Atlantic Multi-decadal oscillation & Spring/Summer U.S. Rainfall

In their infancy climate forecast models were heavily influenced by whether El Nino or La Nina were present. However, with the exception of the 2015-16 El Nino the past 20 years have produced weaker and less predictable El Nino episodes giving increased visibility (and research) to influences of other lead modes of climate variability on climate forecasts. A leading influence on U.S. precipitation is the Atlantic multidecadal oscillation bursting into its warm cycle the past 20 years. The +AMO has certainly contributed to spring/summer precipitation in the U.S. growing areas.

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.

Evolution of El Nino Modoki (followed by conventional El Nino)

A tendency toward consolidation of anomalous warmth in both the surface and subsurface equatorial Pacific Ocean near and just east of the Dateline implies El Nino Modoki may be ahead for northern hemisphere winter 2018-19. Plentiful subsurface ocean warmth (also) indicates a conventional El Nino may evolve in 2019.

CIC Research: An Increase in Climate Extremes

Well-known is the atmospheric warming of the past 2-3 decades due to rapid increase in CO2 emissions into the global atmosphere. A relatively new symptom of this warming has emerged with regularity in recent years. Frequency of climate extremes whether drought or flooding, hot or cold is increasing.
