These bodies of water are a huge moisture source — especially this time of year, when the water is still relatively warm from a summer of heating. (wxshift.com)
A northern shift of the ITCZ could be the trigger of these abrupt shifts of northern hemisphere atmospheric circulation resulting in 2 - 4K changes in Greenland moisture source temperature from one year to the next. (bravenewclimate.com)
The interactive feedback between clouds and ice is probably the phenomenon that best explains the amplification of Arctic temperatures because as sea ice is removed there is a dramatic decrease in albedo and an increase in moisture source necessary for cloud formation. (pubs.geoscienceworld.org)
