There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Quantifying Air-sea Interactions in the Tropics
It has been long recognized that the atmosphere and ocean interact in a two-way fashion: while variations in the ocean surface drive changes in the atmosphere, atmospheric variability also originates from atmospheric intrinsic dynamics, which acts as a stochastic forcing of the ocean. The two components are inherently mixed in nature, and as a result, neither process can be easily understood from a coupled atmosphere-ocean system. This has created a challenge in interpreting the observed air-sea relationships and in simulating air-sea interactions in climate models.
Here, I will show that the ocean induced and atmospheric intrinsic variability can be cleanly dissected with targeted uncoupled atmosphere-only simulations. This uncoupled framework provides an ideal tool for developing a process-based understanding of tropical air-sea interactions and for diagnosing model biases. I will use the uncoupled framework to shed light on some important aspects of tropical convection and its interaction with the SST. I will show that convection sensitivity to SST variability is predominantly determined by the local climatological SST and that this relationship is consistent with the basic principles of moist static stability.
