China lies mainly in the northern temperate zone under the
influence of monsoon. From September and October to March and April next year monsoon blow
from Siberia and the Mongolia Plateau into China and decrease in force as it goes
southward, causing dry and cold winter in the country and a temperature difference of 40
degree centigrade between the north and south. The temperature in China in the winter is 5
to 18 degree centigrade lower than that in other countries on the same latitude in winter.
Monsoon blows into China from the ocean in summer, bringing with them warm and wet
currents, thus rain.
Great differences in climate are found from region to region owing to China's extensive
territory and complex topography. The northern part of Heilongjiang Province in northeast
China has no summer, Hainan Island has a long summer but no winter; the Huaihe River
valley features four distinct seasons; the western part of the Qinghai-Tibet Plateau is
covered by snow all year round; the southern part of the Yunan-Guizhou Plateau is
spring-like all the year; and the northwestern inland region sees a great drop of
temperature in the day. Annual precipitation also varies greatly from region to region; it
is as high as 1,500 millimeters along the southeastern coast. Decreasing landward, it is
less than 50 millimeters in northwest China. Please click here for current weather report,
