IPRC Regional Ocean Atmosphere Model

PI: Simon de Szoeke
Institution: International Pacific Research Center
Abstract:
Coupled GCMs such as those in the AR4 intercomparison are improving but suffer biases in the eastern tropical Pacific. I would like comare the AR4 20th century control simulations with several years of hindcasts from the IPRC Regional Ocean Atmosphere Model (IROAM). IROAM is a coupled regional ocean-atmosphere-land model which combines an atmospheric model over the eastern Pacific with a basin-scale tropical Pacific Ocean model. IROAM simulates the meridional structure and seasonal evolution of SST, precipitation, and clouds reasonably well.

I am interested in the feedback of clouds and SST. I plan a comparison of simulations of the vertical structure of stratocumulus clouds, and how this affects cloud radiative forcing (especially of solar radiation) and SST.
