摘要

黄河源区的流量关系到邻近地区和下游的水资源。黄河源区流量的季内振荡(ISO)对黄河源区流量的分季节预测具有重要意义,但目前尚不清楚。在此,我们首次报道了 SRYR 地区河川流量的 30-60 天季节振荡,它受北欧亚大陆中高纬度地区大气 30-60 天季节振荡的调节。大气中的 30-60 天 ISO 是以罗斯比波列为特征的,波能向南传播到 TP 上,引起 TP 上的异常风响应。在大洋洲保护区上空的反气旋(气旋)风异常导致的异常高(低)气流,通过增强水汽发散(辐合),有利于 SRYR 对流层低层的干(湿)空气。干(湿)空气总是导致黄河强烈(微弱)的蒸发,这就造成了较晚的河谷(峰值)流量,从而导致 SRYR 河谷流量出现 30-60 天的 ISO。

Origin of the 30–60-day intraseasonal oscillation of streamflow in source region of Yellow River in China: a perspective of the atmospheric signals from mid-high latitude
Streamflow in source region of Yellow River (SRYR) matters with regard to the adjacent and downstream water resources. Intraseasonal oscillation (ISO) in the streamflow in SRYR is of great significance to the sub-seasonal prediction of streamflow in SRYR, but is unknown. Here, we first report a 30–60-day ISO in the streamflow in SRYR, which is regulated by the atmospheric 30–60-day ISO at mid-high latitude over North Eurasia. The 30–60-day ISO in atmosphere is featured by a Rossby wavetrain, and the wave energy propagates southward onto the TP, which causes anomalous wind response over TP. The leading anomalous high (low) with anti-cyclonic (cyclonic) wind anomalies over the TP favors dry (wet) air in lower troposphere in SRYR, via enhancing the water vapor divergence (convergence). Dry (wet) air always results in strong (weak) evaporation from the Yellow River, which causes the later streamflow valley (peak) and thereby the 30–60-day ISO in the streamflow in SRYR.
