威信县近54年的气候变化特征和突变分析

The climatic variation and mutation analysis for nearly 54 years in Weixin county

  • 摘要: 利用1959—2012年威信县气象观测站年平均气温和年降水量资料,运用多年气候趋势线、5a滑动趋势线 、Mann-Kendall突变检验 、对威信县气候变化的主要特征、突变特点进行分析.结果表明:1959—2012年威信县年平均气温呈微弱升高趋势,年降水量呈明显减少趋势.年平均气温和年降水量均有明显的突变,前者突变年份在 2000年,后者突变年份较多,以1983年最显著.

     

    Abstract: Use the average temperature and annual precipitable water from 1959 to 2012 in the Weixin to get the main characteristics of climate change and the mutation characteristics analysis with the climate trend line,5a sliding trend line,Mann-Kendall mutation test .The results showed that:nearly 54a,the average annual temperature weakly increasing trend,the annual precipitation showed a decreasing trend.The annual average temperature and the average annual precipitation significantly mutation,the former mutation Year in 2000,the latter mutations more year and the 1983 is the most significant.
