Refining the ENSO 2023-24 Outlook by Including Multivariate ENSO Index

The JUL/AUG multivariate ENSO index (MEI) failed to indicate evolution of an El Nino climate despite the robust oceanic El Nino presence across the equatorial East Pacific. Consequently, adjustments of the ENSO 2023-24 forecast considering MEI indicate that despite a robust warm equatorial East Pacific SSTA regime continuing to strengthen during Q4/2023, the attendant El Nino climate is likely moderate.

September 2023 Global Soil Moisture 3-Month Observation/Forecast Trend

During JUN/JUL/AUG 2023 large regions of drying soils and/or worsening drought outnumbered wet regions by approximately 15 to 4. The tendency for dryness in the northern hemisphere is linked to above normal mid-troposphere high pressure associated with large areas of anomalous warm mid-latitude oceans including marine heatwaves (MHW). In the southern hemisphere, oncoming drier soils are mostly related to a developing El Nino climate.
