Effects of Spring Breakup on Microscale Air Temperatures in the Mackenzie River Delta
The effects of spring breakup on microscale air temperatures in the Mackenzie River delta were investigated by means of intervention analysis. Small but statistically significant increases in temperatures were detected for some areas within the delta and appeared to be related to ice breakup events...
