Low-Frequency Variability of Surface Air Temperature in a 1000-Year Integration of a Coupled Atmosphere-Ocean-Land Surface Model

摘要: Abstract The study analyzes the variability of surface air temperature (SAT) and sea (SST) obtained from a 1000-yr integration coupled atmosphere-ocean-land model, which consists general circulation models atmosphere oceans heat water budget model land surface. It also explores role in maintaining SAT by comparing long-term with those two simpler models. They are 1 ) “mixed layer model,” that is, combined simple slab mixed ocean, 2) “fixed SST same overlying seasonally varying, prescribed SST. With exception tropical Pacific, both capable approximately simulating standard deviations observed annual 5-yr-mean anomalies local SAT. deviation tends to be larger over continents than ...
