The coldest cold wave this winter is freezing many places in China. Will it be cold this winter?

The coldest cold wave has appeared in the central and eastern regions of China since this winter. A record low temperature appeared from north to south. Low temperatures such as March 9 and April 9 occurred in many places, and the temperature reached the lowest in history. According to the statistics of China Meteorological Bureau, the cooling areas are mainly concentrated in southeastern Jilin, northwestern Shanxi, Anhui, Jiangsu and other places, and the cooling range of meteorological stations exceeds 10℃. Due to the continuous influence of the cold wave, many places will encounter strong winds, cooling and snowfall this weekend.

It snowed continuously in Yantai, the temperature once dropped to-10℃, and the beach froze. Yantai Meteorological Observatory issued yellow warning signals such as blizzard, cold wave, road icing and strong wind on the morning of 25th. In addition, there is snowfall in Weihai and other places. Sanitation workers begin to clear the snow every morning to ensure smooth traffic. The cold wave came, winter came, and the footsteps of snowflakes came to Hubei this morning. The mountains and semi-mountains in Wufeng Tujia Autonomous County, Hubei Province are covered with snow, and the fields and houses are covered with snow.

With the continuous southward movement of cold air and sufficient water vapor transported by the southern branch, rain and snow will be ushered in the southern part of North China. There will be snow or sleet in Huanghuai area of North China, northern Jiangnan, southwestern Jianghan and eastern Northwest China, and there will be light rain to moderate rain in southern Jiangnan, eastern Southwest China, western Guangdong and Hainan Island.

Although the cold wave followed this winter, many people found that the temperature would rise soon after the cold wave. The temperature in many parts of the Middle East is 2-3℃ higher than that in the whole year, and the highest temperature in Northeast China also rises above 0℃. In winter solstice, the daytime seems to be the shortest and the sunshine intensity is the lowest. Then the days began to get longer. Because the heat received by the earth is low, and the extension speed of the day is slow, the day is only extended by 1 minute/day, so the ground heat budget is still negative and continues to dissipate heat. The ground temperature continues to drop, and the temperature is getting colder and colder, and it will not reverse until after March 9. ?
