CL4.18

Meridional flows of heat and moisture are largely driven by global patterns of energy surplus and deficit and sensitive to multiple forcings and feedbacks. The large-scale atmospheric-oceanic circulation and the hydrological cycle are tightly intertwined with such heat and moisture transports.
For example, inter-hemispheric energy asymmetries play an important role in modulating the strength of the Hadley Circulation, which in turn modulates the low-level mass convergence and the amount of precipitation in the ITCZ and in monsoon regions. In the extra-tropics, Rossby waves affect the distribution of precipitation and eddy activity, shaping the meridional heat transport from the low latitudes towards the Poles.
We invite submissions addressing the interplay between Earth’s energy exchanges and the response of the general circulation using modeling approaches, theoretical considerations, and observations.
We also encourage contributions on dynamics, trends, characteristics and past-to-future variability of mean meridional circulation and its impact on regional climate.
