China is vast in territory and the climate varies greatly from north to south. With
high temperatures and rainy seasons, there is no winter in Leizhou Peninsula in
southern China, Hainan Province, Taiwan Province and southern Yunnan. There are
four distinct seasons in Middle and lower reaches of the Yangtze and Yellow River
region. Northern areas such as Heilongjiang have a cold and snowy winter. The temperature
changes significantly in vast north-west. It is cold in winter and hot in summer
with very little precipitation, dry climate.
Although the weather different from geographical conditions and seasons, there are
two main features for China climate.
1. Rainfall distribution is very uneven. Annual precipitation decreases from southeast
to northwest over the difference of 40:1.
2. The wind in summer and winter changes obviously. The cold air comes from the
high-latitude continental areas, mostly northerly wind, cold and dry. Summer winds
are mainly from the sea, mostly southerly winds, warm and humid.
