Based on the climatic data of 22 meteorological stations in Beijing-Tianjin-Hebei region from 1961 to 2015,by means of the climate tendency rate,Mann-Kendall mutation test,Morlet wavelet analysis,and inverse distance weighting(IDW),we systematically studied the temporal-spatial variations of climatic variables over the Beijing-Tianjin-Hebei region in the recent 55 years.The results showed that:1)In the past 55 years,the Beijing-Tianjin-Hebei region underwent an increase of temperature and a decrease of sunshine,precipitation,wind speed,and average relative humidity.2)The climatic variables all went through a sudden change in 1979-1989,and the annual precipitation went through a second sudden change in 1996.3)The climatic variables all showed a complex characteristic of coupling at multiple time scales,and their first main period scales ranged from 8 to 25 years.4)In Beijing-Tianjin-Hebei region,the average air temperature showed a decreasing trend from south to north,with the change rate peaking in the central and western area.Both precipitation and its change rate showed a decreasing trend from east to west.Sunshine hours showed an increasing trend from south to north,while its change rate showed the opposite trend.Relative humidity showed a decreasing trend from southeast to northwest,while its change rate showed a decreasing trend from southwest to northeast.The peaks of wind speed and its change rate both appeared in Zhangbei and Tanggu area.
