Shanghai is the most populous city proper in the world, with a population of more than 24 million as of 2014. As one of the four direct-controlled municipalities of the People's Republic of China, it is a global financial centre and transport hub, with the world's busiest container port. Located in the Yangtze River Delta in East China, Shanghai sits on the south edge of the mouth of the Yangtze in the middle portion of the Chinese coast. The municipality borders the provinces of Jiangsu and Zhejiang to the north, south and west, and is bounded to the east by the East China Sea.
Climate
Shanghai has a humid subtropical climate and experiences four distinct seasons. Winters are chilly and damp, with north-westerly winds from Siberia can cause night-time temperatures to drop below freezing, although most years there are only one or two days of snowfall. Summers are hot and humid, with an average of 8.7 days exceeding 35 °C (95 °F) annually; occasional downpours or freak thunderstorms can be expected. The city is also susceptible to typhoons in summer and the beginning of autumn, none of which in recent years has caused considerable damage.
