Group 1 - The article discusses the current La Niña phenomenon in the equatorial central and eastern Pacific, which is characterized by a significant and sustained cooling of sea surface temperatures [3] - La Niña events typically occur every two to seven years, but their frequency has increased in recent years, closely linked to the complex mechanisms of global warming [3] - The impact of La Niña is expected to result in reduced precipitation in southern China this winter, with more frequent cold air outbreaks leading to significant temperature fluctuations [3] Group 2 - While La Niña is associated with colder winters, it is not the direct cause of cold winter conditions; other factors such as Arctic sea ice, snow cover, and mid-to-high latitude atmospheric circulation systems also play a role [3] - Predictions indicate that regions in East and South China may experience drought conditions extending from winter into spring due to the influence of La Niña [3]
