2. Terrain:

Shaanxi is a long and narrow area with high terrain in the north and low terrain in the south. There are many landforms such as plateaus, mountains, plains and basins. Qinling Mountains, as the climate dividing line between north and south of China, runs through the whole province. It is about 870 kilometers long from north to south and 200 to 500 kilometers wide from east to west. From north to south, it can be divided into three geomorphic areas: northern Shaanxi Plateau, Guanzhong Plain and Qinba Mountain. Among them, the plateau is 9.26 million hectares, the mountainous area is 74 1 10,000 hectares, and the plain is 39 1 10,000 hectares. The main mountain ranges are Qinling and Daba Mountain. Qinling Mountain has many famous peaks in Shaanxi, such as Huashan, Taibai Mountain, Zhong Nanshan and Mount Li.

3. Rivers and lakes:

North of Qinling Mountains is the Yellow River system, and its main tributaries are Kuye River, Wuding River, Yanhe River, Luohe River, Jinghe River (tributary of Weihe River) and Weihe River from north to south. South of Qinling belongs to the Yangtze River system, including Jialing River, Hanjiang River and Danjiang River.

In addition to the Yellow River flowing through the eastern part of the province, the rivers in Shaanxi mainly include Weihe River, Hanshui River, Jinghe River, Luohe River, Yanhe River, Wuding River, Jialing River, Danjiang River and Yaodong River. There are 583 rivers with a basin area of 100 square kilometers in the whole province. Weihe River is the largest tributary of the Yellow River, with a total length of 757 kilometers, and it is also the main river in the province. Originated in Bird and Rat Mountain, Weiyuan County, Gansu Province, it flows through Guanzhong Plain to Tongguan and joins the Yellow River. Hanshui River is the largest tributary of the Yangtze River, with a total length of 1.532 km. Ningqiang county, which originates from both ends of Micang Mountain in this province, flows through Qinba Mountain and joins the Yangtze River in Wuhan City, Hubei Province.

There are few lakes in Shaanxi. There are more than 300 Haizi in the sandy beach area of northern Shaanxi, with a water surface of nearly 90 square kilometers, the largest of which is Hongjiannao in Shenmu County, with an area of nearly 67 square kilometers and a water depth of 8- 10 meter.

4. Climate:

Shaanxi spans three climatic zones, and the climate between north and south is quite different. Southern Shaanxi has a tropical climate in North Asia, Guanzhong and northern Shaanxi have a warm temperate climate, and northern Shaanxi has a temperate climate along the Great Wall. Its general characteristics are: warm and dry in spring, less precipitation, rapid and unstable temperature rise, windy and dusty weather; Summer is hot and rainy, with occasional summer drought; Autumn is cool and humid, and the temperature drops rapidly; Winter is cold and dry, with low temperature and scarce rain and snow. The annual average temperature of the whole province 13.7℃ decreases from south to north and from east to west: 7℃- 12℃ in northern Shaanxi, 0/2℃-14℃ in Guanzhong, and 0/4℃ in southern Shaanxi. 65438+ 10 monthly average temperature-1℃-3.5℃, July average temperature 2 1℃-28℃, frost-free period 160-250 days, extreme minimum temperature-32.7. The annual average precipitation is 340-1240mm. There is more precipitation in the south and less precipitation in the north. Southern Shaanxi is a humid area, Guanzhong is a semi-humid area and northern Shaanxi is a semi-arid area.

So to sum up, if 12 degrees means that the temperature is still warm, if it is winter, it is very cold.
