The Central Meteorological Observatory is expected to have a wide range of rain and snow weather from the eastern part of the northwestern region to the south of the Huaihe River to the northern part of southern China from January 26th to 28th. Among them, the eastern part of the Qinghai-Tibet Plateau, the eastern part of the northwestern region, the western part of North China, the southern part of Huanghuai, the Jianghuai, Jianghan, the southern part of the Yangtze River, and the northern part of South China will have obvious rain and snow. Most of the above areas will have small to medium rain or sleet. Among them, Guizhou, Chongqing, western and northern Hunan, southern Hubei, central and southern Anhui, central and southern Jiangsu, northern Zhejiang and other places have heavy snow (5 to 9 mm), and there will be heavy snow in southern Anhui and southern Jiangsu. ~16 mm); during the period, there will be freezing rain in parts of western Guizhou and northeast Yunnan. On the 29th, the rain and snow in the south will be significantly weakened.
There will be weak precipitation in the meteorological arid regions of North China and Huanghuai. From the night of the 26th to the 28th, there was a weak precipitation process in parts of western North China and southern Huanghuai. It is beneficial to alleviate the drought in these places.
From the 26th to the 28th, parts of northern Xinjiang, the Qinghai-Tibet Plateau, the southeastern part of the northwestern region, the south of the Yangtze River, the northern part of South China, and the southwestern region will cool down by 4 to 6 Â°C, and the local area will reach 8 to 10 Â°C. On the 30th, temperatures in the southern region will start to rise.
The rain and snow intensity will be less than the southern rain and snow weather from January 16 to 21, and the duration is relatively short. However, due to the strong local precipitation intensity, and the Spring Festival approaching, passenger transportation, coal, electricity and oil transportation are everywhere. With the gradual peak of transportation of living materials and increased traffic pressure, the rain and snow weather will still adversely affect the transportation, mass life and material transportation of the relevant areas, especially in the eastern part of the southwest to the middle and lower reaches of the Yangtze River. At the same time, it will also have an adverse impact on the growing crops. To this end:
First, timely launch the disaster emergency plan to ensure that the Spring Festival travels in an orderly manner. Highways, railways, civil aviation and other departments should pay close attention to weather forecasting, strengthen traffic guidance and capacity allocation, launch disaster emergency plans in a timely manner, grab blocked road traffic as soon as possible, do a good job of snow removal and decommissioning, and detain passenger services to ensure safe and smooth transportation. .
The second is to coordinate the supply of urban and rural living materials and reduce the impact on the lives of the people. Low-temperature rain and snow weather will affect the transportation of materials in some areas, and relevant departments should make overall arrangements and strengthen material reserves to ensure the effective supply of production and living materials. Relevant departments also need to strengthen the inspection and maintenance of electric power and communication facilities and ice-melting work, and do a good job in maintaining the urban water supply and gas supply pipe network.
The third is to strengthen the cold and antifreeze of crops to avoid chilling and freezing damage. All localities should strengthen the cold-proof and anti-freezing work of winter crops, facility agriculture, aquatic products, etc., and the southern soil over-wet areas should pay close attention to clearing the ditch and promote crop growth.
Fourth, it is necessary to continue to do a good job in agricultural drought and mitigation in dry areas. Some areas in North China and Huanghuai will have weak precipitation, which is beneficial to improve soil moisture in these areas, but it is not enough to ease the drought. The meteorological drought will continue. It is recommended that relevant departments take measures to prevent the adverse effects of the combination of freezing and drought on agriculture.
