Geography and Climate
Physical Geography
Situated at an elevation of 1600 meters above sea level, the urban landscape is defined by its position along the banks of the Yellow River. This major waterway serves as the central geographic feature of the region, shaping the topography and providing a natural corridor through the northwestern terrain.
