A new wave of cold air is coming, and the northern chill shows that most temperatures will reach new lows
Recently, cold air has frequently affected our country. Yesterday, the lowest temperatures in Beijing, Xining, Shenyang, and Changchun hit record lows in the second half of this year. The temperature in Heilongjiang and other places dropped significantly. For example, the afternoon temperature in Harbin was only in single digits. It was the first time since the beginning of autumn that the whole-day temperature was less than 10°C.
Starting today, a new wave of cold air will affect our country. It is expected that from the 15th to the 19th, the temperature in northern Xinjiang, Inner Mongolia, North China, Northeast China, Huanghuai, Jianghuai, Jianghan, western and northern Jiangnan will drop by 4 to 6°C, and the local drop can reach more than 8°C.
Today's maximum temperature line of 25℃ is still located in central Shanxi and central Hebei, and will retreat south to the Yangtze River around the 19th. By the 20th, the maximum temperature in most of the north will be less than 20°C, and the maximum temperature in many places in the northwest, northern North China, and northeastern regions will be less than 10°C. Temperatures in the north will hit new lows in the second half of the year in large areas. The highest temperatures in Hohhot, Urumqi, and Xining will drop to 10°C or below for the first time in the second half of this year.
The minimum temperature will also gradually drop, and the cold will become more obvious in the north. By around the 19th, the minimum temperature line of 10℃ will press southward to the Huanghuai River, and the 0℃ line will reach northern North China and the central part of Northwest China. In big cities, the minimum temperature in Hohhot, Xining, Yinchuan and Urumqi will drop to freezing point or below. By then, more places in the north will enter meteorological winter.
For Jiangnan and South China, the cold air will penetrate southward today, and the range above 30℃ will shrink to the southern part of Jiangnan and South China. But starting tomorrow, the subtropical high pressure will move northward strongly, and the range above 30℃ will expand northward again. The rare warmth will continue during the same period.
Heavy rainfall continues in the south, and the north will receive rare heavy rainfall during the same period
Under the intersection of cold and warm air, rainfall in the south increased significantly yesterday. Live monitoring showed that heavy rain or torrential rain occurred in some areas of Hunan and other places, and Yiyang suffered heavy rainstorms locally.
Today, rainfall continues in the south, and the heavy rainfall area will shift eastward. It is expected that there will be moderate to heavy snow or sleet in parts of northern Xinjiang, northern Xinjiang, along the Tianshan Mountains and high-altitude mountainous areas in western southern Xinjiang, and in western and central Qinghai. Among them, there will be heavy snowfall in parts of the Altay Mountains in northern Xinjiang and high-altitude areas along the Tianshan Mountains. There are moderate to heavy rains in parts of northeastern Guizhou, southern and eastern Hubei, central and northern Hunan, northern Jiangxi, and southwestern Anhui. Among them, there are heavy rains in parts of eastern Hubei, central and northern Hunan, northern Jiangxi, and southwestern Anhui.
Starting tomorrow, as the subtropical high pressure strengthens again, the warm and humid air flow will significantly strengthen and move northward. At the same time, a new round of cold air will move eastward and southward. Precipitation will increase and intensify north of the Yangtze River. The north will receive rare heavy rainfall during the same period. It is expected that there will be light to moderate snow or sleet in some areas in the mountainous areas of southern Xinjiang, Qinghai, Hexi in Gansu, northern and eastern Tibet, and heavy snow in some areas in central and eastern Qinghai. There are moderate to heavy rains in parts of the Hetao area of Inner Mongolia, eastern Northwest China, central and southern North China, Huanghuai, northern Jianghan, and northeastern Sichuan Basin. Among them, there are heavy rains in parts of eastern Gansu, northern and southwestern Shaanxi, central and southern Henan, northeastern Sichuan, and northern Chongqing.
The day after tomorrow, there will be moderate to heavy snow or sleet in some areas in northeastern Inner Mongolia and northwest Heilongjiang, and there will be blizzard or heavy snowstorm in some areas. There are moderate to heavy rains in parts of eastern Inner Mongolia, central and southern Northeast China, North China, Huanghuai, Jianghuai, Jianghan, and northwest Jiangnan. Among them, there are heavy rains or heavy rains in parts of central and southern Shandong, eastern Henan, northern Jiangsu, eastern Hebei, and central and southern Liaoning.
The scope of influence, cumulative precipitation amount and single-day precipitation intensity of this round of precipitation may be rare in the same period. The precipitation will help alleviate the meteorological drought in Shandong and Jiangsu, but we must also pay attention to the possible adverse effects on traffic such as reduced visibility and slippery roads caused by precipitation.
