Qingming is likely to rain in 2018.
Based on modern data, the precipitation times of some provincial capital cities during the Qingming Festival from 1951 to 1980 and 1981 to 2010 are analyzed. It was found that after the reform and opening up, there was less rain on Qingming Festival. In addition, there are more precipitation times in the South than in the north. Especially in the Jiangnan area represented by Changsha and Nanchang, there were more than 30 times of rain during the Qingming Festival from 1951 to 2010, that is, more than half of the Qingming Festival had rain.
Since the Tang Dynasty, it will rain in Qingming
Every time there is a tradition of rain in Qingming, it has existed in ancient times. Du Mu, a poet of the Tang Dynasty, wrote the poem "rain comes one after another during the Qingming period", which at least shows that it will rain from the beginning of the Tang Dynasty.
According to the book climate change in the past dynasties of China, during the Sui and Tang Dynasties, the eastern monsoon region of China showed the characteristics of "four wetness" and "three dryness". The four wetness periods were 590-640, 710-740, 810-820 and 880-900 A.D.
Du Mu, who was born in 803 and died in 852, was a Jinshi in Luoyang in February 828 and embarked on an official career. It can be said that when he was young, he was in a period of relatively humid climate in China. It can be inferred that he had more opportunities to experience 'rain in Qingming' from childhood. However, after he became an official, the climate in China has generally become dry.
After the founding of the people's Republic of China, there is still a lot of clear and bright rain in Jiangnan
According to the data, from 1949 to 2015, there were 41 years of Qingming Festival in Wuhan, when it rained, with a probability of more than 60%; since 2008, there has been a small and long Qingming holiday, the year in which there is no rain in three days of the holiday in Wuhan is only 2010. From the distribution of precipitation days in the first ten days of April, it is also proved that Jiangnan region loves rain most during the Qingming solar term.
However, according to the precipitation times of some provincial capital cities in 1951-1980 and 1981-2010, it is found that after the reform and opening up, the precipitation of Qingming is less, but the precipitation times in the south are generally more than that in the north.
After entering the 21st century, there are more clear and bright rain. Especially in Beijing, the precipitation frequency of Qingming Festival from 2001 to 2010 is as much as that of Hangzhou, Nanjing and Wuhan. Especially after 2010, it seems that there is still more rain on Qingming Festival.
When the warm and cold air meet, it will rain one after another
Generally speaking, the sunshine in the northern hemisphere increased significantly during the Qingming period. At this time, the subtropical high in the Western Pacific also strengthened its westward extension, and the southwest wind began to increase, bringing warm and humid air from the ocean to the south of the Yangtze River in China. However, the remaining cold air in winter is still in a corner, which results in the convergence of cold and warm air and precipitation.
Meteorological experts further explained that the folk saying goes: 'March 3, September 9, everything goes to the river. 'it means that at this time of Qingming, not only the wind is strong, but also the cold air, which makes the cold and warm air flow further converge, and Qingming rain is mainly formed by the intersection of the cold and warm air flow. In addition, most of the precipitation in Qingming is continuous, so drizzle has become a unique weather phenomenon in most cities in April.
