Abstract: Based on monthly temperature data obtained from 17 stations in the period of 1951-2016 in Henan and 14 stations in the period of 1870-1950 over central and eastern China, the annual mean temperature series of Henan province during the period of 1870-2016 were reconstructed by using multiple linear regression methods. The temporal characteristics were then analyzed by using moving linear regression and power spectrum analysis methods. The main conclusions were as follows:(1) the climate of Henan province showed a multi-decadal "cold-warm-cold-warm" pattern;(22) from 1870 onwards, the strongest warming trends at 30- and 50-year scale were observed during 1900-1929 and 1883-1932, with the linear trends amounting to (0.046±0.018)℃/a and (0.031±0.008)℃/a, respectively. The largest cooling trends for the same scales were detected for 1928-1957 and 1923-1972, with the linear trends being (-0.043±0.024)℃/a and (-0.026±0.010)℃/a, respectively. Changing rates for the late-20th century did not exceed the magnitude before; (3) during the period of 1870-2016, significant periodicity of 2~4 a and 64a were detected over Henan province. The former periodicity was probably driven by ENSO and QBO, while the latter may be influenced by PDO.
