A westward extension of the warm pool leads to a westward extension of the Walker circulation, drying eastern Africa

A. Park Williams, Chris Funk

Asymmetric response

Sarah Gille
2010 Nature Geoscience  
As a result, evaluations of future climate depend in part on understanding the processes by which the Southern Ocean mixed layer evolves over time.  ...  Every ten days each float rises to the ocean surface and collects oceanic temperature and salinity data on its way up. The data are then relayed home by satellite, before the float returns to depth.  ...
