Abstract:

North China plain is a geographically significant part of China. The climate change, which created the unique climate pattern and characteristics, has a non-negligible impact on the eco-system of the countryin this area. Based on historical data (1960-2013) on daily temperature and precipitation obtained from 82 meteorological stations, together with solar activity and atmosphere environment data scattered in North China plain, this paper makes a comprehensive investigation of the patterns and features of the climate using climate tendency method, Mann-Kendall test method and cumulative anomaly method. The results reveal that the annual mean temperature varied between 11.86℃ and 14.33℃, and the temperature increased slightly with the rate of 0.23°C/10a, (P< 0.01). This ascend may be due to the rise of turbidity in the atmosphere environment, the disappearance of the 0°C isotherm, the rise of spring temperatures , and the increase of the isotherm (>15°C) area. At the same time, precipitation varied between 617.96-1060.30 mm, decreased significantly with the rate of -1.75 mm/10a,(P>0.05). The expanding of the 400-600 mm precipitation contour area, the narrowing of ranges of 600-800 mm and 800-1000 mm, and excessive reduction of autumn precipitation indicates less precipitation. And all precipitation contours showed a northward movement. The sensitive areas of characteristic climatic change were mainly located between the latitudes 35°-39°. The climate mutation, occurred during 1991-1994, has been proved have more relationship with the solar activity. The influence of solar activity on maximum temperature was bigger, and the influence of turbidity on minimum temperature was more significant. Atmosphere environmental factors of the sunshine percentage, relative humidity, and wind speed had the high correlation with the temperature change,which the average correlation coefficient was 0.74. The better climatic condition, the lower content of aerosol, and the correlation coefficient of solar radiation and annual average temperature was higher. The correlation coefficient of turbidity and annual average temperature was higher when the content of aerosol is higher. The increase of the content of aerosol caused by human activity is the main external cause to the rise of the area temperature.
