Recently, the National Marine Environmental Forecasting Center announced that sea ice in Liaodong Bay has entered a severe ice period this winter. Due to persistent and intense cold air outbreaks, air temperatures over the bay have dropped significantly, causing seawater temperatures to fall below freezing and triggering rapid ice expansion. According to the latest monitoring data, the sea ice coverage in Liaodong Bay has reached approximately 10,000 square kilometers, with maximum ice thickness exceeding 25 centimeters. In some nearshore areas, landfast ice has already formed, posing challenges to maritime navigation, fisheries, and offshore oil and gas operations.Liaodong Bay is one of the three major bays in China’s Bohai Sea, where sea ice commonly occurs during winter, though its severity varies annually. Historically, the most severe ice conditions typically occur from mid-January to early February. This year, frequent and powerful cold surges have accelerated ice development, meeting the official criteria for a ‘severe ice period.’ Relevant authorities have activated emergency response protocols for sea ice disasters, enhanced monitoring and early warnings, and advised coastal operators to implement ice-prevention and mitigation measures to safeguard personnel and infrastructure.Experts note that while sea ice is a natural phenomenon, its impacts on coastal economic activities warrant attention, especially amid increasing extreme weather events. If no significant warming occurs in the coming days, ice conditions in Liaodong Bay may worsen further.
近日，国家海洋环境预报中心发布消息，辽东湾海冰已进入今冬的严重冰期。受持续强冷空气影响，辽东湾海域气温显著下降，海水温度降至冰点以下，导致海冰迅速扩展。截至最新监测数据，辽东湾浮冰范围已达约10,000平方公里，最大浮冰厚度超过25厘米，部分近岸区域甚至出现固定冰，对海上交通、渔业作业和油气平台运行构成一定影响。辽东湾是我国渤海三大海湾之一，冬季海冰现象较为常见，但每年冰情强度不一。根据历史资料，严重冰期通常出现在1月中下旬至2月上旬。今年由于冷空气活动频繁且强度大，冰情发展较快，已达到‘严重冰期’标准。相关部门已启动海冰灾害应急响应机制，加强冰情监测与预警，并提醒沿海作业单位采取防冰、抗冰措施，确保人员与设施安全。专家指出，虽然海冰是自然现象，但在极端天气频发背景下，其对沿海经济活动的影响不容忽视。未来几天若无明显回暖，辽东湾冰情可能进一步加剧。
