Annual and seasonal precipitation trends and their attributions in the Qinling Mountains, a climate transitional zone in China

In this study, annual and seasonal precipitation trends their connection with large-scale climate indices in the Qinling Mountains (QMs) were investigated using innovative trend analysis (ITA), based on observed monthly data between 1959 2016 from 32 meteorological stations. The results indicated a declining QMs. Seasonally, decreasing was also spring autumn, while increasing summer winter. Spring autumn precipitations significantly contributed to decline precipitation. More importantly, both low high values trend, which would have significant influence ecology livelihood Additionally, of wavelet coherence showed that is strongly associated East Asian Summer Monsoon Index (EASMI), Southern Oscillation (SOI), South (SASMI), China Sea (SCSMI), Southwest Australian Circulation (SWACI). However, its relationship North Atlantic (NAO) West African (WASMI) insignificant, seasonally, EASMI had negative effects each season. It more sensitive SOI than SWACI, SASMI strong positive winter precipitation, SCSMI negatively related This study will provide scientific basis for forecast, prevention, mitigation flood future.
