Paper Abstract
Based on the monthly temperature and rainfall data of 1961-2006, aridity is calculated and its multi-time scales
characteristics in different divisions in the northern slope of Tianshan Mountains have been analyzed using Mexican Hat
wavelet analysis in this article. The periodic oscillation of aridity variation and the points of abrupt change at different
time scales along the time series are discovered. Also the trend of climate change is tested. Additionally, possible
association of climate variation in this area with ENSO is explored using SOI date series. The research results indicate
that there exist obvious regional characteristics of wet-dry climate variation in the northern slope of Tianshan Mountains.
Wavelet analysis shows that there mainly exits two modes of scales (12-24 years and 4-8 years) in every division, while
catastrophe point differs in different zones. To predict on the scale of 12-24 years, it will be relatively dry in mountain
division and desert area in a period after 2006. In addition, the transition from warm-dry to warm-wet appears in oasis
area. Correlation analysis indicted that aridity variation of the northern slope of Tianshan Mountains is affected by
ENSO, while influence degree is different between areas; furthermore, this influence is one-year lagging behind ENSO
in the whole area.
