Large-scale climatic influences on precipitation and discharge for a British river basin
This article aims to identify the large-scale climate variables that yield significant statistical relationships with precipitation and discharge for a British river basin (Dyfi). Ranked correlation analysis was performed between gridded ERA-40 atmospheric data and Dyfi precipitation and discharge f...

This article aims to identify the large-scale climate variables that yield significant statistical relationships with precipitation and discharge for a British river basin (Dyfi).
