摘要
采用Mann -Kendall方法 ,分析了郑州市南郊气象观测站近 4 0年来冬季和夏季气温突变的特点 ,并进一步分析了其与北郊城市站的温差序列的突变特点 ,结果表明 ,冬季和夏季的气温均存在突变 ,且在 2 0世纪 90年代后期冬季气温增温较快。
In the context of Mann-Kendall we investigate the characteristics of abrupt temperature change of southern suburbs meteorological station in summer and winter during 40 years, and then we also analyze the temperature range series of southern and northern suburbs.
