In the past few days, the strongest cold wave since this winter has swept across most of the country. The widespread snowfall in the central and eastern parts brought by this cold wave reached its peak on the 14th. The cold wave brings not only heavy snowfall, but also strong cooling and freezing weather. According to the comprehensive emergency command center of the Ministry of Transport, as of 15 o'clock on the 15th, affected by the continuous impact of snowfall and icy roads, 191 highway sections in 13 provinces, autonomous regions and cities across the country, such as Hebei, Shanxi, Inner Mongolia and Liaoning, have taken closure measures. At present, the capacity and traffic volume of the national highway network have increased compared with yesterday.
The Inner Mongolia section of the Yellow River was closed for the first time, which was later than usual.
According to the latest release of the Yellow River Water Conservancy Committee of the Ministry of Water Resources, affected by the cold wave weather, at 15:30 on December 15, the Inner Mongolia section of the Yellow River was closed for the first time, and the first closure date was 12 days later than usual.
According to the monitoring of the Yellow River Water Conservancy Committee of the Ministry of Water Resources, the river section is located in the upstream of the Sanhu estuary section of the Inner Mongolia River section, with a frozen length of 4,000 meters and a flow rate of 717 cubic meters per second. According to the forecast of the meteorological department, the temperature will remain below minus 14 in the coming week, and it is expected that the high tide in the Yellow River basin will continue to develop.
Zhang Bingduo, Deputy Director of the Comprehensive and Drought Relief Division of the Flood and Drought Disaster Prevention Bureau of the Yellow River Water Conservancy Commission of the Ministry of Water Resources: As of December 14, the Ningmeng River has been flowing for 31 days, which is 18 days longer than the multi-year average. Affected by the recent strong cold wave, the cooling range in the Yellow River Basin is large, the coverage is wide, and the duration is long. We will closely monitor the weather situation and the development of the river closure.
At present, the Yellow River has entered the development stage of river closure. The Yellow River Water Conservancy Committee of the Ministry of Water Resources requires the water conservancy departments of the relevant provinces and autonomous regions along the Yellow River to strengthen emergency duty, strengthen the management of river-related projects such as pontoon bridges during the flood season, ensure the smooth flow of traffic, and be ready to deal with emergencies at any time, so as to ensure the safety of flood prevention during the river closure period.
Under the "warm winter", what is the development trend of cold wave weather?
According to the previous meteorological forecast, this year is a "warm winter". But the current round of cold wave weather is not only wide-ranging, but also relatively strong, why is this?What is the development trend of cold wave weather this winter?Let's listen to Zhou Bing, chief expert of climate services at the National Climate Center.
Zhou Bing, Chief Expert of Climate Services of the National Climate Center: Cold air and cold waves in early winter are the main weather phenomena in China, and the cooling process is the main feature. The winter temperature has obvious phased characteristics, and the intensity of cold air affecting China in December is weak, and the temperature in most parts of the country is higher than that of the same period in normal years. From January to February next year, cold air activity tends to be active, and there may be a phased strong cooling and heavy snowfall process in northern Northeast China, central and eastern Inner Mongolia, North China, northern Xinjiang, southern Qinghai, ** and other places. Periodic low temperatures, rain, snow and freezing weather may occur in central and southern China, southeast China, northern South China and southeastern Southwest China, but the possibility of low temperature rain, snow and ice disasters similar to those in early 2008 that lasted for a long time and had a wide range of impact is small.
