This new model integrations are carried out for the Geophysical Fluid Personality Research (GFDL) Atmospheric Design adaptation dos
1) Design runs made use of
1 (Delworth ainsi que al. 2006) presenting a restricted-volume dynamical core (Lin 2004) that have a horizontal quality of around 2° latitude and you can 24 vertical accounts. The atmospheric model is combined in order to an excellent slab ocean which have spatially consistent breadth. Four getup members with prescribed sea depths away from dos.cuatro, six, a dozen, twenty-four, and you can fifty yards try assessed within study. Brand new model is pressed by the seasonally varying insolation that have no eccentricity and you will ° obliquity, which can be run to possess twenty years, sufficient to converge on a reliable climatology. The fresh design climatology try obtained from the very last five years from this new integrations.

The seasonal migration of the ITCZ off the equator has a larger amplitude for shallower ocean depths (Fig. 8) and PPenny reaches as far as 21° in the 2.4-m slab depth run as compared to 3° in the 50-m slab depth run. This behavior is expected because the adjustment time scale of a 50-m-deep ocean to solar heating is on the order of one year (Donohoe 2011) as compared to weeks for 2.4-m-deep ocean. Thus, the SSTs barely adjust to the seasonally varying insolation in the 50-m run while the maximum SST moves seasonally with the insolation in the 2.4-m run. (altro…)
