The country lies almost entirely in the temperate zone. Only Hainan Province and the southernmost portions of Yunnan and Guangdong Provinces and the Zhuang Autonomous Region of Guangi lie within the tropics. A monsoon climate is a major influence in the south. The north and west have a typical continental climate, although winters are extremely dry and summers quite rainy.
During summer, warm, moist, maritime air masses bring heavy rains to eastern China, and hot, humid, summer weather is typical. Winter offers a sharp contrast, when cold, dry Siberian air masses dominate and often reach the southern provinces. Little precipitation falls during the colder months; clear days with low humidity and low temperatures are the norm.
mostly mountains, high plateaus, deserts in west; plains, deltas, and hills in east

volcanism: China contains some historically active volcanoes including Changbaishan (also known as Baitoushan, Baegdu, or P'aektu-san), Hainan Dao, and Kunlun although most have been relatively inactive in recent centuries
