新乡市城区近64年气温和降水量特征分析
Analysis of the characteristics of air temperature and precipitation in near 64 years in Xinxiang
摘要
Abstract
Based on the monthly average air temperature and precipitation data of Xinxiang meteorological station in Henan province during 1951-2014,the trend analysis,mutation test and periodical analysis of the annual air temperature and precipitation were conducted by using the moving average,wavelet decomposition,moving t-test,Mann-Kendall test and Morlet wavelet transformation in order that the overall variation characteristics of air temperature and precipitation in Xinxiang could be analyzed and known.The results showed that the temperature had an obvious upward trend at the 0.01 significance level in recent 64 years;the mutation happened around 1997;the first main period was 55 years for annual mean air temperature,and the precipitation had a insignificant decrease trend but had no mutate during recent 64 years;the first main period of annual precipiration was 54 years.The annual average temperature and precipitation was almost identical in the first main period.关键词
