According to the Beijing Meteorological Observatory forecast: It is expected that a cold air activity will affect the city in early January 2011. The average temperature in the plains of Beijing is about -5 °C (-4.4 °C per year), and the extreme minimum temperature is -10 °C; precipitation in most parts of the city is 0 mm (0.9 mm per year).
Main weather process:
January 4th: There are light snow in some areas; January 5-6: North wind around level 5.
Although most of the temperature is low, there is basically no precipitation, but most of the wheat fields have been filled with frozen water before winter, which has little effect on the safe wintering of wheat.
Recently, most of Beijing's illumination is sufficient, but the average temperature in the past is low. The extreme minimum temperature in the main producing area is -11.5 °C ~ -16.4 °C, which makes the greenhouse temperature especially low, the vegetables grow slowly, and some structures are unreasonable. It is also possible that frost damage may occur.
In the winter, the winds and winds will increase, and the protection grounds should be strengthened with windproof measures and strengthened covering and heat preservation measures to prevent possible damage and damage to the protected facilities.
