Arctic and Antarctic Oscillations Drive Winter Temperature Changes in East China
The researchers studied winter temperature changes in East China over the past 100 years using climate data. They identified four warm and cold periods, with the recent warming being part of global warming. The cooling trend in the early 20th century was regional but also linked to global warming. These changes were related to shifts in the Arctic and Antarctic Oscillations. Further research is needed to understand the exact causes of these shifts.
