From the 13th to the 16th, the strongest cold wave since this winter swept most parts of our country, and many places in the north will break the minimum temperature record, and there will also be a reversal of cold and warm weather in various parts of the south. The current round of cold wave weather process has a wide range of impacts and drastic cooling, and the risk of urban safety will continue to rise.
Temperatures in some cities are set to hit record lows
Emergency response was launched in many places
Judging from the cooling calendar released by the ** Meteorological Observatory, the minimum temperature in Beijing, Tianjin, Shijiazhuang, Lanzhou, Xining, Shenyang and other cities may hit new lows. Among them, the lowest temperature in Zhengzhou on the 17th was -16, the lowest temperature in Jinan on the 17th was -14, and the lowest temperature in Tianjin on the 17th was -14, all of which may break the record of the lowest in mid-December all year round. This strong cold spell will be followed by additional cold air, so that most of the north will remain cold until the beginning of late December.
In addition, when the strong cold wave has not yet penetrated southward, most of the south is dominated by warm and humid airflow, and on the 14th, the warmth will reach its peak, and the maximum temperature in many places in the middle and lower reaches of the Yangtze River may rise to more than 20, or even about 25, which is rare in the same period. Then on the 15th, the main force of the cold wave will arrive in the south, and most of the temperatures will drop sharply in just two or three days, which is significantly lower than the same period in normal years. The core area of cooling is mainly concentrated in the area from Guizhou to Jiangnan, and the maximum temperature may drop by about 20, and the difference between cold and warm before and after is great.
On December 12, in response to the current round of cold wave weather, the Beijing Municipal Emergency Bureau issued 6 early warning and response measures to make corresponding measures from various aspects such as public travel, safe production and operation, etc., to ensure that citizens' lives, production and operation are carried out in an orderly and safe manner.
From the 14th to the 19th, the temperature continued to drop due to the influence of cold air, and the lowest temperature in Xi'an will appear on the morning of the 17th, which will be the lowest temperature since the beginning of winter. At 17:00 on December 13, the Office of the Municipal Meteorological Disaster Emergency Command decided to start the level IV emergency response for blizzard, freezing (freezing rain) and cold wave at 17:00 on December 13.
In addition, at 10:30 on December 13, the Qinghai Provincial Meteorological Bureau decided to launch a cold wave level III emergency response, requiring the relevant internal institutions and institutions directly under the provincial bureau and the meteorological bureaus of Xining City, Haidong City, Haibei Prefecture, Haixi Prefecture, Hainan Prefecture, Huangnan Prefecture, Guoluo Prefecture and Golmud City to immediately enter the emergency response.
Before the arrival of this round of cold wave, the Hebei Provincial Emergency Management Department issued a number of emergency defense documents to deal with winter cooling, such as the "Notice on Doing a Good Job in the Prevention and Response to Low Temperature Rain, Snow and Freezing Disasters in this Winter and Next Spring" and the "Notice on Preventing and Responding to Low Temperature Rain, Snow and Freezing Disasters in Hazardous Chemical Enterprises This Winter and Next Spring". At 8 o'clock on December 13, the Hebei Provincial Meteorological Disaster Prevention Headquarters upgraded the emergency response to major meteorological disasters (blizzards) to the next level.
Affected by the cold air, there will be widespread snowfall again in Hohhot from the day of the 13th to the 14th, and the cumulative snowfall in the process can reach 5 to 10 mmAfter the snowfall, the temperature began to drop significantly on the afternoon of the 14th, and the cooling range could reach 12 to 14 from the 14th to the 16th, and the local drop could reach more than 14, and on the morning of the 16th, Wuchuan dropped to about minus 27, and the rest of the area dropped to minus 22 to minus 24. From the afternoon of the 14th to the 15th, there will be northwest winds in most parts of the city, with gusts of up to 7 or more.
