00:43:01 Nadir Jeevanjee: Hi Sarah. Perhaps I’m reading too much into your results, but they seem to suggest a possible connection between southern ocean SST biases and double ITCZ biases, as well as a connection between southern ocean OHU under warming and the pattern effect. Could you comment on this?
00:44:36 Sarah Kang: Hi Nadir. Are you suggesting the SO SST bias would affect the SO OHU changes under warming?
00:47:54 Sarah Kang: My main talk was demonstrating the SO SST bias effect on the double ITCZ bias. At the end, I briefly showed that the same mechanism can be used to understand the inter-model spread in future climate projection. Larger SO OHU leads to the colder SO, inducing a stronger Southeastern Pacific, and a less El Niño-like warming.
00:49:32 Nadir Jeevanjee: That answers my question. Thanks.
00:55:31 Lorraine Hartmann: Robb, I wonder if you have thought about explaining the stair step structure of global mean temperature, with a peak after 1998 ENSO, the hiatus, then the peak associated with the 2015 ENSO and what looks like now another hiatus?
