Are El Nino Global SSTA Patterns Changing?

Modern-day El Nino episodes have a tendency to occur while many other parts of the global oceans are also warmer than normal. This observation is a large change from the previous strong El Nino episodes of 1982-83/1997-98 when most of the oceanic heat and influence on atmospheric climate was consolidated in the tropical East Pacific. Consequently, our understanding of El Nino climate rooted in the influence on the atmosphere by the 1982-83/1997-98 warm ENSO events is different for many regions.

Polar Vortex ALSO Causes Late Winter Heavy Precipitation

An intense high level atmospheric polar vortex developed during late winter. Strong positive arctic oscillation identifies the presence of the strong polar vortex. The polar vortex pattern caused extreme temperature the past 30 days in the U.S. BUT ALSO the excessive precipitation leading to early spring flooding.

What If The El Nino Fade Continues?

If ENSO continues cooling into mid-year what would be the (ENSO) influence on Great Plains and South America precipitation pattern for February through May?

U.S. ENSO Precipitation During Winter Pre/Post 1997-98 El Nino

Continuing along the lines of using climate change as a tool to predict climate (versus just as an explanation of a recent climate extreme) lets take a look at wintertime precipitation patterns across the U.S. during El Nino since the epic 1997-98 episode as described by Dr. Olivia Kellner.
