This paper analyzes the causes of winter climate characteristics in Hanzhong. What are the main terrain areas that the project of diverting Han River into Wei River passes through?

The causes of winter weather characteristics in Hanzhong are as follows: it is located on the leeward slope in winter, with prevailing downdraft and abundant sunshine; The airflow heats up in the sinking process; Located in the river valley, the terrain is low and the heat is not easy to spread; Because the Qinling Mountains block the winter wind, the wind is weak.

The main terrain areas that the project of diverting Han River into Wei River passes through are river valley (Hanjiang River Basin), mountain range (Qinling Mountain) and plain (Weihe River Plain).
