Why does Bashan have more night rain, and which mountain is Bashan night rain?

Bashan, located in the Sichuan Basin, is affected by specific topographic conditions. The clouds are dense here, and during the day, under the protection of the clouds, the radiation at the bottom of the clouds and on the ground is weakened, and there is no convection into rain. At night, the upper part of the cloud layer quickly cools and the lower part is warmer, so convection occurs, forming night rain.

This situation is even more pronounced in the mountainous areas of Chongqing. Because the cold air sinks down the hillside at night, it raises the warm air and accelerates the convection, so there is more rain at night. The geographical location and mountainous terrain characteristics of Jinyun Mountain are particularly conducive to the formation of night rain.

Li Shangyin stayed here and experienced the "Bashan night rain and autumn pool".

Bashan refers to Daba Mountain, but the author's Bashan here refers to Bashan in Shushui, which refers to the Jinyun Mountain in Bashan in general, or specifically, in Bashan. This poem was written by the author while spending the night on Jinyun Mountain. Jinyun Mountain is located in Beibei District, Chongqing, and is a famous villa area in Chongqing during the Anti-Japanese War.

Bashan in the night rain of Bashan refers to Jinyun Mountain. At the junction of southern Shaanxi and northeastern Sichuan. This refers to the Bashu area.

Jinyun Mountain is located on the bank of Wentang Gorge of Jialing River in Beibei District, Chongqing, with the ancient name of Bashan. Jinyun Mountain is composed of nine peaks. The highest jade pinnacle is 1050 meters above sea level.

Known for its steepness and magnificence, Lion Peak is 980 meters above sea level. In 1982, Jinyun Mountain, North Hot Spring and Hechuan Diaoyu City were listed as national key scenic spots.

Tourist attractions: Jinyun Mountain has Asahi Peak, Xianglu Peak, Lion Peak, Juyun Peak, Ape Howling Peak, Lotus Peak, Pagoda Peak, Jade Jianfeng and Xizhao Peak 9 peaks from north to south, among which Yujian Peak is the highest, with an altitude of 1050 meters.

Night rain refers to rain that falls after 8 p.m. and before 8 a.m. the next morning. Bashan is not the Daba Mountain that most people think, which is a misunderstanding that does not understand the geography of ancient Sichuan. Cao Xuege of the Ming Dynasty wrote clearly in the "Famous Places of Interest" in Shuzhong, Jinyun Mountain in Beibei, Chongqing, was called Bashan in ancient times, and the night rain phenomenon here is particularly obvious.

Since the Northern and Southern Dynasties, it has been a famous spot here, and there are often many literati and scholars who come and go. Li Shangyin came here to play, and once stayed here temporarily and wrote this famous poem. Daba Mountain is vast and very remote, and Li Shangyin did not have any reason to stay there.

"Bashan night rain" actually refers to the mountainous areas of southwest China (including the Sichuan Basin) with many night rains. Nighttime rainfall in these places generally accounts for more than 60% of the annual precipitation. For example, Chongqing and Mount Emei accounted for 61% and 67% respectively, and Zunyi and Guiyang on the Guizhou Plateau accounted for 58% and 67% respectively.

There are also many night rains in other parts of China, but the number of night rains, the amount of night rainfall and the scope of influence are not as good as those in Daba Mountain and Sichuan Basin.

Bashan night rain rises autumn pool.

The rain at night in this part of Bashan makes the pond water level in autumn a little bit.

Bashan does not refer to a certain place exactly, but mainly refers to the southwest mountainous region of China (including the Sichuan Basin).

"Night Rain Sending North" is written by the late Tang Dynasty poet Li Shangyin.

Original text: Jun asked that the return date was not due, and the night rain in Bashan rose in the autumn pool.

He cut the candles in the west window together, but when it rained at night in Bashan.

Translation: If you ask about the return date, it is difficult to say for sure. Bashan rained heavily overnight, filling the autumn pool.

When to return, cut the candles in the west window, and tell the smell of the night rain in Bashan in person.

Summary. Bashan has many basins and is surrounded by mountains, so the relatively low terrain is high, and the temperature and air humidity are high in the low-lying places. At night, the temperature drops, and the cold air from the top of the mountain sinks, squeezing and lifting the hot and humid air in the basin, and the hot and humid air is condensed in the process of lifting and causing rain.

Why does it rain at night in Bashan.

Kiss! Hello! I'll do this for you! I'm asking Qingmu, I'm glad to serve you! Why does it rain at night in Bashan The geographical reason for the night rain in Bashan is that there is more humid air in southwest China, and the terrain is low, and it is mostly a basin terrain.

The air in the southwest of China is humid, and the humid air makes the day cloudy, the ground is not baked very hot, and the convective movement is difficult to develop; At night, the upper part of the cloud cools due to radiation, and the density is greater than that of the warm air under the cloud, and the air forms a state of heavy air at the top and light at the bottom, which promotes the development of convection and night rain.
