Observational Evidence of an Intensifying Hydrological Cycle
[1] Trends and variability in the 1964–2007 annual streamflow for 45 rivers spanning 5.2 106 km2 of northern Canada are investigated. Discharge averages 1153 km3 yr1 with a standard deviation of 71.4 km3 yr1 and coefficient of variation (CVQ) of 6.2 % over the 44-year period. A trend analysis reveal...
