El Nino and La Nina
-
The latest La Nina advisory was released today by NOAA’s Climate Prediction Center. It shows that a strong La Nina signal is in place in the eastern Pacific Ocean and that the winds are now in sync with the ocean conditions. This means that La Nina is likely to continue through the winter months and…

In this blog we often talk about the impacts of El Nino and La Nina about the local climate. But the combination of the two, called ENSO for El Nino Southern Oscillation, also affects the climate across many other parts of the world, causing floods in some places and droughts in others. This article from…

With a La Nina advisory in effect, that means we can expect to see several months of La Nina conditions across the Southeast, although the strength of the signal will depend on how strong and how long the La Nina is. Here is a good general discussion on the likely climate effects from Kirk Mellish…

As expected, NOAA’s Climate Prediction Center has issued a La Nina Advisory this week to note that a La Nina has officially been observed to occur. You can find their text advisory at https://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso_advisory/ensodisc.pdf. There is a 75 percent chance that it will continue through Northern Hemisphere winter. In the Southeast, a La Nina is…

In today’s webinar (recording at https://www.youtube.com/watch?v=lWnEtfS6gVk&feature=youtu.be) on climate conditions in the ACF river basin in Georgia, Alabama, and Florida, David Zierden, the Florida State Climatologist, discussed some recent changes in the temperature profile of the Eastern Pacific Ocean. Over the last month, the ocean temperature distribution has started to look much more like a La…
