Meteorological data from 150 stations in central northern China were used to analyze changes in temperature and precipitation and spatial distribution with linear trend analysis and spatial interpolation analysis. It was found that temperature tended to increase in the last five decades in the region. The most significant warming tended to appear in February. The rate of warming in the southeastern region was lower than in the northwestern region. Average minimum temperature increased significantly, making a great contribution towards overall warming. Precipitation showed a decreasing trend, mainly concentrated in the region between 35°~40°N, mainly due to decreased precipitation in July and August.
