摘要
利用沧州市气象台地面观测站1954～2013年逐日降水、平均气温、最低气温、最高气温等气象资料，采用周期分析、趋势分析等数理统计方法，寻找气温和降水变化规律。结果表明，沧州地区60年来气温在波动中上升，降水在波动中减少。
Based on daily precipitation, average temperature, minimum temperature, maximum temperature and other meteorological data from ground-based observatories of Cangzhou Municipal Meteorological Observatory from 1954 to 2013, the cycle analysis, trend analysis and other methods of mathematical statistics were employed to look for the changes of temperature and precipitation. The results showed that ： in the last 60 years the temperature rise in fluctuations and the precipitation reduce in fluctuations of Cangzhou.
