The Meteorological Bureau was asked to stop the smog warning? You may have seen fake headlines.

On the evening of 65438+ 10 17, a picture of "Notice on Suspension of Smog Forecast and Warning Service" was circulated in Weibo.

The words in the picture read:

The provincial meteorological bureau, the county (city) meteorological bureau directly under the jurisdiction of the province and the provincial meteorological station eavesdropped on the telephone notice of the forecast department of China Meteorological Bureau at 20171718: 36, demanding that the smog forecast and early warning work be stopped immediately.

After receiving this notice, all units are requested to immediately stop making and publishing smog forecasting and early warning products.

When the visibility is less than 10KM, it can be predicted and warned according to the relative humidity and fog.

The signer is "Ministry of Science and Technology and Prediction".

This notice on the suspension of smog forecasting and early warning business is only an internal notice and has not been publicly released. It is because the meteorological bureau and the environmental protection department often have different situations when releasing smog information.

A number of meteorological and environmental protection system analysts said that the meteorological department will no longer issue smog warning and forecast, which means that the two departments are further clarifying the division of responsibilities to avoid misunderstandings caused by the two "early warnings" in public release.

Song Yingjie, the host of the CCTV weather forecast program, forwarded the news on the certification Weibo and commented: "I guess the two departments are discussing the new regulations and how to jointly issue the smog pollution warning to avoid the inconsistency of the previous warning levels."

Why are there two color warnings on the same day? What's the difference between these two kinds of early warning?

According to the previous report of China Weather Network, firstly, the publishing units are different. The release unit of orange warning of smog is Beijing Meteorological Observatory, and the release unit of red warning of heavy pollution is Beijing Emergency Office.

Secondly, the release process is different. The orange warning of smog is decided by the internal consultation of the Central Meteorological Observatory and released by itself; The red warning of heavy pollution was established by emergency headquarters in Beijing Environmental Protection Bureau. The Beijing Emergency Office put forward the suggestion of issuing red warning information, and then the Beijing Emergency Office issued the red warning of heavy pollution.

Publishing standards are also different. Release standard of haze orange warning (Beijing Meteorological Observatory): It is expected that one of the following situations may occur in the next 24 hours and continue or the actual situation reaches one of the following situations and may continue.

In short, the main indicators of smog warning issued by Beijing Meteorological Observatory are visibility and PM2.5 concentration. The main indicator for emergency office to issue early warning of heavy pollution is AQI. It should be noted that AQI (air quality index) includes SO2, NO2, PM 10, O? CO and other five reference standards, so the concentration of PM2.5 can not completely control the AQI index.

Because the main reference indicators for issuing the two warnings are different, there will be an orange warning and a red warning.
