今年会出现极寒冷冬吗?

Group 1 - The National Oceanic Environment Forecast Center predicts a slightly warmer sea temperature in China's Bohai Sea and southern East China Sea by 0.5°C to 1°C, and in the Yellow Sea and central and northern East China Sea by 1°C to 2°C this winter [1] - Experts indicate that a weak La Niña event may form this autumn and winter, with the equatorial central and eastern Pacific expected to be in a neutral to slightly cold state [1][2] - The La Niña phenomenon is characterized by abnormally cold sea surface temperatures in the equatorial central and eastern Pacific, which can influence winter temperatures in China [2] Group 2 - The occurrence of La Niña does not necessarily equate to a colder winter in China, as winter temperatures are also influenced by the strength of the East Asian winter monsoon, Arctic sea ice, Eurasian snow cover, and natural variability in atmospheric circulation [2] - Statistical data suggests that the probability of a colder winter increases with the occurrence of La Niña events, but the impact of the expected weak La Niña this year on winter temperatures remains uncertain [2]
