黄河源区近60 a气候变化特征及暖湿化分析
Analysis on Characteristics of Climate Change and Warm-Humid in the Source Region of the Yellow River in Recent 60 Years
摘要
Abstract
In order to reveal the characteristics and trend of climate change,the general characteristics of climate change in recent 60 years were an-alyzed with linear trend analysis,Mann-Kendall break detector and Morlet wavelet transform method based on the annual average temperature and precipitation data from 1953 to 2012 in Maduo area. The results show that the annual average temperature obviously increases with the rate of 0. 289℃/10-year,and an abrupt change from low temperature to high temperature occurs in 1997. Meanwhile,there is also increasing trend with the rate 10. 21 mm/10-year of the annual average precipitation,and the abrupt change in precipitation occurs in 2003. Morlet wavelet analysis reveals that the annual mean temperature fluctuates significantly with the interval of 15-year,6-year and 29-year,and the annual mean precipitation fluctuates with the interval of 27-year,12-year and 5-year,respectively.关键词
