Monthly Temperature Outlook: November 2023
Issued: 31 Oct 2023
For November 2023, above-normal temperature is predicted over much of the ASEAN region.
For November 2023, above-normal temperature is predicted over much of the ASEAN region based on the multi-model ensemble (Figure 4), with an exception over southeastern tropical Indian Ocean where below-normal temperature is predicted. All three models agree with high confidence on above-normal temperature over most of the Maritime Continent and eastern Mainland Southeast Asia. The UK Met Office model (Figure 3) has the highest confidence of above-normal rainfall over the rest of Mainland Southeast Asia, followed by the NCEP and ECMWF models (Figures 1 and 2). All three models also predict below-normal temperature over the southeastern tropical Indian Ocean. Models’ skill is moderate to good for predicting below- and above-normal temperature over most of the ASEAN region.
