Jilin encounters persistent heavy fog, highways closed and flights delayed

China News Service, Changchun, November 14 (Reporter Guo Jia) Many places in Jilin Province once again encountered heavy fog on the 14th, with visibility less than 100 meters in some areas. Affected by this, many highways in the province have implemented traffic restrictions or closed entrance measures, and flights at Changchun Longjia International Airport have been delayed.

Yuntian, chief forecaster of the Jilin Provincial Meteorological Observatory, said that this round of heavy fog began on the 13th and is expected to last until the 15th. The heavy fog mainly affects Songyuan, Changchun, Liaoyuan, Siping, Tonghua, Baishan, Yanbian and other places. The visibility is about 500 meters in some areas and less than 100 meters in some places. The Jilin Provincial Meteorological Observatory issued an orange fog warning signal for the above-mentioned areas.

Heavy foggy weather has a significant impact on transportation. Data from the Jilin Provincial Transportation Department shows that as of 7:30 on the 14th, of the 258 highway toll stations in the province, 20 have implemented traffic restrictions and 141 have closed their entrances.

Affected by heavy fog, Changchun Longjia International Airport had many flights canceled on the evening of the 13th. On the 14th, the airport planned to execute 271 flights. As of about 8 o'clock that day, the visibility at the airport was still less than 100 meters, and it was not qualified for aircraft takeoff and landing. Several flights had been canceled, and the work of making up and adjusting the relevant inbound and outbound flights was in progress.

Talking about the reasons for the persistence of heavy fog, Yuntian said that the temperature in Jilin Province has picked up significantly recently, with the highest temperature rising to above 10°C, and there is sufficient water vapor in the air. At the same time, the atmospheric circulation is stable, the wind near the ground is weak, and the air flow is slow, which is not conducive to the diffusion of water vapor. The fog continues to accumulate, forming a long-term foggy weather.

This weather process is also accompanied by haze, and the superposition of fog and haze further reduces local visibility. Yuntian said that in the next 24 hours, the heavy fog in various places will gradually weaken to light fog, and is expected to intensify again in the evening. This weather process will not end until a cold air arrives on the 15th. (over)
