Biography
Jemma Jeffree is a PhD candidate in the Climate Fluid Physics group at ANU. She uses novel methods to quantify the internal variability of the climate system, in both models and observations. Mostly, her projects involve reducing large datasets to extract and synthesise useful information. Her Honours work developed a method of processing GRACE satellite gravity data to measure Antarctic Bottom Water (AABW). In previous work, she has used a conceptual model to explore decadal variability in El Niño Southern Oscillation (ENSO) within a large ensemble reanalysis. Her PhD focuses on the predictability and decadal variability of ENSO complexity using large ensembles. In particular, she is currently investigating the speed at which trivial perturbations ("butterfly wing flaps") grow to dominate the climate state.
