Changchun is a relatively flat terrain, which is the transition zone between the eastern mountainous area and the western Songliao Plain. With Fufeng Town-Shanghewan Line as the boundary, it is located in hilly and low mountainous areas in the southeast, with an altitude of 200-400m, and the highest peak is Laodaodong Mountain in the southeast of Shuangyang District, with an altitude of 711m. The northwest is an alluvial-diluvial platform, which belongs to the undulating terrain of high plains, with an altitude of 160-200m.
Changchun's climate is in the transitional zone between the eastern mountainous area and the semi-arid area of the western plain, belonging to the temperate continental humid climate type. Although the east and south are not far from the ocean, the role of summer monsoon is weakened due to the blocking of Changbai Mountain. The west and north are flat Songliao Plain, and the Siberian polar continental air mass is unobstructed, so the climate is generally characterized by drought and windy in spring, short and warm in summer, obvious temperature difference in autumn and long and cold in winter.
