy, generated a short-lived ash emission at 13:12 LT (12:12 UTC) on March 4, 2026. Surveillance cameras recorded the ash plume dispersing quickly toward the eastern side of the volcano. The eruption followed an earthquake swarm on Mount Etna’s southwestern flank earlier in the day, which included a notable ML4.5 earthquake.
