Is it cold in Hanzhong in winter?

Winter in Hanzhong is not cold. Generally, the temperature will not fall below zero. Compared with the northern foot of Qinling Mountains, it is very warm here. But because Hanzhong is south of Qinling Mountains, there is no central heating, so northerners think Hanzhong is quite cold in winter.

Hanzhong belongs to the tropical climate zone of North Asia, with Qinling Mountains in the north and Daba Mountain in the south. Cold current is not easy to invade, and humid airflow is not easy to go north. The climate is mild and humid, with a certain degree of dryness and humidity.

The geographical distribution of temperature in this area is mainly controlled by topography. The annual average temperature is 65438 04℃. The west is slightly lower than the east, and the north and south mountainous areas are lower than the flat dams and hills. The annual average temperature in Pingba area below 600 meters above sea level is14.2 ~14.6℃; The average annual temperature in areas above1000m is lower than12℃; The annual average temperature in the western valley of Jialing River is higher than 65438 03℃.

Climatic characteristics of Hanzhong

Hanzhong is located in the mid-latitude of the northern hemisphere, forming a warm and humid airflow with annual precipitation, mainly from the Bay of Bengal in the Indian Ocean, followed by the Western Pacific Ocean. In summer, under the influence of the subtropical high, the water vapor in the Bay of Bengal flows northward along the southwest monsoon in the lower part of the southwest vortex, passing through Tibet, Yunnan and northwest Sichuan, reaching over this area. The water vapor in the western Pacific enters this area with the southeast airflow at the edge of subtropical high.

Winter is controlled by the polar continental cold air mass (mainly Mongolian high pressure), and there are many northwest monsoon, which leads to cold, dry and little rain. Spring and autumn are transitional seasons, with warm and little rain in spring, cool and rainy in autumn and humid climate. Water vapor evaporated in space by ground vegetation, reservoirs, rivers and pastoral areas. Almost no participation in precipitation.

The warm and humid airflow from southwest and southeast is blocked by Bashan and Qinling Mountains, which makes this area abundant in rainfall. However, because the two mountains are located on the southwest airflow path, the convergence of the water vapor system in the middle and lower clouds, the uplift of the terrain and the vertical influence of the mountains, the water vapor in this area is unequal between the north and the south, and the precipitation distribution is very different. The average precipitation for many years is between 700 ~ 1700 mm, of which Micang Mountain in the south is the most abundant and the highest in Shaanxi.
