All departments strengthen deployment, actively respond, and ＂protect＂ the cold wave and snowfall.

CCTV News:The Central Meteorological Observatory continued to issue six early warnings on February 21, and it is expected that the large-scale rain, snow and freezing weather in the central and eastern regions will continue on February 21 and enter the strongest period of rain and snow.

According to reports, as of noon on the 21 ST, the Central Meteorological Observatory issued six warnings for the third consecutive day, which is extremely rare in the same period. Among them, the orange warning of cold wave is the highest level, and the warning of blizzard is upgraded from the 20th to yellow. Weather such as freezing rain or ice particles may affect at least seven provinces. With the unusually strong warm and humid airflow, it is easy to induce strong convective weather such as thunderstorms and short-term heavy rainfall. This year, the blue warning of strong convective weather was released obviously early, and the subsequent cooling mainly appeared in the south.

Li Ning, a meteorologist from China Meteorological Bureau, explained that the cumulative temperature drop in some parts of southern China will reach or even exceed 20 degrees Celsius. After the temperature drop, there will be frequent rain and snow, which will lead to the continuous significant low temperature in Henan, Hubei, Hunan and other places. The main duration is from 23rd to 27th, so we should pay attention to keeping warm. In addition, the yellow warning of blizzard will continue to take effect on February 21, and some areas in Shandong, Henan and Hubei will continue to encounter heavy snowstorms. On the south side of the blizzard area, at least seven provinces from Guizhou to Jiangsu will be threatened by freezing weather, among which the freezing rain in Hubei and Hunan will last longer, so we must be vigilant.

In addition to the snowstorm and freezing weather, we can see that the weather changes very frequently in the next six days, such as Wuhan and Changsha. In the next five or six days, it will almost be rainy and snowy every day. Changsha has the longest freezing rain, and Wuhan will also have such complicated precipitation phases as freezing rain, snowfall and rainfall after heavy snowfall.

Experts said that among many forms of precipitation, ice particles and freezing rain are relatively rare, which is related to the thickness of the warm layer in the air. When ice crystals and snowflakes in the high air pass through the warm layer, they will melt. If they re-freeze before reaching the ground, they will fall to the ground as ice particles. When cold water drops at about 0 degrees meet the ground at about 0 degrees, they will quickly freeze and form freezing rain, which is the main cause.

According to the weather situation, Li Ning, a meteorologist of China Meteorological Bureau, said that freezing rain will quickly freeze after it falls to the ground, and with the freezing rain continuing, the thickness of ground ice will continue to increase, which has a greater impact on traffic. In addition to the impact on road traffic travel, it will also cause the wires to be covered with ice, so the impact of freezing rain is even greater for high-speed rail travel and air travel.

Emergency Management Department: Hubei, Henan and Anhui launched a four-level emergency response to low-temperature rain, snow and freezing disasters.

In view of the wide influence of the large-scale freezing process of rain and snow, the complex phase of rain and snow and the large area of freezing rain, the emergency management department launched a four-level emergency response to low-temperature freezing rain and snow disasters in Anhui, Henan and Hubei yesterday (20th).

On February 20th, the Office of the National Disaster Prevention, Mitigation and Relief Committee and the Emergency Management Department, together with the China Meteorological Bureau, continued to organize joint consultations, video dispatching Hebei, Shaanxi, Shanxi, Henan, Shandong, Anhui, Hubei and other provinces, and targeted deployment of prevention and response work in key areas.

At present, it is at the peak of Spring Festival travel rush’s return trip, and the risk of low-temperature rain, snow and freezing disasters is high. At 12: 00 on February 20th, the emergency management department launched a four-level emergency response for Anhui, Henan and Hubei. Relevant regions are required to pay close attention to weather changes, strengthen organizational leadership and overall coordination, give play to the leading role of disaster reduction committees or special command agencies, strengthen joint consultation, judgment and departmental coordination, strengthen emergency rescue forces and materials preset and dispatched, make all preparations for disaster relief in advance, and make every effort to deal with sudden dangers and disasters. The Office of the National Disaster Prevention, Mitigation and Relief Committee sent working groups to Henan, Anhui and Hubei to help guide the prevention and response work.
