Geography and Climate

  Jiangsu Province is located in East China and occupies the southern
  part of the North China plains and the plains of the Lower Reaches of
  the Yangtze River.

  In the eastern part of the province the coastline of the Yellow Sea
  extends as long as over 1,000 kilometres. Jiangsu Province is adjacent
  to Shanghai on the east, to Zhejiang Province on the north, to Anhui
  Province on the west and to Shandong Province on the north. It covers
  an area of more than 100,000 square kilometres, with a population of
  65,350,000. The population density comes out first in China. Most
  people are of Han Nationality and some are of Hui Nationality and Man
  Nationality. The provincial capital is Nanjing.

  Climate

  Jiangsu Province is situated in the temperate zone and subtropical
  zone, with a humid and semi-humid monsoon climate. China's dividing
  line between the temperate zone and the subtropical zone is the belt
  between the Huaihe River of Jiangsu Province and North Jiangsu
  General Irrigation Canal.
 
  The annual average temperature is 130C-160C, -20C-40C in January,
  and 260C-290C in July. The highest extreme temperature is 40.90C (in
  Zhenjiang on August 22, 1959). Nanjing area is one of the three well-
  known "furnaces" in the Yangtze River basin in the summer season of
  China. The lowest extreme temperature is -23.10C (at Qingyi Lake of
  Shuyang on February 5,1969). The frost-free period lasts about 200-240
  days.

  There is heavy precipitation in the south-eastern part and light
  precipitation in the north-western part. The annual average
  precipitation is about 800-1200 millimetres. The recorded heaviest
  precipitation of a day is 314.3 millimetres (in Dongtai City on August
  21st,1965). There is more rain when plums are ripe at the time when
  spring is changing into summer. It rains for a short time, but
  frequently. It is a common phenomenon that it is raining while the sun
  is shining. Rains of this period are generally called "plum rains". But
  on the other hand, because of damp climate and appropriate
  temperature, mould grows quickly, so this period is also called "mould
  rains". Typhoons often hit this province at the end of summer and the
  beginning of autumn.
