Аннотация:The skill of a newly designed global atmospheric
model of intermediate complexity – QTCM (for
quasi-equilibrium tropical circulation model) in simulating
the teleconnections is investigated. The role of the ENSO
remote forcing over the Pacific surrounding regions is emphasized
from sensitivity experiments to critical parameters
of the model. The role of the tropical intraseasonal variability
(ITV) on the simulated ENSO teleconnection pattern is estimated
using the methodology proposed by Lin et al. (2000)
allowing to damp the energy of ITV in the model. The reduction
of intraseasonal variability allows emphasizing the
forced response of the atmosphere and eases the detection of
local coupled atmosphere-ocean patterns. It was shown that
the simulated ITV has an impact on the ENSO teleconnection
pattern both in the mid-latitudes and in regions of ascending
and descending branches of Walker circulation cells in the
tropics.
