Analysis by the China Meteorological Administration’s National Climate Center shows the Zhejiang provincial capital in third place in the heat chart behind Fuzhou, the Fujian provincial capital in first place, and Chongqing. Haikou, capital of the island province of Hainan, is in fourth place.
Fuzhou experienced the most days (nearly 33) when temperatures rose above 35 C — classified as “abnormally hot” — on a yearly average from 1981 to 2010.
As of Tuesday, the city had seen 17 such days this summer, including 13 in a row, according to its meteorological bureau.
Chongqing, the second-hottest city, has had nearly 30 abnormally hot days on average each year, according to the National Climate Center.
The city’s meteorological bureau issued a heat alert on Sunday, a day before temperatures rose to nearly 42 C. The July record of more than 43 C, set in 1971, still stands.
Hangzhou’s meteorological bureau said that from the end of April until Monday this week the city experienced temperatures of more than 35 C on 15 days.
Haikou has also had more abnormally hot days this year than in 2012, Guan Menyuan, director of the city’s meteorological bureau, said.
Last year, the National Climate Center released rankings based on a heat index, combining temperature and humidity data from 1981 to 2011, to gauge how people were coping with high temperatures.
Chongqing, Fuzhou, Hangzhou and Nanchang, in Jiangxi province, topped the chart in that order.
Global warming and the urban heat island effect — where a metropolitan area is significantly warmer than its surrounding rural areas due to human activities — have contributed to hotter summers, Zhang added.
