A paper on the relationship between climate and topography in Shanxi

Shanxi is a typical mountainous plateau covered by loess, with high terrain in the northeast and low terrain in the southwest. Most areas in China are above 1 500m above sea level, and the highest point is Dou Feng, the main peak leaf of Wutai Mountain, with an altitude of 306 1. 1m, which is the highest peak in North China and is known as the "roof of North China". The lowest point is where the Xiyang River flows into the Yellow River in Yuanqu County, with an altitude of only 180 meters. The interior of the plateau is undulating, the valleys are criss-crossed, and the landform types are complex and diverse. There are mountains, hills, terraces, plains, many mountains and few rivers. Mountains and hills account for 80. 1% of the total area of the province, while Pingchuan and river valleys account for 19.9% of the total area. Main mountain ranges in Shanxi: Taihang Mountain, Luliang Mountain, Hengshan Mountain, Wutai Mountain, Zhongtiao Mountain and Taiyue Mountain. There are Datong, Xinzhou, Taiyuan, Linfen, Yuncheng, Changzhi, Jincheng, Yangquan, Shouyang, xiang yuan and Licheng basins in Shanxi.

Shanxi is located inland on the east coast of the mid-latitude mainland. Although the eastern part of the province is only 300~500 kilometers away from the coast, the climate in the eastern part of the province is weakly influenced by the ocean, and it belongs to the temperate continental monsoon climate in terms of climate types. The north is colder because of the attack of cold air mass in Inner Mongolia in winter. In summer, the southern part of the country is relatively mild because of the moist air masses coming from the Huang-Huai-Hai Plain and the North Plain of Henan Province. The climate difference between north and south is obvious. The climate is characterized by: long winter, cold and dry; In summer, the south is long and the north is short, and the rain is concentrated; In spring, the climate is changeable and there are more sandstorms. Autumn is short and the weather is mild. The whole region is sunny and rich in heat resources; There are more disastrous weather, "nine droughts in ten years"; The temperature difference between day and night is large.
