Summary of Temperature in Beijing
Spring: the temperature rises quickly, and the temperature difference between day and night is large. The average monthly temperature can increase by 9 ℃, 4.5 ℃ in March and 13.1 ℃ in April. The temperature is high in the daytime, but the cooling is strong at night, and the temperature is low, which is the season with the biggest temperature difference between day and night. In general, the diurnal range of air temperature is 12 ℃, and the maximum diurnal range is 16.8 ℃. In addition, the cold air activity in spring is still very frequent, due to a sharp drop in temperature, the emergence of “late spring cold” weather, easy to form late frost.
Summer: except for the mountain area, the monthly average temperature in the plain area is above 24 ℃. July is the hottest month of the year, the average temperature is close to 26 ℃, the high temperature is long-lasting and stable, and the temperature difference between day and night is small.
Winter: cold and long. The winter lasts as long as 5 months, and if the average temperature below 0 ℃ is regarded as severe winter, there are 3 months (December to February). In January in the middle of winter, the average temperature in the plain is below-4 ℃, the mountain area is below-8 ℃, and the extreme minimum temperature in the plain is-27.4 ℃.

What Are the Climatic Characteristics of Beijing?
The weather and climate characteristics of Beijing is located on the east coast of Eurasia. Although the ocean is bordered by the sea to the east, the influence of the ocean on the climate of the city is mainly reflected in summer, and other seasons are mainly affected by the atmospheric circulation in the westerly zone. it is a typical warm temperate semi-humid continental climate. The geographical location and topography of Beijing determine the following characteristics of Beijing’s climate:
the precipitation is concentrated and the precipitation intensity is high. Beijing is located in the channel where the dry and cold air masses of the mainland move to the southeast, and is almost completely controlled by the dry and cold air masses from Siberia from October to May of the following year, and only affected by the warm and humid air masses of the sea for more than three months from June to September. Therefore, the precipitation is mainly concentrated in summer, especially in July and August. The precipitation varies greatly from year to year, and there is a great difference between the rainfall in the rainy year and the dry year.
the regional distribution of precipitation is uneven. The warm and moist air from the southeast is uplifted by the Yanshan and Taihang Mountains, forming a rainy area on the windward slope in front of the mountain and a less rainy area on the leeward slope.
the temperature of the Piedmont plain increased significantly. Due to the blocking of the cold air by the mountains and the effect of sinking and warming, the winter temperature in the Beijing plain is higher than that in the adjacent areas at the same latitude, forming a Piedmont warm area.
the diurnal variation of wind direction is significant.
One Day, the Air Quality Index in Northwest Beijing
According to the actual situation, the air quality index in northwest Beijing has reached 500, the air quality has “exploded”, the northern region has reached a serious to serious pollution level, and the city as a whole is at a level 4 moderate pollution level.
A client reporter from the Beijing Daily noted that at 18:00 today, the hourly PM10 concentration at the northwest Beijing station was 731 micrograms per cubic meter, and the air quality index reached the highest value of 500. In addition, Dingling Station, Changping Town Station, Miyun Station and Huairou Town Station all reached six levels of serious pollution, and the primary pollution was PM10.
The city has issued the first blue warning signal of sand dust this year. It is expected that there will be sand and dust weather in most parts of Beijing from now to the night of the 24th, please take precautions. It is expected that the foreign sand and dust will basically move out of Beijing tomorrow morning, and the air quality will improve.
