But what could cause the SSW? A possible explanation comes from the following animation from the NOAA of the temperature at 50 hPa (about 20 km up in the atmosphere (red is hot, blue is cold deviations from mean temperature).
You can see that the heat emanates from Siberia (Kamchatka peninsula), where volcanoes are currently active. So possibly a volcano the other side of the world can plunge us into the freezer (and 4? of snow)?
