I'm not sure this is the reason for this specific observation, but one mechanism I've read of was that arctic air is very dry relative to equatorial, and any heating up increases its humidity, and in turn water vapor is a much more intense greenhouse gas than many other things, so it can cause more localized warming, which feeds a cycle. Why it isn't a complete runaway process i don't know, and I may be misremembering the details.
