2014-15 comparison to el nino and plus enso winters

[uncle W]

the mei was 0.932 during the April/May period...that is the highest number so far for this plus enso event...The oni peaked at 0.7 and we still need another month of plus 0.5 for an official el nino event...although weak...this could be the first of two el nino years but that remains to be seen...other years that peaked in A/M are 1992-93 and 1986-87...funny 1977-78 is next to 2014-15...other factors contribute to snowfall and average temperature...2014-15 is near the top for snowfall during plus enso winters...in reality this was one of the greatest el nino winters on record...
