"This paper examines long-term temperature and precipitation trends in the instrumental record of the Salmon River Basin of British Columbia. The climate record of two stations in the basin, Salmon Arm and Westwold, which have operated since 1921, were analysed. Overall annual temperatures have declined at both stations, most noticeably at Salmon Arm, with most of this cooling occurring in spring and autumn. However, winter temperatures have noticeably increased in Westwold. Precipitation trends were inconsistent across the basin. Overall, Salmon Arm precipitation has increased about 15% since the 1920s, with this increase confined to the spring, summer and autumn. Conversely, overall Westwold precipitation has decreased about 10%, due mainly to drier autumns and winters"--Abstract.
