Climate Drift in the CMIP5 Models

Source: Journal of Climate:;2013:;volume( 026 ):;issue: 021:;page 8597

Author(s): Gupta, Alexander Sen; Jourdain, Nicolas C.; Brown, Jaclyn N.; Monselesan, Didier

Publisher: American Meteorological Society

Abstract: limate models often exhibit spurious long-term changes independent of either internal variability or changes to external forcing. Such changes, referred to as model ?drift,? may distort the estimate of forced change in ...

Further Insights on the Influence of the Indian Ocean Dipole on the Following Year’s ENSO from Observations and CMIP5 Models

Source: Journal of Climate:;2015:;volume( 029 ):;issue: 002:;page 637

Author(s): Jourdain, Nicolas C.; Lengaigne, Matthieu; Vialard, Jérome; Izumo, Takeshi; Gupta, Alexander Sen

Publisher: American Meteorological Society

Abstract: ecent observational studies have suggested that negative and positive Indian Ocean dipole (IOD) events (nIOD and pIOD, respectively) favor a transition toward, respectively, El Niño and La Niña events one year later. These ...

Observation-Based Estimates of Surface Cooling Inhibition by Heavy Rainfall under Tropical Cyclones

Source: Journal of Physical Oceanography:;2012:;Volume( 043 ):;issue: 001:;page 205

Author(s): Jourdain, Nicolas C.; Lengaigne, Matthieu; Vialard, Jérome; Madec, Gurvan; Menkes, Christophe E.; Vincent, Emmanuel M.; Jullien, Swen; Barnier, Bernard

Publisher: American Meteorological Society

Abstract: ropical cyclones drive intense ocean vertical mixing that explains most of the surface cooling observed in their wake (the ?cold wake?). In this paper, the authors investigate the influence of cyclonic rainfall on the cold ...

Extreme Rainfall Variability in Australia: Patterns, Drivers, and Predictability

Source: Journal of Climate:;2014:;volume( 027 ):;issue: 015:;page 6035

Author(s): King, Andrew D.; Klingaman, Nicholas P.; Alexander, Lisa V.; Donat, Markus G.; Jourdain, Nicolas C.; Maher, Penelope

Publisher: American Meteorological Society

Abstract: eading patterns of observed monthly extreme rainfall variability in Australia are examined using an empirical orthogonal teleconnection (EOT) method. Extreme rainfall variability is more closely related to mean rainfall ...

Cold Tongue and Warm Pool ENSO Events in CMIP5: Mean State and Future Projections

Source: Journal of Climate:;2014:;volume( 027 ):;issue: 008:;page 2861

Author(s): Taschetto, Andréa S.; Gupta, Alexander Sen; Jourdain, Nicolas C.; Santoso, Agus; Ummenhofer, Caroline C.; England, Matthew H.

Publisher: American Meteorological Society

Abstract: he representation of the El Niño?Southern Oscillation (ENSO) under historical forcing and future projections is analyzed in 34 models from the Coupled Model Intercomparison Project phase 5 (CMIP5). Most models realistically ...

Mesoscale Simulation of Tropical Cyclones in the South Pacific: Climatology and Interannual Variability

Source: Journal of Climate:;2010:;volume( 024 ):;issue: 001:;page 3

Author(s): Jourdain, Nicolas C.; Marchesiello, Patrick; Menkes, Christophe E.; Lefèvre, Jérome; Vincent, Emmanuel M.; Lengaigne, Matthieu; Chauvin, Fabrice

Publisher: American Meteorological Society

Abstract: The Weather Research and Forecast model at ?° resolution is used to simulate the statistics of tropical cyclone (TC) activity in the present climate of the South Pacific. In addition to the large-scale conditions, the model ...
