Summer Precipitation
Anomalies During Building El Niņo Events |
 |
| There has been much speculation about whether the heavy and prolonged "monsoonal flow" precipitation early this summer into Southwest and the southern Plains has been a characteristic of the building El Niņo. Below are the precipitation anomalies for the years where the Oceanic Niņo Index was at least +0.5 for the May-Jun-Jul (MJJ) period and it was increasing, along with a composite map of all the years. Based on the composite there does not appear to me an overriding "signal". | |||||||||||||||||||||||||
