黄河上游月径流量与海温的关系研究

Relationship between sea-surface temperature (SST) and monthly runoff of upper Yellow River

采用相关、回归分析的方法,对黄河上游月径流量与全球海温的关系进行了分析.揭示了不同海区的海温对月径流量的影响,寻找出关键区和关键时段.建立了1～12月径流量的预报方程,对其模拟和预报结果进行了分析.研究表明,海温是影响黄河上游月径流量的重要因子.

By use of the correlation and regression methods, an analysis is made of the relationship between the monthly runoff and global seasurface temperature. The influences of SST of different sea areas on the monthly runoff are revealed, and the key regions and phases are searched. Furthermore, regression equations of monthly runoff from January to December are developed, and the simulated and predicted results by the equations are analyzed. The research shows that SST is an important factor affecting the monthly runoff of the upper Yellow River.
