Original title: Ministry of Ecology and Environment: Atmospheric diffusion conditions are deviating this winter and next spring, and the situation of pollution prevention and control is severe
The Ministry of Ecology and Environment held a press conference today (29th) morning to study and judge the air pollution situation in China this autumn and winter. This winter and next spring, China’s atmospheric diffusion conditions are basically close to or slightly deviated from previous years, and the situation of air pollution prevention and control is still severe.
Introduction by the relevant person in charge of the Ministry of Ecology and Environment. In terms of sand and dust weather, the sand source area in northern Asia may show a trend of less precipitation this winter and next spring, and the overall ecological situation is deviated. It is expected that there will be a high probability of sand and dust weather this winter and next spring, and the frequency of occurrence may be more than the historical average. The possibility of strong sandstorms is relatively low.
It is expected that it may enter the La Niña state in the mid-to-late fall of this year and form a weak to moderate La Niña event in the winter. This winter, the climate may be relatively cold, and parts of our country may be affected by stronger or frequent cold air processes, which is relatively conducive to the diffusion of pollutants.
The overall deviation of atmospheric diffusion conditions in North China. From February to March 2022, the temperature is close to the annual average level or slightly higher, the precipitation is close to the annual average level or slightly higher, the near-surface relative humidity is relatively high, and the near-surface wind field has a higher probability of southerly wind than normal. The overall deviation of the diffusion conditions.
