abstract = "This paper presents an inter-comparison performance assessment of
the newly developed Centre for Weather Forecast and Climate
Studies (CPTEC) model (the Brazilian Atmospheric Model version
1.2, BAM-1.2) against four sub-seasonal to seasonal (S2S)
prediction project models from: Japan Meteorological Agency (JMA),
Environmental and Climate Change Canada (ECCC), European Centre
for Medium-range Weather Forecasts (ECMWF) and Australian Bureau
of Meteorology (BoM). The inter-comparison was performed using
hindcasts of weekly precipitation anomalies and the daily
evolution of Madden-Julian Oscillation (MJO) for 12 extended
austral summers (November-March, 1999/2000-2010/2011), leading to
a verification sample of 120 hindcasts. The deterministic
assessment of the prediction of precipitation anomalies revealed
ECMWF as the model presenting the highest (smallest) correlation
(root mean squared error, RMSE) values among all examined models.
JMA ranked as the second best performing model, followed by ECCC,
CPTEC and BoM. The probabilistic assessment for the event
{"}positive precipitation anomaly{"} revealed that ECMWF presented
better discrimination, reliability and resolution when compared to
CPTEC and BoM. However, these three models produced overconfident
probabilistic predictions. For MJO predictions, CPTEC crosses the
0.5 bivariate correlation threshold at around 19 days when using
the mean of 4 ensemble members, presenting similar performance to
BoM, JMA and ECCC. Overall, CPTEC proved to be competitive
compared to the S2S models investigated, but with respect to ECMWF
there is scope to improve the prediction system, likely by a
combination of including coupling to an interactive ocean,
improving resolution and model parameterization schemes, and
better methods for ensemble generation.",
