text: Lee et al.s controlled experiment (climate model) showed increased flow through the Indonesian Throughflow during the 2007/08 and 2008/09 La Nias. This is basically the explanation for why the ocean heat content of the Indian Ocean did not cool proportionally during those La Nias. Note, however, in Figure 3 that the ocean heat content of the Indian Ocean did drop during the 2005/06 La Nia, which seems to contradict Lee et al.s model. The Lee et al. model also did not appear to respond to the 1998-01 La Nia, while the data indicate the warming of the Indian Ocean actually began then, after a drop a few years earlier.
