What kind of precipitation is moderate rain in Tomb-Sweeping Day?

Hehe, I don't think this is the topic of pottery earth science, but the topic of pottery history.

What kind of precipitation is the "rainy season" depends on the geographical location. If Xinghua Village is in Shanxi and belongs to the northern region, there should be cold air during the Qingming period, so it is cold front rainfall. If it is early summer every year, the warm and humid air from the ocean confronts the cold air from the south of the mainland, forming a famous weather system in the middle and lower reaches of the Yangtze River and Huaihe River basin-the quasi-static front stop in Jianghuai. It is an important weather system for the formation of Meiyu. Whether a quasi-static front affects the formation of rainfall or a cold front or a warm front depends on where Xinghua Village is mentioned by the author, which depends on the author's writing background.

Turning to Du Mu's life and his self-introduction, we know that he has been the secretariat of Huangzhou, Chizhou and Zhou Mu. Today, on his way from Xi 'an to Huangzhou, he passed Qiting and wrote: "There are many rains during the Qingming Festival, and pedestrians on the road are dying." Excuse me, where is the restaurant? The shepherd boy points to Xinghua Village. In fact, the Xinghua Village referred to at that time was the "Xinghua Village" in Qiting Town, Macheng City, Huanggang, for the following reasons.

1. Geographically, Qiting has always been in the main road of official traffic and is an ancient city since the Southern Dynasties. Zhang Yi, a poet in the Northern Song Dynasty, left the poem "To Yunshan near the Pavilion". The pavilion in the ancient town has always been a place where politics, economy and culture are concentrated. Now it is still guarding the Hanma Highway, at the junction of Macheng, Xinzhou (formerly Huanggang), Huangpi and Hongan counties. "Huangzhou Fuzhi" also contains: "Xinghua Village is in the pavilion, with Xinglin, Xingquan and Du Mu's family". 2. Judging from the history of brewing, Qiting has a long history of brewing. According to Macheng County Records, there is a folk song: "Li Santao Flower Shop, Li Si Xinghua Shop, there is wine at the head of the village, and there are beauties in the shop". Shortly after Du Mu wrote a poem here, Xie Wuyi, a poet of the Song Dynasty, passed by and wrote a poem entitled "Jiangchengzi" on the wall of Xinghua Village: "The flag of wine in Xinghua Village is windy. Su Shi was relegated to Huangzhou Road, passing by, and unexpectedly met his friend Chen Jichang who lived in seclusion here. Since then, he came to Xinghua Village three times to drink and write poems, especially his Biography of Fangshan Zi, which is recorded here. 3. From the background of Du Mu's poems, Du Mu was relegated from Chang 'an to Huangzhou, and the pavilion is the only place to pass. When it rains in Tomb-Sweeping Day, it naturally reveals a lot of sadness, and it is bound to drown it in wine. But if you don't know where there is wine, just ask the shepherd boy, and the shepherd boy will naturally point to Xinghua Village, a prestigious wine-producing place. The atmosphere of this poem is very consistent with the scene at that time. 4. In terms of natural climatic conditions, Xinghua Village in Juting Town, Macheng has simple folk customs and beautiful scenery, with willows and willows, peaches and apricots everywhere, small bridges and flowing water, singing and herding songs, which is particularly attractive. Here is the junction of Wu Chu and Jianghuai, and the climatic conditions have the characteristics of Jianghuai climate. "Apricot blossom and spring rain in the south of the Yangtze River" is also a portrayal here. Up to now, it's always rainy and rainy in Tomb-Sweeping Day. In Shanxi in the north, there is little rain, and spring is "spring rain is as expensive as oil", so we seldom see the rainy landscape.

So this apricot blossom village can't be in Shanxi today. Therefore, judging from the characteristics of time and rainfall, the rain here should be caused by the influence of quasi-static front.
