| Abstract: | Based on the air temperature data of Kaifeng National Basic Meteorological Observing Station from 1951 to 2010,using linear trend estimation,accumulative anomaly method and Yamamoto method,the characteristics and tendencies of annual temperature variation were analyzed.The results showed that:in the last 60 years,the annual average temperature in Kaifeng was in upward tendency obviously,and the average rising rate was 0.279 ℃ per 10 years,and significant at 0.05 level. |
