今冬极端天气发生概率增大

Group 1 - The La Niña phenomenon is characterized by a significant and sustained cooling of sea surface temperatures in the central and eastern equatorial Pacific, which can lead to various climate impacts [3] - The current La Niña state is expected to last until early 2026, but it is unlikely to develop into a La Niña event due to its duration being less than five months [3] - The average precipitation in Liaoning since the beginning of winter is 2.0 mm, which is 60% lower than the normal level, while the average temperature is -5.7°C, slightly lower than the historical average [3] Group 2 - La Niña years typically result in lower temperatures and increased precipitation in Liaoning, leading to a higher probability of extreme weather events such as cold waves and heavy rainfall [5] - The agricultural sector may face challenges due to snow and low temperatures affecting facility agriculture, while the energy sector must prepare for increased heating demand and potential peak energy usage [5] - The transportation sector needs to develop emergency plans to mitigate the impacts of rain, snow, and icy conditions on road traffic [5]
