Climate Variability in the Southeast NIDIS Southeast Pilot, Apalachicola Workshop Apalachicola, FL April 27, 2010 David F. Zierden Florida State Climatologist Center for Ocean Atmospheric Prediction Studies The Florida State University Seasonal Rainfall Patterns January Average Rainfall June Average Rainfall Nearly 60% of annual rainfall in west-central Florida comes in the months of June through September. Typical Recharge in North Georgia - Courtesy SERFC Response of Hydrologic Systems Apalachicola at Chattahoochee Georgia Annual Rainfall The El Nio /La Nia Cycle The El Nio /La Nia cycle is the predominant mode of year to year climate variability in the Southeast. Winter Jet Stream Patterns El Nio La Nia El Nio Effects on Precipitation La Nia Effects on Precipitation ENSO and Flow Rates Apalachicola at Chattahoochee Probabilistic Nature of Forecasts March - El Nio March - La Nia Normal 5.1 in. Tracking Tracking the El Nio /La Nia Cycle Sea surface temperature anomalies averaged over the Nino 3.4 portion of the equatorial Pacific Ocean Smoothed with a three-month running average to reduce noise Current Conditions - Current Conditions - El Nio is here!
