Beijing began to appear snow again on the night of yesterday (12th). As of 6 o'clock today, the snowfall is generally 0.5 to 1.5 mm, and the snowfall in Haidian District is 2.5 to 4.4 mm; the average snowfall in the city is 1.3 mm, and the urban average is 2.5 mm. At 6 o'clock today, the depth of snow in central and western Beijing is 1 to 3 cm, and the depth of snow in parts of Changping and Haidian is 5 to 8 cm. In Beijing today, there is a slight snow turn in the daytime, and the north wind turns to the third or fourth level, and the temperature is minus 1 to minus 10 °C. Snowfall is beneficial to improve the surface of the wheat field, alleviate the drought in the wheat field, inhibit the evaporation of wheat fields and thicken the dry soil layer, and promote the rejuvenation of the wilt wheat seedlings. However, due to the heavy drought in the previous period, it is expected that there will be no effective precipitation and wind in the middle. Therefore, it is difficult to fundamentally relieve the drought in this snowfall, and the cooling weather is not suitable for soil irrigation. It needs to be warmed up after the snow melts in the wheat field and the surface is dry. The weather will carry out repression in a timely manner. For the plots with a dry soil layer of more than 6 cm, the “life-saving water†should be replenished in time in the afternoon when the maximum temperature exceeds 5 degrees. For the protected vegetables, because the recent light can basically meet the needs of crop growth in the protected area, and the temperature is significantly higher, it is more favorable to colonize the protected vegetables. It is expected that the temperature will remain high in the middle of the year. It is necessary to pay attention to the ventilation and temperature reduction in the afternoon high temperature period to avoid the plant growth slowing and disease occurrence caused by high temperature. According to the forecast of the Municipal Meteorological Observatory: there were two cold air activities in mid-February. The average temperature in the plain area of ​​the city is around 0 °C (normally -1 °C), and the extreme minimum temperature is -9 °C. The precipitation in most parts of the city is 0 mm and the annual precipitation is 2.3 mm.
