Zhihong Jiang, Nanjing Institute of Meteorology, Nanjing, Jiangsu, China
Detail investigation is carried out in terms of monthly average mean-, maximum- and minimum- temperature series from 1880-1992 in Shanghai. Results indicate that minimum- and mean-temperature have noticeable increasing trend, especially for the former, a phenomenon that suggests that the trend of former is more affected by enhanced greenhouse effect. However, maximum temperature was of remarkable inflexion trend in the mid to late 1940s. Besides, abrupt warming was found in 1910s, 1930s, and the early of 1980s, of which the first two occurred in daytime, only the last mainly happened in nighttime, a fact which is contribute to further research on the warming in Shanghai, China or a global basis.
