>The Multivariate ENSO Index (MEI) Captures The Global Temperature Impacts Of ENSO Differently Than SST-Based Indices

>But Those Differences Are Subtle I was recently asked to comment on the Multivariate ENSO Index (MEI). (Thanks, d.) This post compares the MEI to HADSST2-based NINO3.4 SST anomalies. It also removes the linear effects of ENSO from the Global … Continue reading
