Observations of Pole-to-Pole, Stratosphere-to-Ionosphere Connection

The behavior of the Earth’s middle atmosphere and ionosphere is governed by multiple processes resulting not only from downward energy transfer Sun magnetosphere but also upward terrestrial weather. Understanding relative importance mechanisms beyond solar geomagnetic activity essential for progress in multi-day predictions atmosphere-ionosphere system. recent development research infrastructure, particularly Antarctica, allows observation new ionospheric features. Here we show first time that large disturbances observed Arctic winter polar stratosphere (20–50 km above ground at 60–90°N) during a sudden stratospheric warming event are communicated across globe cause summertime plasma over Antarctica (60–90°S). Ionospheric anomalies reach ∼100% background level days. We suggest several possible could contribute to formation upper atmospheric southern hemisphere.
