The cold air is moving south, and the rain in the south will continue until the Spring Festival. Is this rain good or bad?
As for the cold air that lasts until the Spring Festival, from a rational and objective perspective, the advantages definitely outweigh the disadvantages. Although it is helpful to alleviate the drought in some areas to a certain extent, in most areas, it is full of "fixed" conditions. Affected by a certain weak cold air, the temperature in some areas in the south has also dropped. Many netizens lamented: ?The feeling of coolness in the heart was really uncommon during the Spring Festival in the past. ?
I don’t know how many waves this sudden cold air is this winter. The visit of rain, cooling and spring thunder will, to a large extent, make the temperature during the Spring Festival in 2021 somewhat different. Compared with the temperatures around the Spring Festival in previous years, the temperature during the Spring Festival in 2021 is still higher year-on-year. According to China Weather Network on February 10, 2021, heavy rainfall areas in the south have accelerated their shift to the east. (1) Heavy rainfall areas are moving eastward at a faster pace, and temperatures are gradually rising in the south.
On January 8, 2021, with the return of cold air, precipitation across the country was mainly concentrated in Guangxi, Guangdong and other places. At the same time, some cities in the southeast also experienced moderate to heavy rains, with the heaviest rains occurring in central and southern Guangxi. Due to heavy rains in central and southern Guangxi alone, 46 stations during the Xixiang War broke the historical February rainfall record for all years in history.
As of January 10, 2021, this round of heavy rainfall has begun to stop. It began to move from Guangxi and Guangdong to the east, Jiangnan and South China. However, according to the meteorological observatory report, although heavy rainfall will come, it should not be as intense as the heavy rainfall in central and southern Guangxi. As heavy rainfall areas accelerate eastward, heavy rains may occur in areas south of the Yangtze River and South China. For dry areas in these areas, heavy rainfall will definitely alleviate the drought in the beginning of spring to a great extent.
According to the weather station, as of January 11, 2021. The heavy rainfall brought by this round of cold air moving south will come to an end, but there will still be light drizzle in parts of Jiangnan and South China. The rain scene in Jiangnan at this time is like two poems recited by the Tang Dynasty poet Han Yu General: The light rain on Tianjie Street is as moist as crisp, and the color of grass is invisible even from a distance.
Although heavy rainfall has visited most areas in the south, it still cannot stop the temperature from rising. Although the temperature at the beginning of spring in 2021 is relatively low, compared with the temperatures before and after the beginning of spring in previous years, the temperature is still higher year-on-year. Moreover, in the Northeast region south of the Yangtze River, the temperature is rising most rapidly. In most areas, the temperature should reach its peak during the Spring Festival. (2) The heavy rainfall drained away, and the southern region began to continue to heat up
Although the cold air invaded south this time, the heavy rainfall continued until the Spring Festival. However, according to the forecast of the China Meteorological Observatory, this round of heavy rainfall will stop before the Spring Festival, and then the temperature will continue to rise. If you want to comment on the heavy rainfall before the Spring Festival, is it good or bad for the southern region? From my personal point of view, it can most directly alleviate the man's drought in drought-stricken areas.
For some provinces in the south, the precipitation in January 2021 is really unsatisfactory, especially in the three provinces of Guangxi, Guangdong and Zhejiang. The precipitation in January was as low as zero, and Guangdong and Guangzhou in January The precipitation is only 0.2 mm, which can be said to be a very representative example. Zhejiang Province even broke the January precipitation record in previous years. This lack of rain is really abnormal.
Around early February 2021, most areas south of the Yangtze River experienced widespread drought, and the degree of drought in some areas even reached moderate to severe levels. It is conceivable that the heavy rainfall before the Spring Festival has brought much hope to the dry areas in the south. What’s more, a few areas in the south have been experiencing generally little rain since the fall and winter of 2020.
Once precipitation is not sufficient, it will cause great natural interference in rice cultivation in the south. It is reported that some large and medium-sized cities in the south have experienced water supply shortages, and some cities have had to take measures to limit water supply and intermittent water supply. From this point of view, the heavy rainfall before the Spring Festival has really greatly alleviated the "disaster" in drought-stricken areas and water-stressed areas in the south. (3) The opposite is true in the north, the temperature rises first and then falls
As a child of a farmer in Hebei, I know the temperature in Hebei relatively well, and I live in the northwest of Hebei. Every year, the family relies on a few acres of almond trees, but the temperature gradually rises around the beginning of spring. Apricot flowers will bloom in full bloom around February to March, but around the Qingming Festival, the temperature will drop sharply, sometimes even to below zero. This will affect or even kill the development of early-blooming apricot flowers. From 2016 to 2020, a period of five years, the apricot flowers will always be frozen to death around the Qingming Festival.
For the north, the temperature fluctuations are particularly obvious around the Spring Festival. Especially during the period after the Spring Festival, temperatures in most areas in the north will take turns reaching new highs. Take the temperature in Shenyang City predicted by the meteorological observatory as an example. The highest temperature before and after the Spring Festival can reach 11℃. But with the arrival of a new wave of cold air, Beijing will bear the brunt of another sudden drop in temperature. Therefore, for our friends in the north, we must adjust our clothes appropriately before and after the Spring Festival to prevent the occasional cold.
