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,5a sliding trend line,Mann-Kendall mutation test .The results showed that:nearly 54a,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.
