November 2016 Chapter Meeting
David F. Zierden, State Climatologist of Florida
“Climate Variability and El Niño”
David Zierden began his talk by giving a little bit of background information about the Center for Ocean Atmospheric Interaction Studies at Florida State University, which is his official employer.
The talk began with a brief review of the discussions about El Niño, La Niña and the Southern Oscillation. He stressed that Southern Oscillation annual variations were the primary cause of the annual climate variability in the southeastern part of the United States. El Niño events tend to last about one year, while La Niña events are likely to last multiple years.
There was a brief discussion about how climate change will affect Southern Oscillation cycles, which led to the comments about the improvements needed in our long-range climate modeling.
