The main climate type in the vast area east of Xishan Mountain is temperate continental climate, especially the existence of the Central Plains, which makes cold and warm air drive in directly and intensifies the temperature annual range. The subtropical region in the southeastern United States has a humid climate, which belongs to the subtropical monsoon humid climate.
