La Nina Winter
Posted: 03 Mar 2021 05:36 AM
Even though the present La Nina state of the ENSO index is weak, this winter season has had a La
Nina feel with plenty of snow and only brief intense cold temperatures. Of course, there is no simple
and direct relationship between our actual weather and/or single season climate and the ENSO
index, but it is always fun to look for one. The featured chart presents such a comparison with the
comparison between winter season precipitation and average temperature color coded by the
November 3-month-averaged value of the Southern Oscillation Index (SOI, a part of ENSO). The
2020-2021 season value is labelled on the chart and the left two panels directly compare each
seasonal precip with SOI index. There is more noise to signal with these charts, but you are free to
generate your own comparison!
