Original title: From North to South!The national cold wave process chart is here, take a look at when the get cold wave will arrive at your home
China Weather News from November 4th, my country will usher in the strongest cold wave weather process in the second half of the year. This cold wave has a wide range of impact, a long duration, and a sharp drop in temperature. There will also be strong rain and snow in some areas. Menacing. How will the cold wave affect our country? Why is this cold wave so powerful? China Weather.com has launched the “National Cold Wave Process Map” to give you a glimpse of when the strongest cold wave will affect your home.
The cold wave swept over 90% of the country, and there will be heavy wind, rain and snow cooling
As the cold wave approaches, from November 4 onwards, strong winds, rain, snow, and cooling will all come. Over 90% of my country’s land from north to south will be affected by the strongest cold wave in the second half of the year and freeze into a mass.
Judging from the national cold wave process map released by China Weather.com, the impact of the cold wave on my country officially kicked off on November 4, and will be the first to affect the northern part of Xinjiang; on November 5, it will affect most of Xinjiang and the central and western parts of the northwestern region. .
On November 6, the impact of the cold wave expanded rapidly and will advance east to south. Eastern Northwest China, North China, Northeast China, and northern Southwest China will all be affected, and the temperature will plummet.
On November 7, the cold wave will continue to move eastward and southward, covering the southern region. The chill will be felt in the eastern part of the southwestern region and most of the south of the Yangtze River.
On November 8th, the cold wave crossed the Vietnamese ridge, and even the South China region, where the cold air has always been “overwhelmed”, will feel the power of the cold wave this time.
This round of cold wave is violent, and its scope, duration, and degree of temperature reduction will crush the first cold wave in the second half of October in mid-October. It is not the same. Why is this cold wave so fierce? Hu Xiao, chief meteorological analyst of China Weather Network, analyzed that firstly, a large amount of cold air has accumulated in the Arctic; secondly, recently affected by the warm ridge of the Ural Mountains, warm air has preempted the cold air in the Arctic, causing the cold air to move southward in Western Siberia. The region continued to accumulate in large numbers, resulting in a strong force of cold air going south.
Cold wave “standby” for more than a week, the lowest temperature will be a new low in a large area
In addition to the wide range of influence, the “standby” time of this cold wave is also very long, and the impact on my country’s mainland will exceed one week. According to Hu Xiao, the reason why the “front” of the cold wave lasted was that the cold air affected our country from the westward path, starting from the north of Xinjiang and moving from the northwest to the southeast at a slower speed; the other was that the cold air moved eastward. In the process, a high-altitude trough evolved into a cold vortex, which caused its moving speed to further slow down, and it lingered for a long time in the area from Inner Mongolia to the northeast of our country. This weather situation will guide the supplementary cold air to continuously join and go south, thus lengthening this The overall impact time of the cold wave process is continuous and cold.
From the perspective of the degree of cooling, the temperature contrast before and after the impact of this cold wave is very strong. The Central Meteorological Observatory predicts that during the period of the cold wave, the temperature in most areas of my country will drop by 8~10℃, and in some areas such as Northwest, North China, Huanghuai, western Jianghuai, and southern Northeast China, the drop will reach 12~14℃, and the local drop will be 16℃. ℃ above. The reversal of cold and warm is mostly completed within 1 to 2 days, and many places will experience seasonal cooling such as “winter overnight” and “autumn the next day”. In big cities, like Urumqi, the highest temperature today is around 14°C, and tomorrow it will plummet to about -5°C, with a drop of 19°C in a single day, as if suddenly falling into an “ice cave”!
In addition, from this weekend to the beginning of next week, the lowest temperatures in many parts of the central and eastern regions will continue to set new lows in the second half of the year. The lowest temperatures in most of the north will drop below 0°C, and the lowest temperatures in the east of Jianghuai, Jiangnan, and Southwestern regions will mostly fall to single places. However, the minimum temperature in many places in South China will drop to about 15°C.
The cold wave pushes the season to change to the north or enter winter in full
This long cold wave process will also promote changes in our country’s seasonal territory. After the cold wave, most of the northern part of our country may enter winter in an all-round way, and the traces of summer will be “hard to find” in our inland areas.
Hu Xiao reminded that the performance of this cold wave process is also more obvious in terms of rain and snow. The cold air has sufficient time to cooperate with the warm and humid air flow during the eastward movement, so the precipitation range will be very wide, and there may even be low ground. The development of the vortex system has brought rain and snow to the Northeast, North China, Huanghuai and other places in conjunction with the transportation of water vapor. ChinaWeather.com warmly reminds you that you need to pay close attention to weather forecasts and warning information, make adequate preparations for cold and warmth, and take care to prevent the adverse effects of rain and snow on traffic travel.
