Year Without Winter 1877-1878
Posted: Sat Dec 24, 2016 11:18 am
There was a winter that was very warm. It occurred in 1877-1878. That winter had a strong El Nino like in 1982-1983, 1997-1998, and 2015-2016.

Minneapolis and St. Pauls had a very warm winter, along with the Midwest. For the Twin Cities, it is the warmest winter on record to this very day.
This shows that extremely strong El Nino does not lead to cold winters. Weak to moderate El Nino have produced some of the coldest winters on record.
I used this site to plot.

Turns out there is strong ridging over Hudson Bay, west of Ireland, east of Japan, and Central Siberia. There is troughing over Alaska and Texas.
This would suggest a positive East Pacific Oscillation (EPO) and West Pacific Oscillation (WPO). Positive EPO and WPO has troughing, while negative EPO and WPO have ridging. The ridging over Hudson Bay would suggest negative North Atlantic Oscillation (NAO) due to ridging. However, it is a positive NAO.
