abstract = "Beginning the 1960's, observational and modeling studies of the
ocean and atmosphere began to make clear that certain behaviors of
the coupled system might be predictable, including EI Nino (see
reviews in Mason et ai. 1999). The seasonal mean tropical
circulation may be potentially more predictable than the middle
latitude circulation as the low-frequency component of the
tropical variability is primarily forced by slowly varying
boundary conditions, such as sea surface temperature (SST), as
supported by observational and modeling work. The ability of an
atmospheric model to simulate to observed climate and its
variability varies with scale and variable, with the radiative
effects of clouds and the land-surface and sea-air interactions
remaining an area of difficulty. Given the correct SST dr ice
extent, most atmospheric G,CMs can simulate the observed large-
scale climate with better skill for some areas as compared to
another, and give a use fui indication of some of the observed
regional and global interannual climate variations and trends.
Even though the ability of a model to reproduce the observed mean
interannual variability of climate is an important aspects of its
performance, it comes the fact that the abiljty of the model to
reproduce specific time sequences of interannual variability,
either at regional or global scales, not always is forced (e.g. by
SST), and that a parI of this variability may be intemal of the
atmosphere and climate system themselves. Climate simulations
using specified SST have an extensive history (se e reviews in
Brankovic and Palmer 1998), as well as a host of papers derived
from the AMIP climate simulations (see reviews in Zwiers 1996 and
Gates et ai. 1992). The possibility that the atmosphere's internal
dynamics or slowly evolving surface properties, such as soil
moisture or snow cover may also generate potentially predictable
interannual variability of seasonal mean climate.",
