DynVar Climate Change
DynVar Climate Change addresses the role of the stratosphere in controlling the tropospheric circulation response to climate change, and the implications of this for oceanic and cryospheric climate change responses. Our experience to date has shown that the stratosphere will have a relatively small direct influence on global climate sensitivity (measured formally in terms of the equilibrated response to doubled CO2); instead, the stratospheric influences here will involve links between radiative forcing and the stratosphere-troposphere circulation.
DynVar Climate Change subprojects that have been proposed to date include studies of the stratospheric influence on Southern Hemisphere annular mode responses to climate forcing and on sea-ice responses to climate change.
