What 10 points must be known when the cold wave strikes at the end of the year?

When the cold wave strikes at the end of the year, we should know that the cooling range is comparable to the "overlord" cold wave in 20 16 years, and the local cooling can reach above 14℃, and the local cold in the north is "purple", so the Qinling Mountains can't stop the cold air. The lowest temperature of 0℃ will reach the northern part of South China, and the local or current temperature will break the historical period. Most cities in the central and eastern regions will usher in the coldest New Year's Day in the past eight years.

1, the cooling rate is comparable to the "overlord" cold wave of 20 16.

Sun Jun, director of the Central Meteorological Observatory, said that the cooling rate of this cold wave will be comparable to the "overlord" cold wave in 20 16. The weather process has the characteristics of wide influence range, severe cooling, low temperature and long gale duration.

2. The local temperature drop can reach above 65438 04℃.

The Central Meteorological Observatory predicts that the temperature will drop by 8 ~ 10℃ in most parts of central and eastern China from 28th to 3rd/day, and it will drop by 12 ~ 14℃ in the east of northwest China, southeast of northeast China, west and north of North China, south of Huanghuai, Jianghuai, Jiangnan and north-central South China. Most of the central and eastern regions will have northerly winds of 4-6 grades and gusts of 7-9 grades.

3, the northern part of the cold to "purple"

After cooling, the minimum temperature of -20℃ will reach central Gansu, central Ningxia, northwestern Shaanxi, central Shanxi, northern Hebei and northern Liaoning. The lowest temperature-10℃ line is from the lower reaches of the Yellow River to Qinling Mountains.

The Qinling Mountains can't stop the cold air.

Some time ago, Qinling itself blocked the cold air from boarding the hot search, but during this cold wave, the cold air was really strong and Qinling couldn't stop it. Hainan and Yunnan, which are "immune" to the cold wave all the year round, will also be affected.

The lowest temperature of 0℃ will reach the northern part of South China.

After cooling, the 0℃ minimum temperature line will be pressed south to eastern Yunnan, northern Guangxi, northern Guangdong and southern Fujian. Around 3 1, the lowest temperatures in Shanghai, Hefei, Wuhan, Nanjing and Hangzhou will all fall below-5℃; The lowest temperature in Changsha, Nanchang and Guiyang will fall below 0 C; The lowest temperatures in Guangzhou, Fuzhou, Nanning, Kunming, Chengdu and Chongqing fell below 5℃.

6. The local or current temperature has exceeded the historical period.

Sun Jun, director of the Central Meteorological Observatory, said that the cold wave was intense, and the temperature in some places may be the lowest in the same period in history. Like Beijing, it is currently estimated that the lowest night temperature in the plain area will be around-13℃ from 29th to 30th, which is close to the lowest value in the same period in the past decade.

7. Most cities in the central and eastern regions will usher in the coldest New Year's Day in the past eight years.

It is expected that most parts of the country will celebrate the New Year in sunny and cold weather this year, and most cities in the central and eastern regions will usher in the coldest New Year's Day in the past eight years. Even friends in Hainan may wear down jackets.

Specifically, the lowest temperature in Harbin on New Year's Eve is around -26℃, and the skin is exposed to frostbite, with a cold index of five stars. The temperature in Beijing is below-10℃, and the somatosensory temperature even drops to-15℃, with a cold index of four and a half stars. The temperatures in Shanghai and Hangzhou are also below freezing point, with a cold index of four stars; Chengdu, Chongqing, frozen hands and feet, cold index of three stars; Guangzhou, Shenzhen and Xiamen are obviously wet and cold, with two stars; The temperature in Sanya is also lower than normal. Friends who get half a star and are afraid of cold constitution may need a thin down jacket.

8, 65438+From February 28th to 29th, a large range of rain and snow hit.

It is estimated that from 28th to 29th, there will be snowfall, sleet or rain-to-snow in parts of eastern northwest, southern North China, Huanghuai, Jianghuai, Jianghan and other places, mainly small to medium snow, heavy snow in parts of southwestern Shaanxi, Jiangsu, Anhui, northern and western Hubei, and freezing rain in western Guizhou and eastern Yunnan.

9, will not reproduce the continuous rain, snow and freezing weather in 2008.

Sun Jun analyzed that this cold wave process will not reproduce the continuous freezing rain and snow weather in South China in 2008. From 28th to 29th, there will be a rain and snow process from southern North China to the middle and lower reaches of the Yangtze River, which will basically end on 30th. Because the intensity of cold air is relatively strong, it quickly spreads to the south. After the cold air comes down, it basically pushes the warm and humid airflow to the South China Sea. China's land is basically controlled by cold air, with less rain and snow. In 2008, there will be no continuous freezing rain and snow in the south.

10, defend well

Meteorologists reminded that since June 5438+February, the temperature in most parts of central and eastern China has been lower than normal, and the lowest temperature at 0℃ has basically reached the southernmost position since the winter of this year. In addition, due to the continuous low temperature and windy weather, the wind-cold effect in the central and eastern regions is obvious. The public should pay attention to the weather in time, take measures to prevent wind and cold, and beware of colds; It is also necessary to prevent the adverse effects of snow and ice caused by rain, snow and low temperature on travel traffic.
