Abstract EN
This paper studies the stochastic dynamic variability of precipitation, for the upper, middle, and lower reaches of the Heihe River basin in Northwest China, by employing Mann-Kendall statistic, Pettitt test, and wavelet transform methods.
The possible associations with three prominent climatic patterns, El Niño-Southern Oscillation (ENSO), Artic Oscillation (AO), and Indian Ocean Dipole (IOD), are examined by using multiscale wavelet coherence method.
No significant trend is identified for the interannual precipitation variability.
However, about 2-year significant variability is detected for the lower reach of the Heihe River basin, and this dominating precipitation variability is essentially depicted by AO.
The possible influences of ENSO are exerted on long-term timescale, 8–16 years.
The obtained knowledge is helpful for the predications of extreme hydroclimatological events and better reservoir operations for regional water resources.
