It's been a sting, and the pace of spring has begun to accelerate. At present, there will be 3 cold air in the next 10 days to affect our country, but the strength is not strong, and it will not be as cold as after the previous cold wave.
At present, the cold air that is affecting our country will continue to move eastward and southward today to affect the eastern part of the Yangtze River and South China, and the day after tomorrow, the temperature in South China will continue to fall, and the maximum temperature in many places will drop to less than 20, from warm to cool. At the same time, the dry and cold northerly winds will also "blow away" the higher humidity in the air in southern China, and the return to the south will gradually ease.
Taking Guangdong as an example, the relative humidity in most areas dropped to about 70% at 10 a.m. today, compared with 90% yesterday, which is already lightening. Give the cold air a little more time, and it will gradually ease back to the south
After this round of cold air, there will be cold air activities around the 7th-8th, 11th-12th, and 15th, and the temperature in the northern region will fluctuate frequently. However, it is already March, and the big cold and warm contest is gradually tilting towards warmer, and the temperature will gradually rise in fluctuations.
After entering the stunning solar term until the valley rain, the temperature seems to have entered the "fast lane" of warming, and it jumps upward. The China Weather Network took stock of meteorological big data from 1991 to 2020 and found that the temperature increased by 3 compared with the rainy period23, the temperature rise is the second highest in the spring solar terms. At this time of the year, the average temperature of 10 will quickly rise from the northern part of South China during the beginning of spring to the northern part of Hubei and the southern part of Shaanxi.
All year round, the warmth of the stinging solar term is rapidly expanding to the north, and the 10th line reaches the central part of Sichuan, northern Hubei, central Anhui, and southern Jiangsu.
From the perspective of big cities, March is also the most concentrated time for spring in the country, and 15 provincial capital-level cities such as Chengdu, Changsha, Wuhan and Hangzhou will start the process of spring one after another.
Perennial sting, vernal equinox, and Qingming are the fastest warming periods of the year. After entering the sting this year, the next weather can be said to be very appropriate, but there is a slight "deviation".
When we say "in season", we mainly refer to the weather in the north. Next, the temperature in the north will warm all the way in fluctuations, and it will be warm to an "outrageous" state.
Specifically, under the influence of cold air, 2-6 coolings will occur in Huanghuai, North China, Northeast China and other places on the 7th and 8th, accompanied by 4-5 and 7-8 gusts; Around the 11th and 12th, the north of the middle and lower reaches of the Yangtze River will cool down by 4-6 one after another, accompanied by 4-5 northerly winds and gusts of 6-7.
However, due to the overall weakness of the cold air, especially in the north, there is less precipitation and sunny weather, and the temperature will rise faster! It is expected that around the 11th, the maximum temperature in many places from southern Hebei to Huanghuai can reach about 20, which is significantly higher than that of the same period in normal years, and can generally be higher than 5 6.
For example, the maximum temperature in Shijiazhuang and Zhengzhou on the 11th is expected to reach 20+, which will not only refresh the new high temperature in the two places this year, but even higher than the temperature in many southern cities that day. For example, the highest temperature in Shanghai on the 11th was 14, and the highest temperature in Nanjing on the 11th was 19.
As mentioned above, the average temperature of 10 lines during the perennial sting will reach the central part of Sichuan, the northern part of Hubei, the central part of Anhui, and the southern part of Jiangsu, and most of the south will enter spring at this time.
But this year, there was a "deviation". Spring is still grinding in the south, and spring in many places in the North China Plain may be coming early.
One of the reasons for the slow rise in temperature in the south and the slight friction in spring is the frequent rainy weather.
From today, rain and snow are expected to decrease significantly and stop in the north, but for the south, precipitation will still be very frequent in the next seven days. It is expected that from the 9th to the 11th, there will be light to moderate rain in Jiangnan, South China and the eastern part of Southwest China, of which there will be heavy to heavy rain in the southern part of Jiangnan and South China. Around the 13th and 14th, there will also be light to moderate rain in the above areas.
