根据CWT Alert 最新报道，中国气象局预计中国东北地区包括北京、天津以及河北省部分地区发生的严重空气污染将至少可能持续至12月12日。之前曾预报由于冷空气前锋的到来，该地区的空气质量可能在12月9日就会有所改善。
北京的空气污染红色警报将至少持续至12月10日12时，这也是自2013年引入新的四级系统后，北京市政府环境监测中心第一次发布空气污染的红色警报。受红色警报影响，私家车在市区行驶将受到限制，单双号限行。所有户外建筑施工项目均被叫停。政府同时建议北京市区所有学校停课至12月10日，首都地区各工厂至少停工至12月10日。停工不太可能导致严重供应链中断，但一些对时间有特定要求的发货和订单可能延迟。
中国气象局对天津和河北省部分地区的空气污染警报仍维持在第二级橙色预警。
严重空气污染仍将持续影响上述地区的能见度。北京首都机场和其他区域机场可能发生航班中断，尤其是在夜间与凌晨空气湿度相对较高的时段。地面交通也可能发生中断，相关部门可能关闭部分地区路段，尤其是河北省和京津郊区地面交通直至空气质量得到改善。首都地区的铁路运营也可能因为能见度过低而发生延误。
中航嘉信建议在以上地区或近期有计划出行至这些地区的旅客时刻关注空气污染预警，注意个人安全，合理安排出行。
Severe air pollution in northeast China
As reported in a recent CWT Alert, The China Meteorological Administration (CMA) is forecasting that severe air pollution in northeast China including Beijing, Tianjin, and parts of Hebei Province, will likely remain in the area until at least December 12. Previous forecasts predicted that air quality would improve by December 9 due to a cold front entering the region.
Beijing will remain under a red air pollution alert until at least 1200 December 10, this is the first time the Beijing's Municipal Environmental Monitoring Center has issued a red alert for air pollution since a new, four-tiered system was introduced in 2013. Under the red alert, private vehicle use is restricted within the municipality; only vehicles with even-numbered plates may drive on even calendar days, and odd-numbered plates on odd days. All outdoor construction projects are suspended. The government has advised schools throughout the Beijing municipality to remain closed through December 10, and municipal officials have ordered thousands of factories in the capital region to cease operations through at least December 10. The closures are unlikely to lead to severe supply chain disruptions, but some time-sensitive deliveries and orders may be delayed.
The CMA is maintaining orange warnings - the second highest level - for Tianjin and parts of Hebei Province.
Severe air pollution continues significantly to reduce visibility across the region. Flight disruptions are possible at Beijing Capital International Airport (PEK) and other regional airports, especially during the overnight and early morning hours when relative humidity is high. Ground travel disruptions are also likely; officials may close roadways in some areas until air quality improves, especially in Hebei and outlying areas of Tianjin and Beijing. Rail service in capital region will likely be delayed due to the reduced visibility.
CWT China reminds travelers already in or have plans to travel to the above areas, to pay close attention to the air pollution alert. Take extra precaution to ensure personal safety and arrange travel accordingly.
