Humid subtropical climate



"A humid subtropical climate (Köppen Cfa or Cwa) is a climate zone characterized by hot, humid summers and cool winters. This climate type covers a broad category of climates, and the term "subtropical" may be a misnomer for the winter climate." [1] to find out more...

"Shanghai has a humid subtropical climate (Köppen Cfa) and experiences four distinct seasons. In winter, cold northerly winds from Siberia can cause nighttime temperatures to drop below freezing, although most years there are only one or two days of snowfall. Summer in Shanghai is hot and humid, with usually 8.7 days of the year exceeding 35 °C (95 °F). with occasional downpours or freak thunderstorms. The city is also susceptible to typhoons in summer and the beginning of autumn, none of which in recent years has caused considerable damage.[24] The most pleasant seasons are Spring, although changeable and often rainy, and Autumn, which is generally sunny and dry. The city averages 4.2 °C (39.6 °F) in January and 27.9 °C (82.2 °F) in July, for an annual mean of 16.1 °C (61.0 °F). Shanghai experiences on average 1,878 hours of sunshine per year, with the hottest temperature ever recorded at 40.2 °C (104 °F), and the lowest at −12.1 °C (10 °F).[25] The average number of rainy days is 112 per year, with the wettest month being June.[25] The average frost-free period is 276 days.[20]"[2]to find out more...

"Shanghai, located on the Yangtze River Delta on China's east coast is one of the most populous cities in both China and the world (map). Its 2009 population was estimated at 19,210,000. With its large population, Shanghai is very dense with an area of just 2,717 square miles (7,037 sq km). Because of its location on China's coast, Shanghai grew as a fishing center and port city, today however it is a center of global commerce, finance and research as well as culture and art. The city is considered one of the world's fastest growing economies. Shanghai, like both Beijing and Chongqing also has numerous historical sites. The climate of Shanghai is humid subtropical with hot, humid summers and and very cold winters." to find out more...
