Yunnan with its complicated terrain has a varied climate. It is divided, from north to south, into three climatic zones -- temperate, sub-tropical and tropical, distributed, from low to high terrain, over four regions- the low, hot river valleys ba zi (small upland plains), mountain areas, and frigid highlands, forming a peculiar "three-dimensional" climate. Yunnan's climate is characterized by small seasonal change in temperature, great difference in daytime temperature, and distinct contrast between dry and wet seasons. Its mean annual temperature increases from 7oC in the northwest to 22oC or more in the Yuanjiang River valley. It has abundant rainfall and a mean annual precipitation of 750-1,750 mm. The rainfall in the wet season of May to October accounts for 83 per cent of the annual precipitation.
