Southeast Climate Consortium • Mission:To use advances in climate sciences, including improved capabilities to forecast seasonal climate, to provide scientifically sound information and decision support tools for agriculture, forestry, and water resources management in the Southeastern USA.
University of Georgia • Gerrit Hoogenboom • David Stooksbury • Joel Paz • Carla Roncoli • Pam Knox • Axel Garcia y Garcia • Pierre Marchant • Rabiu Olatinwo • Tomas Persson
UGA Activities • Climate • Extension and Impact Assessment • Crop modeling • Decision support tools • Water resources • Pests and diseases • Corn ethanol net energy value
2-3 months Inter-annual Decadal Climate Variability Several decades 50+ years Centuries Climate Change

El Niño-Southern Oscillation (ENSO) • El Niño is one phase of an oscillation in ocean temperatures and atmospheric pressure in the eastern Pacific Ocean that can steer weather systems in the southeastern US and elsewhere. • El Niño is considered the warm phase of the oscillation. • La Niña (sometimes known as El Viejo) is the opposite atmospheric pattern from El Niño.

ENSO Impacts in the Southeast • EL Niño • Very wet winter and spring • Greatly reduces Atlantic • hurricanes • Decreases tornadoes in • the tornado alley • La Niña • Dry Fall, Winter, and Spring • Greatly increases Atlantic • hurricanes • Increases tornadoes in • the deep south • Greatly increases wildfire • risks Neutral ENSO phase increases the risk of severe freezes by 3:1 odds.
Management Decisions • Variety selection • Planting dates • Acreage allocation • Amount and type of crop insurance • Marketing • Purchase inputs
