Blame El Niño?
Posted: 29 May 2019 09:08 PM
Finding a scapegoat for lousy weather is always of interest. Can El Niño / La Niña be
blamed for our recent two months of cool and wet weather? The featured chart plots the
combination of Iowa areal averaged temperature and precipitation for April and May along
with the previous January's value of ENSO 3.4 index. The lag with the index is due to the
time it takes for the tele-connection to be felt in Iowa. The chart indicates that not much
correlation exists between these plotted fields, so it is tough to blame our present weather
on the weak La Niña presently existing.
