What was the weather like in Beijing on February 20 1 2004?

February 1, moderate to severe pollution, not suitable for setting off fireworks.

The highest temperature today is 6℃, and the sky may be a little gloomy. New Year's Day is the rhythm of going back to parents' home. Don't let the less bright sky affect my mood.

Compared with last year, the pollution caused by setting off fireworks on New Year's Eve this year has decreased. Yesterday, the air quality in Beijing reached moderate to severe pollution.

Today, due to the influence of low pressure and southerly wind, the diffusion conditions of pollutants are unfavorable, and the air quality is still between moderate and severe pollution, which is not suitable for setting off fireworks and firecrackers.

The fog will last until this morning, and there may be sporadic sleet in the southeast from last night to this morning. Unfortunately, this snow will not cover the earth with snow. Experts said that at present, the humidity in Beijing is enough to cope with foggy days, but it is mainly concentrated in the near-surface layer, which is not enough to bring large-scale and continuous snowfall.

Today's temperature is still not low, the highest is 6℃. Starting tomorrow, cold air will come to Beijing, and the highest temperature in Grade 4 is only about 2℃.
