"Did the Tropical Pacific Drive the World's
Warming?" R.A. Kerr, 544-545. A research news discussion of
the following two papers and two related studies published
"Simulations of Atmospheric Variability Induced by Sea
Surface Temperatures and Implications for Global Warming,"
A. Kumar (NMC, 5200 Auth Rd., Camp Springs MD 20746), A. Leetmaa,
M. Ji, 632-634. An atmospheric GCM was forced with observed
interannual changes in global sea surface temperatures for the
period 1982-93. Simulated air temperature patterns over land
areas resembled observed patterns including those associated with
El Niño events, suggesting that air-sea interactions resulting
from the recently more persistent warm oceanic conditions in the
tropics contributed to the observed global warming trend during
"Causes of Decadal Climate Variability over the North
Pacific and North America," M. Latif (M. Planck Inst.
Meteor., Bundestr. 55, D-20146 Hamburg, Ger.), T.P. Barnett,
634-637. A multidecadal simulation with a coupled
ocean-atmosphere model and observations shows that about
one-third of the low-frequency climate variability in the region
results from a cycle involving the subtropical gyre circulation
in the North Pacific and the Aleutian low-pressure system.
Results provide a basis for long-range climate forecasting over
the western U.S. at decadal time scales.
