近48年来邢台地区气温变化趋势分析

Analysis on Temperature Change Trend in Xingtai Area in Recent 48 Years

[目的]分析近48年来邢台地区气温变化趋势。[方法]根据邢台、南宫、沙河、内丘1963～2010年的逐年及月平均气温资料,采用年际变化平均气温折线图、趋势图以及气候变率等方法,对近48年来邢台地区的气温变化趋势进行分析。[结果]近48年邢台地区年平均气温、年平均最高气温、年平均最低气温及春、夏、秋、冬季平均气温的变化趋势均呈现出大致相同的特征,即逐年升高,体现出全球变暖的气候特征;年平均气温的升高主要源于最低气温和冬季平均气温的升高,持续的暖冬对年平均气温的升高起到了决定性的作用。[结论]该研究为气候变暖背景下邢台地区的气候变化特征提供理论依据。

[Objective] The research aimed to analyze the variation trend of temperature in Xingtai in recent 48 years.[Method] According to the yearly and monthly average temperature data in Xingtai,Nangong,Shahe and Neiqiu during 1963-2010,the change trend of temperature in Xingtai area in recent 48 years was analyzed by using the line chart and trend chart of interannual variation average temperature,climatic variability.[Result] The variation trends of annual average temperature,annual average maximum temperature,annual average minimum temperature and average temperatures in spring,summer,autumn and winter in Xingtai area in recent 48 years all presented the roughly same characteristics which rose yearly.It embodied the climatic characteristic of global warming.The rising of annual mean temperature was because that minimum temperature and winter average temperature rose.The continuous warm winter played the decisive role for the rising of annual average temperature.[Conclusion] The research provided the theoretical basis for understanding the variation characteristics of climate in Xingtai area under the climate warming background.
