Document Summary
Arctic amplification-the warming in the arctic is twice as much as the rest of the world. Quiz will cover up through climate models this map is the change in temp-1960-2009. Warming nearly everywhere, but the greatest is in the arctic. It is about twice that of the global mean warming. This is occurring in climate models, the underlying physics of it, is in some sense understood. S it takes longer for the ice to form: once the ice forms the ocean is warm so the i(cid:272)e (cid:449)o(cid:374)"t (cid:271)e as thi(cid:272)k. Arctic amplification is strongest in the inter over the ocean and in the fall. Sensible, latent and radiational heating in the fall- the air is getting colder, but the warm ocean giving sensible heating. A lot of evaporation forms a low cloud layer, as you lose long wave radiation from the earth the clouds absorb that. Also tends to heat the atmosphere and this also continues into the winter.
