CLEX researchers find the inclusion of upper South Pacific Ocean variability significantly improved the predictions of ENSO and PDO modes in simple linear inverse models.
CLEX researchers found that applying a statistical correction to projected sea surface temperatures has a major impact on changes to rainfall with global warming, leading to a 25% reduction in future precipitation projected for the south-western Pacific.
This study evaluated GCMs for common drought metrics during the past 55 years. It found different models can produce very different simulations of drought, depending on the type of drought and metric analysed. The study points to a need to improve GCMs for droughts to reduce uncertainties in future projections.
