*"*Understanding the Processes that Drive Surface Temperature Variability*"*

_Abstract_
In this talk I will provide highlights of two different - but 
overlapping - research topics. Both relate to the processes that drive 
surface temperature variability.

In the first part I will focus on the role of ocean dynamics in driving 
sea-surface temperature variability. The key conclusion is that ocean 
dynamics act - in the net - to damp rather than drive low-frequency SST 
variability. The upshot is that the observed decadal variability - such 
as that associated with Atlantic decadal variability and the Pacific 
Decadal Oscillation - can not be traced to ocean processes.

In the second part I will focus on changes in temperature persistence 
under climate change. Here the key finding is that temperature 
persistence is certain to change across the globe, but that the signs of 
the changes depend critically on various physical processes. I will 
argue that one key but overlooked process is the changes in radiative 
damping timescales under climate change.

_Bio_
David Thompson is Professor in the School of Environmental Sciences at 
the University of East Anglia in the UK. He retains a joint appointment 
as a Professor in the Department of Atmospheric Science at Colorado 
State University in the US. He joined CSU in 2001 and UEA in 2021. His 
research foci lie in the area of large-scale climate variability, with 
an emphasis on using observations to identify novel aspects of the 
climate system, and then using models to test hypotheses motivated by 
observations.
