Effect of El Nino Southern Oscillation (ENSO) on British Columbia and Yukon winter weather / Bill Taylor. : En84-218/1998E-PDF

"This paper examines the influence of El Niño/Southern Oscillation (ENSO) on British Columbia and Yukon winter temperatures, total precipitation and snowfall. El Niño winters are generally warmer throughout most of British Columbia and Yukon, and less snowfall is recorded especially in southern British Columbia. La Niña winters show the opposite, with cooler conditions for most parts of the region and greater than normal snowfall in the southern half of British Columbia. The relationship between ENSO and total precipitation is weak. Climate is naturally variable, so individual El Niño or La Niña episodes may not conform to these generalized findings. The study also found that the most extreme winters (eg. wettest, warmest) on record were not necessarily associated with El Niño or La Niña events"--Abstract.
