How will Tianjin explosion pollutants spread? How to deal with explosives

How will Tianjin explosion pollution spread under the action of wind direction?

Li Xiaoquan said, according to the live monitoring, from 23: 00 last night to 8: 00 this morning, the west wind and southwest wind dominated Tianjin, and the wind force was 1. Under this wind, pollutants mainly spread to the east or northeast, while Beijing is located in the northwest of Tianjin, so it will not be significantly affected.

According to the Tianjin Meteorological Observatory, at 09: 00 today, the wind direction near the explosion site in Binhai New Area was southwest wind with a wind speed of 2 (3 m/s). According to the numerical simulation results, in the next 24 hours, the dominant wind direction will be south to southwest, and the pollutant diffusion direction will mainly be east to northeast, which will be beneficial to the pollutant diffusion to the ocean, and the air quality in Tianjin will not be greatly affected.

At present, the meteorological department is paying close attention to the diffusion of pollutants and its impact on other regions, and China Weather Network will continue to follow up. Remind everyone that in the event of major disasters and accidents, we must remain calm, carefully identify the source of the news, and don't believe rumors at will.

The weather forecast broke the news last night. Because there are many kinds of dangerous chemicals, it is difficult to remove them, which will have an impact on people's health. The following three pictures are the wind fields at different heights today 1 1: near the ground, 1500m, 3000m. It can be seen that the wind direction from the near surface to the altitude of 1500m is mainly easterly, and Beijing and Tianjin are not affected much, but Shandong Peninsula and Liaodong Peninsula are located in the downstream, which will be affected to some extent.

Pollutants pass through Bohai Sea and reach Shandong Peninsula and Liaodong Peninsula, which is called long-distance transportation, and will be diluted and diffused in this process. At the same time, there will be rain in North China and Bohai Sea the day after tomorrow, and there will be some subsidence.

How to deal with explosive pollutants?

@ Ping An Tianjin released a message at 5: 40 on August 13, saying that according to tianjin fire news, the dust generated after the explosion did not spread, posing little threat to nearby residents. At present, all the fire fighting forces at the scene are entering the scene of the incident and launching a general attack on the fire. Because explosives are special substances, sand burial is the best way to put out the fire.

Protecting the environment is everyone's responsibility. Puwechat Tmall imported from the United States can effectively prevent smog.
